Class CssCharStream

java.lang.Object
org.htmlunit.cssparser.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.
