Interface InstanceInitializer

public interface InstanceInitializer

When using the Hibernate Core integration (for example) we need to make sure that the entities and collections we're working on are initialized. Initialization strategies might vary according to the integrating framework; when integrating with Infinispan (as Infinispan Query) no initialization is needed.

Method Detail

getClass

<T> Class<T> getClass(T entity)

Type Parameters:

T - the type of the entity

Parameters:

entity - an instance or proxy of T

Returns:

the class from the instance, or the underlying class from a proxy.

unproxy

Object unproxy(Object value)

Parameters:

value - the object to unproxy

Returns:

if value is a proxy, unwraps it, otherwise works as a pass-through function.

initializeCollection

Type Parameters:

T - the type of the elements in the collection

Parameters:

value - the collection to initialize

Returns:

the initialized Collection, to be used on lazily-loading collections

initializeMap

<K,V> Map<K,V> initializeMap(Map<K,V> value)

Type Parameters:

K - key

V - value

Parameters:

value - the map to initialize

Returns:

the initialized Map, to be used on lazily-loading maps

initializeArray

Object[] initializeArray(Object[] value)

Parameters:

value - the array to initialize

Returns:

the initialized array, to be used on lazily-loading arrays

getIndexedTypeIdFromWork

IndexedTypeIdentifier getIndexedTypeIdFromWork(Work work)

Parameters:

work -

Returns:

the identification of the user type being indexed
