## Class PatternSet

- java.lang.Object
- - org.apache.tools.ant.ProjectComponent
  - - org.apache.tools.ant.types.DataType
    - - org.apache.tools.ant.types.PatternSet

- All Implemented Interfaces:
    java.lang.Cloneable

      public class PatternSet
      extends DataType
      implements java.lang.Cloneable

  Named collection of include/exclude tags.

  Moved out of MatchingTask to make it a standalone object that could be referenced (by scripts for example).
