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

the logical or : the rule : left || null -> left null || right -> right null || null -> false left || right -> left || right

Overrides:
