Interface SimplifiableFunction

All Known Implementing Classes:
NorthFix
public interface SimplifiableFunction
Implemented by functions that can turn themselves into a simpler, more efficient expression, when certain conditions are met. Called by the SimplifyingfilterVisitor when the arguments of the function are not all literals (in which case, a one time simplification is performed instead).
