# 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`, `java.lang.Iterable<Resource>`, `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.

- ## Method Details

  - ### 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 containing filenames, separated by comma 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.

  - ### 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<Resource> iterator()
    Fulfill the ResourceCollection contract.
    Specified by:
      `iterator` in interface `java.lang.Iterable<Resource>`
    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
