Method Summary

Modifier and Type	Method	Description
PersistenceStorer<M>	createEagerStorer(PersistenceTypeHandlerManager<M> typeManager, PersistenceObjectManager objectManager, PersistenceObjectRetriever objectRetriever, PersistenceTarget<M> 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<M>	createLazyStorer(PersistenceTypeHandlerManager<M> typeManager, PersistenceObjectManager objectManager, PersistenceObjectRetriever objectRetriever, PersistenceTarget<M> 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.
default PersistenceStorer<M>	createStorer(PersistenceTypeHandlerManager<M> typeManager, PersistenceObjectManager objectManager, PersistenceObjectRetriever objectRetriever, PersistenceTarget<M> target, BufferSizeProviderIncremental bufferSizeProvider)	Creates a storer with a default or "natural" storing logic.

Method Detail

createLazyStorer

PersistenceStorer<M> createLazyStorer(PersistenceTypeHandlerManager<M> typeManager,
                                      PersistenceObjectManager objectManager,
                                      PersistenceObjectRetriever objectRetriever,
                                      PersistenceTarget<M> 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. 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.

Parameters:

objectManager -

objectRetriever -

typeManager -

target -

bufferSizeProvider -

createStorer

default PersistenceStorer<M> createStorer(PersistenceTypeHandlerManager<M> typeManager,
                                          PersistenceObjectManager objectManager,
                                          PersistenceObjectRetriever objectRetriever,
                                          PersistenceTarget<M> target,
                                          BufferSizeProviderIncremental bufferSizeProvider)

Creates a storer with a default or "natural" storing logic. The default for this method (the "default default" in a way) is to delegate the call to createLazyStorer(one.microstream.persistence.types.PersistenceTypeHandlerManager<M>, one.microstream.persistence.types.PersistenceObjectManager, one.microstream.persistence.types.PersistenceObjectRetriever, one.microstream.persistence.types.PersistenceTarget<M>, one.microstream.util.BufferSizeProviderIncremental).

Parameters:

objectManager -

objectRetriever -

typeManager -

target -

bufferSizeProvider -

createEagerStorer

PersistenceStorer<M> createEagerStorer(PersistenceTypeHandlerManager<M> typeManager,
                                       PersistenceObjectManager objectManager,
                                       PersistenceObjectRetriever objectRetriever,
                                       PersistenceTarget<M> 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. 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.

Parameters:

objectManager -

objectRetriever -

typeManager -

target -

bufferSizeProvider -
