Method Details

genericTypeOf

public static Class<?> genericTypeOf(Class<?> rootClass,
 Class<?> targetBaseClass,
 Class<?> targetBaseInterface)

Extract generic type of root class either from the target base class or from target base interface. Examples:

1. Foo implements IFoo[Integer]: genericTypeOf(Foo.class, Object.class, IFoo.class) returns Integer

2. Foo extends BaseFoo[String]: genericTypeOf(Foo.class, BaseFoo.class, IFoo.class) returns String

3. Foo extends BaseFoo; BaseFoo implements IFoo[String]: genericTypeOf(Foo.class, BaseFoo.class, Object.class) returns String

Does not support nested generics, only supports single type parameter.

Parameters:

rootClass - - the root class that the search begins from

targetBaseClass - - if one of the classes in the root class' hierarchy extends this base class it will be used for generic type extraction

targetBaseInterface - - if one of the interfaces in the root class' hierarchy implements this interface it will be used for generic type extraction

Returns:

generic interface if found, Object.class if not found.
