public class JevaParser

extends Object

implements JevaParserTreeConstants, JevaParserConstants

JevaParser: parse Java Expressions and Statements.

Includes minor Java syntax amendment for Jeva: Allow package statement with no name, for specifying an unnamed package.

JevaParser was generated by Sun's free Java parser generator JavaCC/JJTree (now maintained by the spinoff Metamata), using a modified version of the example Java grammar.
