one.microstream.persistence.binary.types

Class BinaryStorer.Default

java.lang.Object

one.microstream.persistence.binary.types.BinaryStorer.Default

All Implemented Interfaces:

BinaryStorer, PersistenceFunction, PersistenceLocalObjectIdRegistry<Binary>, PersistenceObjectIdRequestor<Binary>, PersistenceStoreHandler<Binary>, PersistenceStorer, PersistenceStoring, Storer

Direct Known Subclasses:

BinaryStorer.Eager

Enclosing interface:

BinaryStorer

public static class BinaryStorer.Default
extends Object
implements BinaryStorer, PersistenceStoreHandler<Binary>, PersistenceLocalObjectIdRegistry<Binary>

Default implementation that stores referenced instances only if required (i.e. if they have no OID assigned yet, therefore have not been stored yet, therefore require to be stored). It can be seen as a "lazy" or "on demand" storer as opposed toBinaryStorer.Eager.
For a more differentiated solution between the two simple, but extreme strategies, see PersistenceEagerStoringFieldEvaluator.
