 Class<? extends Annotation> anno)

findGenericClassFor

public static Class<?> findGenericClassFor(Class<?> baseClass,
 Class<?> ifaceClass)

Given a Base (concrete) Class, find the interface specified, and return its concrete Generic class declaration.

Parameters:

baseClass - the base (concrete) class to look in

ifaceClass - the interface of interest

Returns:

the (concrete) generic class that the interface exposes

public static Type findGenericTypeFor(Class<?> baseClass,
 Class<?> ifaceClass)

isDefaultConstructable

public static boolean isDefaultConstructable(Class<?> clazz)

toString

public static String toString(Class<?> pojo,
 Method method)

append

 Method method)

append

public static void append(StringBuilder str,
 MethodType methodType)

isAssignableFrom

public static boolean isAssignableFrom(Type superType,
 Type subType)

Check if a type is assignable from another type. This only handles Class, ParameterizedType, and GenericArrayType, and does not handle wildcard types or type variables.

Parameters:

superType - the superType.

subType - the subType.

Returns:

true if the superType is assignable from the subType.
