Method Detail

isApplicable

public static int isApplicable(Type[] args,
                               Type[] params)

Discerns whether it would be legal to pass a sequence of references of the given source types to a method with parameters typed according to the specified sequence of destination types.

An example: suppose you have a method <T extends Number> mergeLists(List<T> list1, List<T> list2). It is legal to pass two List<Integer> instances to the method, but illegal to pass a List<Integer> and List<Double> because T cannot be both Integer and Double simultaneously.

Parameters:

args -

params -

Returns:

-1 if the args satisfy the params, otherwise the index of the arg that does not satisfy its parameter.
