PersistenceStorer	createEagerStorer(PersistenceTypeHandlerManager<D> typeManager, PersistenceObjectManager<D> objectManager, ObjectSwizzling objectRetriever, PersistenceTarget<D> target, BufferSizeProviderIncremental bufferSizeProvider)	Creates a PersistenceStorer instance with a storing logic that stores every instance that is encountered during the traversal of the entity graph once. Warning: This means that every (persistable) reference is traversed and every reachable instance is stored.
PersistenceStorer	createLazyStorer(PersistenceTypeHandlerManager<D> typeManager, PersistenceObjectManager<D> objectManager, ObjectSwizzling objectRetriever, PersistenceTarget<D> target, BufferSizeProviderIncremental bufferSizeProvider)	Creates a PersistenceStorer instance with a storing logic that stores instances that are encountered during the traversal of the entity graph that "require" to be stored.

createLazyStorer

public PersistenceStorer createLazyStorer(PersistenceTypeHandlerManager<D> typeManager, PersistenceObjectManager<D> objectManager, ObjectSwizzling objectRetriever, PersistenceTarget<D> target, BufferSizeProviderIncremental bufferSizeProvider)

Description copied from interface: PersistenceStorer.Creator

Creates a PersistenceStorer instance with a storing logic that stores instances that are encountered during the traversal of the entity graph that "require" to be stored. The actual meaning of being "required" depends on the implementation. An example for being "required" is not having an instance registered in the global object registry and associated an biunique OID.

Specified by:

createLazyStorer in interface PersistenceStorer.Creator<D>

Parameters:

typeManager - the provided type manager

objectManager - the provided object manager

objectRetriever - the provided object retriever

target - the provided persistence target

bufferSizeProvider - the provided buffer size provider

Returns:

a new lazy storer

createEagerStorer

public PersistenceStorer createEagerStorer(PersistenceTypeHandlerManager<D> typeManager, PersistenceObjectManager<D> objectManager, ObjectSwizzling objectRetriever, PersistenceTarget<D> target, BufferSizeProviderIncremental bufferSizeProvider)

Description copied from interface: PersistenceStorer.Creator

Creates a PersistenceStorer instance with a storing logic that stores every instance that is encountered during the traversal of the entity graph once.
Warning: This means that every (persistable) reference is traversed and every reachable instance is stored. Depending on the used data model, this can mean that the whole entity graph of an application is traversed and stored. This MIGHT be reasonable for very tiny applications, where storing simply means to start at the root entity and indiscriminately store every entity there is. Apart from this (rather academic) case, a storer with this logic should only be used for a confined entity sub-graph that has no reference "escaping" to the remaning entities.

Specified by:

createEagerStorer in interface PersistenceStorer.Creator<D>

Parameters:

typeManager - the provided type manager

objectManager - the provided object manager

objectRetriever - the provided object retriever

target - the provided persistence target

bufferSizeProvider - the provided buffer size provider

Returns:

a new eager storer
