evaluate
Calculates the value of the logical expression arg1 == arg2 All class types are supported. Uses equals() to determine equivalence. This should work as we represent with the types we already support, and anything else that implements equals() to mean more than identical references.- Specified by:
evaluate
in interfaceNode
- Overrides:
evaluate
in classSimpleNode
- Parameters:
context
- internal context used to evaluate the LHS and RHS- Returns:
- true if equivalent, false if not equivalent, false if not compatible arguments, or false if either LHS or RHS is null
- Throws:
MethodInvocationException

- Specified by:

in interfaceNode
- Overrides:
