getCandidates

boolean getCandidates(java.util.Map<Type,MethodMatcher.TypeVarCandidate> methodParCandidates)

<T, U extends Number> T map( U in ) Resolves all method generic parameter candidates

Parameters:

methodParCandidates - Map, keyed by the method generic parameter (T, U extends Number), with their respective candidates

Returns:

false no match or conflict has been found *

getCandidates

boolean getCandidates(Type aCandidateMethodType,
                      Type matchingType,
                      java.util.Map<Type,MethodMatcher.TypeVarCandidate> candidates)

Parameters:

aCandidateMethodType - parameter type or return type from candidate method

matchingType - source type / target type to match

candidates - Map, keyed by the method generic parameter, with the candidates

Returns:

false no match or conflict has been found

candidatesWithinBounds

private boolean candidatesWithinBounds(java.util.Map<Type,MethodMatcher.TypeVarCandidate> methodParCandidates)

Checks whether all found candidates are within the bounds of the method type var. For instance

Parameters:

methodParCandidates -

Returns:

true when all within bounds.

hasGenericTypeParameters
