Interface FileTree

All Superinterfaces:
AntBuilderAware, Buildable, FileCollection, Iterable<File>
All Known Subinterfaces:
ConfigurableFileTree, SourceDirectorySet
public interface FileTree extends FileCollection

A FileTree represents a hierarchy of files. It extends FileCollection to add hierarchy query and manipulation methods. You typically use a FileTree to represent files to copy or the contents of an archive.

You can obtain a FileTree instance using Project.fileTree(java.util.Map), Project.zipTree(Object) or Project.tarTree(Object).
