## Class DefaultGroovyMethods

- java.lang.Object
- - org.codehaus.groovy.runtime.DefaultGroovyMethodsSupport
  - - org.codehaus.groovy.runtime.DefaultGroovyMethods

-     public class DefaultGroovyMethods
      extends DefaultGroovyMethodsSupport

  This class defines new groovy methods which appear on normal JDK classes inside the Groovy environment. Static methods are used with the first parameter being the destination class, i.e. `public static String reverse(String self)` provides a `reverse()` method for `String`.

  NOTE: While this class contains many 'public' static methods, it is primarily regarded as an internal class (its internal package name suggests this also). We value backwards compatibility of these methods when used within Groovy but value less backwards compatibility at the Java method call level. I.e. future versions of Groovy may remove or move a method call in this file but would normally aim to keep the method available from within Groovy.

    - #### is

          public static boolean is(Object self,
                   Object other)

      Identity check. Since == is overridden in Groovy with the meaning of equality we need some fallback to check for object identity. Invoke using the 'is' method, like so: `def same = this.is(that)`
      Parameters:
        `self` - an object
        `other` - an object to compare identity with
      Returns:
        true if self and other are both references to the same instance, false otherwise

      Replaces the first substring of a String that matches the given compiled regular expression with the given replacement.

      Note that backslashes (`\`) and dollar signs (`$`) in the replacement string may cause the results to be different than if it were being treated as a literal replacement string; see `Matcher.replaceFirst(java.lang.String)`. Use `Matcher.quoteReplacement(java.lang.String)` to suppress the special meaning of these characters, if desired.

      Parameters:
        `self` - the string that is to be matched
        `pattern` - the regex Pattern to which the string of interest is to be matched
        `replacement` - the string to be substituted for the first match

    - #### replaceAll

          public static String replaceAll(String self,
                          Pattern pattern,
                          String replacement)

      Replaces all substrings of a String that match the given compiled regular expression with the given replacement.

      Note that backslashes (`\`) and dollar signs (`$`) in the replacement string may cause the results to be different than if it were being treated as a literal replacement string; see `Matcher.replaceAll(java.lang.String)`. Use `Matcher.quoteReplacement(java.lang.String)` to suppress the special meaning of these characters, if desired.

      Parameters:
        `self` - the string that is to be matched
        `pattern` - the regex Pattern to which the string of interest is to be matched
        `replacement` - the string to be substituted for the first match
      Returns:
        The resulting `String`

    - #### tr

          public static String tr(String self,
                  String sourceSet,
                  String replacementSet)
                           throws ClassNotFoundException

      Translates a string by replacing characters from the sourceSet with characters from replacementSet. If the first character from sourceSet appears in the string, it will be replaced with the first character from replacementSet. If the second character from sourceSet appears in the string, it will be replaced with the second character from replacementSet. and so on for all provided replacement characters.

      Here is an example which converts the vowels in a word from lower to uppercase:

           assert 'hello'.tr('aeiou', 'AEIOU') == 'hEllO'

      A character range using regex-style syntax can also be used, e.g. here is an example which converts a word from lower to uppercase:

           assert 'hello'.tr('a-z', 'A-Z') == 'HELLO'

      Hyphens at the start or end of sourceSet or replacementSet are treated as normal hyphens and are not considered to be part of a range specification. Similarly, a hyphen immediately after an earlier range is treated as a normal hyphen. So, '-x', 'x-' have no ranges while 'a-c-e' has the range 'a-c' plus the '-' character plus the 'e' character.

      Unlike the unix tr command, Groovy's tr command supports reverse ranges, e.g.:

           assert 'hello'.tr('z-a', 'Z-A') == 'HELLO'

      If replacementSet is smaller than sourceSet, then the last character from replacementSet is used as the replacement for all remaining source characters as shown here:

           assert 'Hello World!'.tr('a-z', 'A') == 'HAAAA WAAAA!'

      If sourceSet contains repeated characters, the last specified replacement is used as shown here:

           assert 'Hello World!'.tr('lloo', '1234') == 'He224 W4r2d!'

      The functionality provided by tr can be achieved using regular expressions but tr provides a much more compact notation and efficient implementation for certain scenarios.
      Parameters:
        `self` - the string that is to be translated
        `sourceSet` - the set of characters to translate from
        `replacementSet` - the set of replacement characters
      Returns:
        The resulting translated `String`
      Throws:
        `ClassNotFoundException`

    - #### matches

          public static boolean matches(String self,
                        Pattern pattern)

      Tells whether or not self matches the given compiled regular expression Pattern.
      Parameters:
        `self` - the string that is to be matched
        `pattern` - the regex Pattern to which the string of interest is to be matched
      Returns:
        The resulting `String`

    - #### find

          public static String find(String self,
                    String regex)

      Finds the first occurrence of a regular expression String within a String. If the regex doesn't match, null will be returned.

      For example, if the regex doesn't match the result is null:

               assert null == "New York, NY".find(/\d{5}/)

      If it does match, we get the matching string back:

                assert "10292" == "New York, NY 10292-0098".find(/\d{5}/)

      If we have capture groups in our expression, we still get back the full match

                assert "10292-0098" == "New York, NY 10292-0098".find(/(\d{5})-?(\d{4})/)

      Parameters:
        `self` - a String
        `regex` - the capturing regex
      Returns:
        a String containing the matched portion, or null if the regex doesn't match
      Since:
        1.6.1

    - #### find

          public static String find(String self,
                    Pattern pattern)

      Finds the first occurrence of a compiled regular expression Pattern within a String. If the pattern doesn't match, null will be returned.

      For example, if the pattern doesn't match the result is null:

               assert null == "New York, NY".find(~/\d{5}/)

      If it does match, we get the matching string back:

                assert "10292" == "New York, NY 10292-0098".find(~/\d{5}/)

      If we have capture groups in our expression, the groups are ignored and we get back the full match:

                assert "10292-0098" == "New York, NY 10292-0098".find(~/(\d{5})-?(\d{4})/)

      If you need to work with capture groups, then use the closure version of this method or use Groovy's matcher operators or use `eachMatch`.
      Parameters:
        `self` - a String
        `pattern` - the compiled regex Pattern
      Returns:
        a String containing the matched portion, or null if the regex pattern doesn't match
      Since:
        1.6.1

    - #### find

          public static String find(String self,
                    String regex,
                    Closure closure)

      Finds the first occurrence of a regular expression String within a String. If the regex doesn't match, the closure will not be called and find will return null.

      For example, if the regex doesn't match, the result is null:

               assert null == "New York, NY".find(~/\d{5}/) { match -> return "-$match-"}

      If it does match and we don't have any capture groups in our regex, there is a single parameter on the closure that the match gets passed to:

                assert "-10292-" == "New York, NY 10292-0098".find(~/\d{5}/) { match -> return "-$match-"}

      If we have capture groups in our expression, our closure has one parameter for the match, followed by one for each of the capture groups:

                assert "10292" == "New York, NY 10292-0098".find(~/(\d{5})-?(\d{4})/) { match, zip, plusFour ->
                    assert match == "10292-0098"
                    assert zip == "10292"
                    assert plusFour == "0098"
                    return zip
                }

      If we have capture groups in our expression, and our closure has one parameter, the closure will be passed an array with the first element corresponding to the whole match, followed by an element for each of the capture groups:

                assert "10292" == "New York, NY 10292-0098".find(~/(\d{5})-?(\d{4})/) { match, zip, plusFour ->
                    assert array[0] == "10292-0098"
                    assert array[1] == "10292"
                    assert array[2] == "0098"
                    return array[1]
                }

      If a capture group is optional, and doesn't match, then the corresponding value for that capture group passed to the closure will be null as illustrated here:

                assert "2339999" == "adsf 233-9999 adsf".find(~/(\d{3})?-?(\d{3})-(\d{4})/) { match, areaCode, exchange, stationNumber ->
                    assert "233-9999" == match
                    assert null == areaCode
                    assert "233" == exchange
                    assert "9999" == stationNumber
                    return "$exchange$stationNumber"
                }

      Parameters:
        `self` - a String
        `regex` - the capturing regex string
        `closure` - the closure that will be passed the full match, plus each of the capturing groups
      Returns:
        a String containing the result of the closure, or null if the regex pattern doesn't match

        1.6.1

    - #### find

          public static String find(String self,
                    Pattern pattern,
                    Closure closure)

      Finds the first occurrence of a compiled regular expression Pattern within a String. If the pattern doesn't match, the closure will not be called and find will return null.

      For example, if the pattern doesn't match, the result is null:

               assert null == "New York, NY".find(~/\d{5}/) { match -> return "-$match-"}

                    return zip
                }

                     Pattern pattern,
                     Closure closure)

      Finds all occurrences of a compiled regular expression Pattern within a String. Any matches are passed to the specified closure. The closure is expected to have the full match in the first parameter. If there are any capture groups, they will be placed in subsequent parameters.

      If there are no matches, the closure will not be called, and an empty List will be returned.

      For example, if the pattern doesn't match, it returns an empty list:

           assert [] == "foo".findAll(~/(\w*) Fish/) { match, firstWord -> return firstWord }

      Any regular expression matches are passed to the closure, if there are no capture groups, there will be one parameter for the match:

           assert ["couldn't", "wouldn't"] == "I could not, would not, with a fox.".findAll(~/.ould/) { match -> "${match}n't"}

      If there are capture groups, the first parameter will be the match followed by one parameter for each capture group:

           def orig = "There's a Wocket in my Pocket"
           assert ["W > Wocket", "P > Pocket"] == orig.findAll(~/(.)ocket/) { match, firstLetter -> "$firstLetter > $match" }

      Parameters:
        `self` - a String
        `pattern` - the compiled regex Pattern
        `closure` - will be passed the full match plus each of the capturing groups
      Returns:
        a List containing all full matches of the regex Pattern within the string, an empty list will be returned if there are no matches

    - #### replaceAll

          public static String replaceAll(String self,
                          String regex,
                          Closure closure)

      Replaces all occurrences of a captured group by the result of a closure on that text.

      For examples,

               assert "hellO wOrld" == "hello world".replaceAll("(o)") { it[0].toUpperCase() }

               assert "FOOBAR-FOOBAR-" == "foobar-FooBar-".replaceAll("(([fF][oO]{2})[bB]ar)", { Object[] it -> it[0].toUpperCase() })

               Here,
                    it[0] is the global string of the matched group
                    it[1] is the first string in the matched group
                    it[2] is the second string in the matched group

               assert "FOO-FOO-" == "foobar-FooBar-".replaceAll("(([fF][oO]{2})[bB]ar)", { x, y, z -> z.toUpperCase() })

               Here,
                    x is the global string of the matched group
                    y is the first string in the matched group
                    z is the second string in the matched group

      Note that unlike String.replaceAll(String regex, String replacement), where the replacement string treats '$' and '\' specially (for group substitution), the result of the closure is converted to a string and that value is used literally for the replacement.

      Parameters:
        `self` - a String
        `regex` - the capturing regex
        `closure` - the closure to apply on each captured group
      Returns:
        a String with replaced content
      Throws:
        `PatternSyntaxException` - if the regular expression's syntax is invalid

                            Closure closure)

      Replaces the first occurrence of a captured group by the result of a closure call on that text.

      For example (with some replaceAll variants thrown in for comparison purposes),

           assert "hellO wOrld" == "hello world".replaceAll("(o)") { it[0].toUpperCase() }   // all matches

           assert '1-FISH, two fish' == "one fish, two fish".replaceFirst(/([a-z]{3})\s([a-z]{4})/) { [one:1, two:2][it[1]] + '-' + it[2].toUpperCase() }

    - #### flatten

          public static Collection flatten(Collection self,
                           Closure flattenUsing)

      Flatten a collection. This collection and any nested arrays or collections have their contents (recursively) added to the new collection. For any non-Array, non-Collection object which represents some sort of collective type, the supplied closure should yield the contained items; otherwise, the closure should just return any element which corresponds to a leaf.
      Parameters:
        `self` - a Collection
        `flattenUsing` - a closure to determine how to flatten non-Array, non-Collection elements
      Returns:
        a flattened Collection

          def map = [a:1, b:2]
           map << [c:3, d:4]
           assert map == [a:1, b:2, c:3, d:4]

                                      IllegalArgumentException

      Invokes `closure` for each descendant file in this directory tree. Sub-directories are recursively traversed as found. The traversal can be adapted by providing various options in the `options` Map according to the following keys:
      type
        A `FileType` enum to determine if normal files or directories or both are processed
      preDir
        A `Closure` run before each directory is processed and optionally returning a `FileVisitResult` value which can be used to control subsequent processing.
      preRoot
        A boolean indicating that the 'preDir' closure should be applied at the root level
      postDir
        A `Closure` run after each directory is processed and optionally returning a `FileVisitResult` value which can be used to control subsequent processing.
      postRoot
        A boolean indicating that the 'postDir' closure should be applied at the root level
      visitRoot
        A boolean indicating that the given closure should be applied for the root dir (not applicable if the 'type' is set to `FileType.FILES`)
      maxDepth
        The maximum number of directory levels when recursing (default is -1 which means infinite, set to 0 for no recursion)
      filter
        A filter to perform on traversed files/directories (using the `isCase(java.lang.Object, java.lang.Object)` method). If set, only files/dirs which match are candidates for visiting.
      nameFilter
        A filter to perform on the name of traversed files/directories (using the `isCase(java.lang.Object, java.lang.Object)` method). If set, only files/dirs which match are candidates for visiting. (Must not be set if 'filter' is set)
      excludeFilter
        A filter to perform on traversed files/directories (using the `isCase(java.lang.Object, java.lang.Object)` method). If set, any candidates which match won't be visited.
      excludeNameFilter
        A filter to perform on the names of traversed files/directories (using the `isCase(java.lang.Object, java.lang.Object)` method). If set, any candidates which match won't be visited. (Must not be set if 'excludeFilter' is set)
      sort
        A `Closure` which if set causes the files and subdirectories for each directory to be processed in sorted order. Note that even when processing only files, the order of visited subdirectories will be affected by this parameter.
      This example prints out file counts and size aggregates for groovy source files within a directory tree:

           def totalSize = 0
           def count = 0
           def sortByTypeThenName = { a, b ->
               a.isFile() != b.isFile() ? a.isFile() <=> b.isFile() : a.name <=> b.name
           }
           rootDir.traverse(
                   type         : FILES,
                   nameFilter   : ~/.*\.groovy/,
                   preDir       : { if (it.name == '.svn') return SKIP_SUBTREE },
                   postDir      : { println "Found $count files in $it.name totalling $totalSize bytes"
                                   totalSize = 0; count = 0 },
                   postRoot     : true
                   sort         : sortByTypeThenName
           ) {it -> totalSize += it.size(); count++ }

      Parameters:
        `self` - a File
        `options` - a Map of options to alter the traversal behavior
        `closure` - the Closure to invoke on each file/directory and optionally returning a `FileVisitResult` value which can be used to control subsequent processing
      Throws:
        `FileNotFoundException` - if the given directory does not exist
