Class CssCharStream

java.lang.Object

com.steadystate.css.parser.CssCharStream

All Implemented Interfaces:

CharStream

public final class CssCharStream
extends Object
implements CharStream

An implementation of interface CharStream. There is no processing of escaping in this class because the escaping is part of the parser. CSS has some strange rules about that, so processing unicode escapes in this class is too early.
