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

org.apache.tools.ant.util.SourceFileScanner
Utility class that collects the functionality of the various scanDir methods that have been scattered in several tasks before.
The only method returns an array of source files. The array is a subset of the files given as a parameter and holds only those that are newer than their corresponding target files.
