equalsNode(ExprNode node)
Return true if a expression node semantically equals the current node, or false if not.

Returns the name of the type of cast to.

boolean |
isConstantResult()
Returns true if the expression node's evaluation value doesn't depend on any events data,
as must be determined at validation time, which is bottom-up and therefore
reliably allows each node to determine constant value.
