public static Class<?> genericTypeOf(Class<?> rootClass, Class<?> targetBaseClass, Class<?> targetBaseInterface)
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.
rootClass
- - the root class that the search begins fromtargetBaseClass
- - if one of the classes in the root class' hierarchy extends this base class
it will be used for generic type extractiontargetBaseInterface
- - if one of the interfaces in the root class' hierarchy implements this interface
it will be used for generic type extraction
