Method Detail

getClassHierarchy

public static List<Class<?>> getClassHierarchy(Class<?> c)

Gets a class hierarchy of a class as a list containing the class itself and all its super classes except of java.lang.Object. (bottom up)

Parameters:

c - The class

Returns:

List containing the class and all its super classes except of java.lang.Object

getInterfaceHierarchy

public static List<Class<?>> getInterfaceHierarchy(Class<?> c)

Gets a interface hierarchy of a class as a list containing the class's implemented interfaces and all their super interfaces. (bottom up)

Parameters:

c - The class

Returns:

List of classes that represent the interfaces

getFirstImplementation

public static Method getFirstImplementation(Class<?> c,
                                            Method method)

Looks for the first implementation or overriding of a method within the class hierarchy of the given class.

Parameters:

c - The class to look within the class hierarchy

method - The implemented or overridden method

Returns:

The first found implementing or overriding method

isMethodExchangeableBy

public static boolean isMethodExchangeableBy(Method method,
                                             Method candidateMethod)

Compares the name and parameters of both methods with each other and looks for the method parameters to be compatible with the candidate method parameters. Treats generic types as wild cards for any kind of type.

Parameters:

method - The method

candidateMethod - The candidate method

Returns:

true, if the method parameters are compatible, false otherwise
