Constructor Details

PersistenceLegacyTypeHandlerWrapper

public PersistenceLegacyTypeHandlerWrapper()

Method Details

New

public static <D, T> PersistenceLegacyTypeHandler<D,T> New(PersistenceTypeDefinition legacyTypeDefinition, PersistenceTypeHandler<D,T> currentTypeHandler)

dataType

public Class<D> dataType()

iterateInstanceReferences

public void iterateInstanceReferences(T instance, PersistenceFunction iterator)

iterateLoadableReferences

public void iterateLoadableReferences(D data, PersistenceReferenceLoader iterator)

create

public T create(D data, PersistenceLoadHandler handler)

updateState

public void updateState(D data, T instance, PersistenceLoadHandler handler)

complete

public void complete(D data, T instance, PersistenceLoadHandler handler)

Description copied from interface: PersistenceTypeHandler

Completes an initially built instance after all loaded instances have been built. E.g. can be used to cause a hash collection to hash all its initially collected entries after their instances have been built.

iterateMemberTypes

public <C extends Consumer<? super Class<?>>> C iterateMemberTypes(C logic)

Description copied from interface: PersistenceTypeHandler

Iterates the types of persistent members (e.g. non-transient Fields). The same type may occur more than once. The order in which the types are provided is undefined, i.e. depending on the implementation.

type

public final Class<T> type()

membersInDeclaredOrder

public XGettingEnum<? extends PersistenceTypeDefinitionMember> membersInDeclaredOrder()

storingMembers

public XGettingEnum<? extends PersistenceTypeDescriptionMember> storingMembers()

settingMembers

public XGettingEnum<? extends PersistenceTypeDescriptionMember> settingMembers()

guaranteeSpecificInstanceViablity

public void guaranteeSpecificInstanceViablity() throws PersistenceExceptionTypeNotPersistable

Description copied from interface: PersistenceTypeHandler

Guarantees that the PersistenceTypeHandler implementation is actually viably usable to handle instances. That is the natural purpose of type handlers, but there are exceptions, like type handlers created for abstract types or unpersistable types just to have a metadata representation that links a type and a type id.

See occurances of PersistenceExceptionTypeNotPersistable.

Throws:

PersistenceExceptionTypeNotPersistable

PersistenceExceptionTypeNotPersistable

isSpecificInstanceViable

public boolean isSpecificInstanceViable()

guaranteeSubTypeInstanceViablity

public void guaranteeSubTypeInstanceViablity() throws PersistenceExceptionTypeNotPersistable

Throws:

PersistenceExceptionTypeNotPersistable

isSubTypeInstanceViable

public boolean isSubTypeInstanceViable()

collectEnumConstants

public Object[] collectEnumConstants()

getPersistedEnumOrdinal

public int getPersistedEnumOrdinal(D data)
