Class ExprParser

java.lang.Object
oracle.rules.sdk.editor.ruleset.ExprParser

public class ExprParser

extends java.lang.Object

Scans an input expression string, and if successful, parses the string. Creates an ordered array of Tokens. Determines which token the cursor is in. Analyzes the expression to determine if it will yield the correct type.

Nested Class Summary

class

ExprParser.Token Token represents a lexeme in a parsed expression.
