 Class<?> target)

getMethods

public static void getMethods(IPredicate<Method> condition,
 Class<?> target,
 ArrayList<Method> methods)

getOverridingMethod

public static Method getOverridingMethod(Method overridingMethod,
 Class subclass)

Traverses the class hierarchy upwards, starting at the given subclass, looking for an override of the given methods -> finds the bottom most override of the given method if any exists

Parameters:

overridingMethod -

subclass -

getSuperTypes

public static Class[] getSuperTypes(Class from)

Collect all directly and indirectly related super types (classes and interfaces) of a given class.

Parameters:

from - The root class to start with

Returns:

A set of classes, each representing a super type of the root class

getAnnotation

private static <A extends Annotation> A getAnnotation(AnnotatedElement from,
 Class<A> annotationType,
 Set<AnnotatedElement> visited)

Searches for an Annotation of the given type on the class. Supports meta annotations.

Type Parameters:

A - Class of annotation type

Parameters:

from - AnnotatedElement (class, method...)

annotationType - Annotation class to look for.

Returns:

Annotation instance or null
