public class ClassBindings
extends Object

Stores a list of classes / interfaces and their associated deferred types. This list is used to tell LoremIpsumObjectCreator which specific implementation it should use to produce new dummy instances for a certain type. This is most useful to make sure Dummy Creator can create dummy objects for interface / abstract types it encounters.

Deferred types are produced by LoremIpsumObjectFactory implementations. Default factories are in place for strings, primitives, enums. In addition,there are factories that can be configured to invoke a specific Method (MethodBasedFactory) or a specific Constructor (ConstructorBasedFactory). Finally, there is a factory to return a fixed instance. The ClassBasedFactory is used automatically internally if no class binding can be found for a particular type. Examples are:

• List -> ArrayList (deferred to first succesfully invoked class constructor)
• List -> LinkedList (idem)
• Integer -> 4443 (which is autoboxed to an Integer and then acts as deferred instance)
• Foo -> FooFactory.class.getMethod('createFoo') (deferred to method call)
• Apple -> Apple.class.getConstructor(String.class) (deferred to constructor call)
• Apple -> new AppleFactory() (deferred to object factory call)

Method Detail

bind

public <T> void bind(Class<T> clazz,
                     LoremIpsumObjectFactory<? extends T> factory)

Binds a LoremIpsumObjectFactory to a specific Class instance.

Parameters:

clazz - The class to bind the dummy factory to.

factory - The factory to bind the the given class.

Throws:

IllegalArgumentException - Thrown if LoremIpsumObjectFactory.isValidForType(Class) returns false or throws an IllegalArgumentException itself.
