## org.apache.xml.serializer.utils
Class SystemIDResolver

    java.lang.Object
      |
      +--org.apache.xml.serializer.utils.SystemIDResolver

public final class SystemIDResolver
extends java.lang.Object

This class is used to resolve relative URIs and SystemID strings into absolute URIs.

This is a generic utility for resolving URIs, other than the fact that it's declared to throw TransformerException. Please see code comments for details on how resolution is performed.

This class is a copy of the one in org.apache.xml.utils. It exists to cut the serializers dependancy on that package. This class is not a public API, it is only public because it is used in org.apache.xml.serializer.

Usage:
  **For internal use only**

Constructor Summary
`SystemIDResolver()`

Method Summary
`static java.lang.String` | `getAbsoluteURI(java.lang.String systemId)` Take a SystemID string and try to turn it into a good absolute URI.
`static java.lang.String` | `getAbsoluteURI(java.lang.String urlString, java.lang.String base)` Take a SystemID string and try to turn it into a good absolute URI.
`static java.lang.String` | `getAbsoluteURIFromRelative(java.lang.String localPath)` Get an absolute URI from a given relative URI (local path).
`static boolean` | `isAbsolutePath(java.lang.String systemId)` Return true if the local path is an absolute path.
`static boolean` | `isAbsoluteURI(java.lang.String systemId)` Return true if the systemId denotes an absolute URI .

Method Detail

### getAbsoluteURIFromRelative

    public static java.lang.String getAbsoluteURIFromRelative(java.lang.String localPath)

  Get an absolute URI from a given relative URI (local path).

  The relative URI is a local filesystem path. The path can be absolute or relative. If it is a relative path, it is resolved relative to the system property "user.dir" if it is available; if not (i.e. in an Applet perhaps which throws SecurityException) then we just return the relative path. The space and backslash characters are also replaced to generate a good absolute URI.

  Parameters:
    `localPath` - The relative URI to resolve
  Returns:
    Resolved absolute URI

### isAbsoluteURI

    public static boolean isAbsoluteURI(java.lang.String systemId)

  Return true if the systemId denotes an absolute URI .
  Parameters:
    `systemId` - The systemId string
  Returns:
    true if the systemId is an an absolute URI

### isAbsolutePath

    public static boolean isAbsolutePath(java.lang.String systemId)

  Return true if the local path is an absolute path.
  Parameters:
    `systemId` - The path string
  Returns:
    true if the path is absolute

### getAbsoluteURI

    public static java.lang.String getAbsoluteURI(java.lang.String systemId)

  Take a SystemID string and try to turn it into a good absolute URI.
  Parameters:
    `systemId` - A URI string, which may be absolute or relative.
  Returns:
    The resolved absolute URI

### getAbsoluteURI

    public static java.lang.String getAbsoluteURI(java.lang.String urlString,
                                                  java.lang.String base)
                                           throws TransformerException

  Take a SystemID string and try to turn it into a good absolute URI.
  Parameters:
    `urlString` - SystemID string
    `base` - The URI string used as the base for resolving the systemID
  Returns:
    The resolved absolute URI
  Throws:
    TransformerException - thrown if the string can't be turned into a URI.
