Method Detail

jjtAccept

public java.lang.Object jjtAccept(ParserVisitor visitor,
                                  java.lang.Object data)
Accept the visitor.
Overrides:
jjtAccept in class SimpleNode

value

public java.lang.Object value(InternalContextAdapter context)
                       throws MethodInvocationException
Returns the value of the expression. Since the value of the expression is simply the boolean result of evaluate(), lets return that.
Overrides:
value in class SimpleNode

evaluate

public boolean evaluate(InternalContextAdapter context)
                 throws MethodInvocationException
logical and : null && right = false left && null = false null && null = false
Overrides:
evaluate in class SimpleNode
