Method Detail

delete

public static void delete(String dir,
                          boolean recurse,
                          boolean delete,

handleItem

public boolean handleItem(File f,
                          int howDeep)

Defines DirectoryItemHandler.
Deletes the current File in a directory tree traversal. Uses indenting to show the level of the traversal.

Specified by:

handleItem in interface DirectoryItemHandler

Parameters:

f - the current File being handled by DirectoryTree.traverse.

howDeep - how "deep" the traversal is in the tree, with respect to the root folder in the local filesystem. (i.e., if the current file is: /foo/bar/a/b/x.txt and the root of the traversal was specified as /foo/bar, then howDeep == 2.)

Returns:

true if the traversal is free to continue; false if it shoul dbe short-circuited
