Examples of org.apache.tools.ant.util.FileNameMapper

org.apache.tools.ant.util.FileNameMapper
Interface to be used by SourceFileScanner.
Used to find the name of the target file(s) corresponding to a source file.

The rule by which the file names are transformed is specified via the setFrom and setTo methods. The exact meaning of these is implementation dependent.
