public class Move

extends Copy

Moves a file or directory to a new file or directory. By default, the destination file is overwritten if it already exists. When overwrite is turned off, then files are only moved if the source file is newer than the destination file, or when the destination file does not exist.

Source files and directories are only deleted when the file or directory has been copied to the destination successfully. Filtering also works.

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

Ant 1.2

Method Detail

doFileOperations

protected void doFileOperations()

Description copied from class: Copy

Actually does the file (and possibly empty directory) copies. This is a good method for subclasses to override.

Overrides:

doFileOperations in class Copy

okToDelete

protected boolean okToDelete(java.io.File d)

Its only ok to delete a directory tree if there are no files in it.

Returns:

true if a deletion can go ahead

deleteDir

protected void deleteDir(java.io.File d)

Go and delete the directory tree.

renameFile

protected boolean renameFile(java.io.File sourceFile,
                             java.io.File destFile,
                             boolean filtering,
                             boolean overwrite)
                      throws java.io.IOException,
                             BuildException

Attempts to rename a file from a source to a destination. If overwrite is set to true, this method overwrites existing file even if the destination file is newer. Otherwise, the source file is renamed only if the destination file is older than it. Method then checks if token filtering is used. If it is, this method returns false assuming it is the responsibility to the copyFile method.

Throws:

java.io.IOException

BuildException
