Class Copy

  • All Implemented Interfaces:
    java.lang.Cloneable
    Direct Known Subclasses:
    Move, Sync.MyCopy

    public class Copy
    extends Task

    Copies a file or directory to a new file or directory. Files are only copied if the source file is newer than the destination file, or when the destination file does not exist. It is possible to explicitly overwrite existing files.

    This implementation is based on Arnout Kuiper's initial design document, the following mailing list discussions, and the copyfile/copydir tasks.

    Since:
    Ant 1.2

      • supportsNonFileResources

        protected boolean supportsNonFileResources()
        Whether this task can deal with non-file resources.

        <copy> can while <move> can't since we don't know how to remove non-file resources.

        This implementation returns true only if this task is <copy>. Any subclass of this class that also wants to support non-file resources needs to override this method. We need to do so for backwards compatibility reasons since we can't expect subclasses to support resources.

        Returns:
        true if this task supports non file resources.
