Method Detail

jjtAccept

public Object jjtAccept(ParserVisitor visitor,
                        Object data)
Specified by:
jjtAccept in interface Node
Overrides:
jjtAccept in class SimpleNode
Returns:
The Node execution result object.
See Also:
SimpleNode.jjtAccept(org.apache.velocity.runtime.parser.node.ParserVisitor, java.lang.Object)

value

public 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.

Specified by:
value in interface Node
Overrides:
value in class SimpleNode
Parameters:
context -
Returns:
The Expression value.
Throws:
MethodInvocationException
See Also:
Node.value(org.apache.velocity.context.InternalContextAdapter)

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

Specified by:
evaluate in interface Node
Overrides:
evaluate in class SimpleNode
Parameters:
context -
Returns:
The evaluation result.
Throws:
MethodInvocationException
See Also:
Node.evaluate(org.apache.velocity.context.InternalContextAdapter)
