Method Detail

evaluate

public boolean evaluate(InternalContextAdapter context)

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.

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

jjtAccept

public Object jjtAccept(ParserVisitor visitor, Object data)

Accept the visitor. *

value

public Object value(InternalContextAdapter context)
