Method Detail

public static <T> Map<TypeVariable<Class<T>>,Class<?>> getTypeArgumentsMap(Class<? extends T> childClass,
 Class<T> baseClass)

The map of type arguments of baseClass to actual type for childClass.

Type Parameters:: T - the type of the baseClass.
Parameters:: childClass - the class to test, eg Props.class with Props extends Map.; baseClass - the generic superclass, eg Map.class.
Returns:: a the map, eg {K => String.class, V => null}.

public static <T> List<Class<?>> getTypeArguments(Class<? extends T> childClass,
 Class<T> baseClass)

Search for the list of class used to extend/implement a generic class/interface.

Type Parameters:: T - the type of the baseClass.
Parameters:: childClass - the class to test, eg Props.class with Props extends Map.; baseClass - the generic superclass, eg Map.class.
Returns:: the list of actual classes w/o the possible nulls (if childClass is generic), never null, eg [Boolean.class].

public static <U> List<Class<?>> getTypeArguments(U o,
 Class<U> raw)

public static <U> boolean isCastable(U o,
 Class<U> raw,
 Class... typeArgs)

Whether o can be casted to raw<typeArgs>.

Type Parameters:: U - type of the superclass.
Parameters:: o - the instance to check, eg new MapOfInt2Boolean().; raw - the generic superclass, eg Map.class.; typeArgs - arguments to raw, eg Integer.class, Boolean.class.
Returns:: whether o is a raw<typeArgs>, eg true : new MapOfInt2Boolean() is a Map<Integer, Boolean>.
