## org.apache.tools.ant.types
Class FileList

    java.lang.Object
      org.apache.tools.ant.ProjectComponent
          org.apache.tools.ant.types.DataType
              org.apache.tools.ant.types.FileList

All Implemented Interfaces:
  java.lang.Cloneable, ResourceCollection

    public class FileList

extends DataType
implements ResourceCollection

FileList represents an explicitly named list of files. FileLists are useful when you want to capture a list of files regardless of whether they currently exist. By contrast, FileSet operates as a filter, only returning the name of a matched file if it currently exists in the file system.

Nested Class Summary
`static class` | `FileList.FileName` Inner class corresponding to the <file> nested element.

Constructor Detail

### FileList

    public FileList()

  The default constructor.

### FileList

    protected FileList(FileList filelist)

  A copy constructor.

  Parameters:
    `filelist` - a `FileList` value

Method Detail

### setRefid

    public void setRefid(Reference r)
                  throws BuildException

  Makes this instance in effect a reference to another FileList instance.

  You must not set another attribute or nest elements inside this element if you make it a reference.

  Overrides:
    `setRefid` in class `DataType`
  Parameters:
    `r` - the reference to another filelist.
  Throws:
    `BuildException` - if an error occurs.

### setDir

    public void setDir(java.io.File dir)
                throws BuildException

  Set the dir attribute.

  Parameters:
    `dir` - the directory this filelist is relative to.
  Throws:
    `BuildException` - if an error occurs

### getDir

    public java.io.File getDir(Project p)

  Parameters:
    `p` - the current project
  Returns:
    the directory attribute

### setFiles

    public void setFiles(java.lang.String filenames)

  Set the filenames attribute.

  Parameters:
    `filenames` - a string contains filenames, separated by , or by whitespace.

### getFiles

    public java.lang.String[] getFiles(Project p)

  Returns the list of files represented by this FileList.

  Parameters:
    `p` - the current project
  Returns:
    the list of files represented by this FileList.

### getRef

    protected FileList getRef(Project p)

  Performs the check for circular references and returns the referenced FileList.

  Parameters:
    `p` - the current project
  Returns:
    the FileList represented by a referenced filelist.

### addConfiguredFile

    public void addConfiguredFile(FileList.FileName name)

  Add a nested <file> nested element.

  Parameters:
    `name` - a configured file element with a name.
  Since:
    Ant 1.6.2

### iterator

    public java.util.Iterator iterator()

  Fulfill the ResourceCollection contract.

  Specified by:
    `iterator` in interface `ResourceCollection`
  Returns:
    an Iterator of Resources.
  Since:
    Ant 1.7

### size

    public int size()

  Fulfill the ResourceCollection contract.

  Specified by:
    `size` in interface `ResourceCollection`
  Returns:
    number of elements as int.
  Since:
    Ant 1.7

### isFilesystemOnly

    public boolean isFilesystemOnly()

  Always returns true.

  Specified by:
    `isFilesystemOnly` in interface `ResourceCollection`
  Returns:
    true indicating that all elements will be FileResources.
  Since:
    Ant 1.7
