    public class ClassfileSet

extends FileSet

A ClassfileSet is a FileSet that enlists all classes that depend on a certain set of root classes. ClassfileSet extends FileSet, its inherited properties defining the domain searched for dependent classes.

Nested Class Summary
`static class` | `ClassfileSet.ClassRoot` Inner class used to contain info about root classes.

Field Summary

Fields inherited from class org.apache.tools.ant.types.DataType
`checked, ref`

Fields inherited from class org.apache.tools.ant.ProjectComponent
`description, location, project`

Constructor Summary
`` | `ClassfileSet()` Default constructor.
`protected` | `ClassfileSet(ClassfileSet s)` Create a ClassfileSet from another ClassfileSet.

Method Summary
`void` | `addConfiguredRoot(ClassfileSet.ClassRoot root)` Add a nested root class definition to this class file set.
`void` | `addRootFileset(FileSet rootFileSet)` Add a fileset to which contains a collection of root classes used to drive the search from classes.
`java.lang.Object` | `clone()` Clone this data type.
`protected void` | `dieOnCircularReference(java.util.Stack stk, Project p)` Check to see whether any DataType we hold references to is included in the Stack (which holds all DataType instances that directly or indirectly reference this instance, including this instance itself).
`DirectoryScanner` | `getDirectoryScanner(Project p)` Return the DirectoryScanner associated with this FileSet.
`void` | `setRootClass(java.lang.String rootClass)` Set the root class attribute.

Constructor Detail

### ClassfileSet

    public ClassfileSet()

  Default constructor.

### ClassfileSet

    protected ClassfileSet(ClassfileSet s)

  Create a ClassfileSet from another ClassfileSet.

  Parameters:
    `s` - the other classfileset.

Method Detail

### addRootFileset

    public void addRootFileset(FileSet rootFileSet)

  Add a fileset to which contains a collection of root classes used to drive the search from classes.

  Parameters:
    `rootFileSet` - a root file set to be used to search for dependent classes.

### setRootClass

    public void setRootClass(java.lang.String rootClass)

  Set the root class attribute.

  Parameters:
    `rootClass` - the name of the root class.

### getDirectoryScanner

    public DirectoryScanner getDirectoryScanner(Project p)

  Return the DirectoryScanner associated with this FileSet.

  Overrides:
    `getDirectoryScanner` in class `AbstractFileSet`
  Parameters:
    `p` - the project used to resolve dirs, etc.
  Returns:
    a dependency scanner.

### addConfiguredRoot

    public void addConfiguredRoot(ClassfileSet.ClassRoot root)

  Add a nested root class definition to this class file set.

  Parameters:
    `root` - the configured class root.

### clone

    public java.lang.Object clone()

  Clone this data type.

  Overrides:
    `clone` in class `FileSet`
  Returns:
    a clone of the class file set.

### dieOnCircularReference

    protected void dieOnCircularReference(java.util.Stack stk,
                                          Project p)

  Description copied from class: `DataType`
  Check to see whether any DataType we hold references to is included in the Stack (which holds all DataType instances that directly or indirectly reference this instance, including this instance itself).

  If one is included, throw a BuildException created by `circularReference`.

  This implementation is appropriate only for a DataType that cannot hold other DataTypes as children.

  The general contract of this method is that it shouldn't do anything if ``checked`` is true and set it to true on exit.

  Overrides:
    `dieOnCircularReference` in class `AbstractFileSet`
  Parameters:
    `stk` - the stack of references to check.
    `p` - the project to use to dereference the references.
