## Class StripJavaComments

- java.lang.Object
- - java.io.Reader
  - - java.io.FilterReader
    - - org.apache.tools.ant.filters.BaseFilterReader
      - - org.apache.tools.ant.filters.StripJavaComments

- All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable, java.lang.Readable, ChainableReader

      public final class StripJavaComments
      extends BaseFilterReader
      implements ChainableReader

  This is a Java comment and string stripper reader that filters those lexical tokens out for purposes of simple Java parsing. (if you have more complex Java parsing needs, use a real lexer). Since this class heavily relies on the single char read function, you are recommended to make it work on top of a buffered reader.
