Interface MixinHolder

public interface MixinHolder

Interface to enable the XBProjector to register mixins. Will be removed when the Java 6 & 7 support is dropped.

Method Summary

Modifier and Type	Method and Description
<S,M extends S,P extends S> XBProjector	addProjectionMixin(Class<P> projectionInterface, M mixinImplementation) Register a new mixin for a projection interface.
<S,M extends S,P extends S> M	getProjectionMixin(Class<P> projectionInterface, Class<M> mixinInterface) Get the mixin implementation registered for the given projection.
<S,M extends S,P extends S> M	removeProjectionMixin(Class<P> projectionInterface, Class<M> mixinInterface) Remove the mixin implementation registered for the given projection.

Method Detail

addProjectionMixin

<S,M extends S,P extends S> XBProjector addProjectionMixin(Class<P> projectionInterface,
                                                           M mixinImplementation)

Register a new mixin for a projection interface. By letting a projection extend another interface you are able to add custom behavior to projections by registering an implementation (called a mixin) of this interface here. A mixin is registered per projection type. Only one mixin implementation per projection and mixin type is possible. All existing and all future projection instances will change. Notice that you will break projection serialization if you register a non serializeable mixin.

Parameters:

projectionInterface -

mixinImplementation -

Returns:

this for convenience

getProjectionMixin

<S,M extends S,P extends S> M getProjectionMixin(Class<P> projectionInterface,
                                                 Class<M> mixinInterface)

Get the mixin implementation registered for the given projection.

Parameters:

projectionInterface -

mixinInterface -

Returns:

the registered mixin implementation. null if none is present.

removeProjectionMixin

<S,M extends S,P extends S> M removeProjectionMixin(Class<P> projectionInterface,
                                                    Class<M> mixinInterface)

Remove the mixin implementation registered for the given projection.

Parameters:

projectionInterface -

mixinInterface -

Returns:

the registered mixin implementation. null if none was present.
