determineCustomMethods

static java.util.Map<java.lang.Class<?>,java.util.List<java.lang.reflect.Method>> determineCustomMethods(java.lang.Class<?> target,
                                                                                                         java.lang.String methodName,
                                                                                                         java.lang.Class<?>[] possibleArgumentTypes,
                                                                                                         boolean onlyPublic)

Specialised reflection utility that determines all methods that accept two parameters such:

 methodName(Type serviceType, Type1 arg)
 
 methodName(Type serviceType, Type2 arg)
 
 methodName(AnotherType serviceType, Type1 arg)
 
 methodName(Type serviceType) 

It will return a map which has the serviceType (first argument) as type and contains as list the variants of methods using the second argument. This method is normally used by listeners when determining custom methods.

Parameters:

target -

methodName -

possibleArgumentTypes -

modifier -

Returns:

Shortcut method that uses as possible argument types, Dictionary.class, Map.class or even nothing.

Parameters:

target -

methodName -

Returns:

invokeCustomMethods

static void invokeCustomMethods(java.lang.Object target,
                                java.util.Map<java.lang.Class<?>,java.util.List<java.lang.reflect.Method>> methods,
                                java.lang.Object service,
                                java.util.Map properties)

Invoke the custom listener method. Takes care of iterating through the method map (normally acquired through #determineCustomMethods(Class, String, Class[]) and invoking the method using the arguments.

Parameters:

target -

methods -

service -

properties -
