All Implemented Interfaces: 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 reccomended to make it work on top of a buffered reader.
