net.sourceforge.htmlunit.corejs.javascript.Parser

This class implements the JavaScript parser.

It is based on the SpiderMonkey C source files jsparse.c and jsparse.h in the jsref package.

The parser generates an {@link AstRoot} parse tree representing the sourcecode. No tree rewriting is permitted at this stage, so that the parse tree is a faithful representation of the source for frontend processing tools and IDEs.

This parser implementation is not intended to be reused after a parse finishes, and will throw an IllegalStateException() if invoked again.
