implementsMap

private static boolean implementsMap(ClassDescriptor d)

Determine from the class descriptor for a variable whether that variable implements java.util.Map.

Parameters:

d - class descriptor for variable we want to check implements Map

Returns:

true iff the descriptor corresponds to an implementor of Map
