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.- Specified by:

value
in classSimpleNode
- Parameters:
context
-- Returns:
- The value of the expression.

evaluate
public boolean evaluate(InternalContextAdapter context) throws MethodInvocationException
logical and : null && right = false left && null = false null && null = false- Specified by:
evaluate
in interfaceNode
- Overrides:
evaluate
in classSimpleNode
- Parameters:
context
-- Returns:
- True if both sides are true.
