Class GlobPatternMapper

Implemented Interfaces:
FileNameMapper
Known Direct Subclasses:
PackageNameMapper, UnPackageNameMapper

public class GlobPatternMapper
extends java.lang.Object
implements FileNameMapper

Implementation of FileNameMapper that does simple wildcard pattern replacements.

This does simple translations like *.foo -> *.bar where the prefix to .foo will be left unchanged. It only handles a single * character, use regular expressions for more complicated situations.

This is one of the more useful Mappers, it is used by javac for example.
