Class StripJavaComments

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.

Constructor Summary
	StripJavaComments() Constructor for "dummy" instances.
	StripJavaComments(Reader in) Creates a new filtered reader.

Method Summary
Reader	chain(Reader rdr) Creates a new StripJavaComments using the passed in Reader for instantiation.
int	read() Returns the next character in the filtered stream, not including Java comments.
