## Class ScriptFilter

- java.lang.Object
- - org.apache.tools.ant.ProjectComponent
  - - org.apache.tools.ant.filters.TokenFilter.ChainableReaderFilter
    - - org.apache.tools.ant.types.optional.ScriptFilter

- All Implemented Interfaces:
    java.lang.Cloneable, ChainableReader, TokenFilter.Filter

      public class ScriptFilter
      extends TokenFilter.ChainableReaderFilter

  Most of this is CAP (Cut And Paste) from the Script task ScriptFilter class, implements TokenFilter.Filter for scripts to use. This provides the same beans as the Script Task to a script. The script is meant to use get self.token and set self.token in the reply.
  Since:
    Ant 1.6
