Method Details

dataType

Class<D> dataType()

Specified by:

dataType in interface PersistenceDataTypeHolder<D>

type

Class<T> type()

Specified by:

type in interface PersistenceTypeDefinition

Specified by:

type in interface PersistenceTypeLink

isValidEntityType

default boolean isValidEntityType(Class<? extends T> type)

validateEntityType

default void validateEntityType(Class<? extends T> type)

allMembers

XGettingEnum<? extends PersistenceTypeDefinitionMember> allMembers()

Specified by:

allMembers in interface PersistenceTypeDefinition

Specified by:

allMembers in interface PersistenceTypeDescription

instanceMembers

XGettingEnum<? extends PersistenceTypeDefinitionMember> instanceMembers()

Description copied from interface: PersistenceTypeDefinition

Enum (unique elements with order), using PersistenceTypeDescriptionMember.identityHashEqualator(). Contains all persistent members (similar, but not identical to fields) in persistent order, which can differ from the declaration order.

Specified by:

instanceMembers in interface PersistenceTypeDefinition

Specified by:

instanceMembers in interface PersistenceTypeDescription

iterateInstanceReferences

void iterateInstanceReferences(T instance, PersistenceFunction iterator)

iterateLoadableReferences

void iterateLoadableReferences(D data, PersistenceReferenceLoader iterator)

store

void store(D data, T instance, long objectId, PersistenceStoreHandler<D> handler)

create

T create(D data, PersistenceLoadHandler handler)

initializeState

default void initializeState(D data, T instance, PersistenceLoadHandler handler)

updateState

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

complete

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

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.

Parameters:

data - the data target

instance - the source instance

handler - the appropriate handler

initialize

PersistenceTypeHandler<D,T> initialize(long typeId)

iterateMemberTypes

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

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 Parameters:

C - the logic type

Parameters:

logic - the iteration logic

Returns:

the given logic

membersInDeclaredOrder

default XGettingEnum<? extends PersistenceTypeDefinitionMember> membersInDeclaredOrder()

storingMembers

default XGettingEnum<? extends PersistenceTypeDescriptionMember> storingMembers()

settingMembers

default XGettingEnum<? extends PersistenceTypeDescriptionMember> settingMembers()

guaranteeSpecificInstanceViablity

default void guaranteeSpecificInstanceViablity() throws PersistenceExceptionTypeNotPersistable

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 - if the handler's type is not persistable

See Also:

PersistenceExceptionTypeNotPersistable

isSpecificInstanceViable

default boolean isSpecificInstanceViable()

guaranteeSubTypeInstanceViablity

default void guaranteeSubTypeInstanceViablity() throws PersistenceExceptionTypeNotPersistable

Throws:

PersistenceExceptionTypeNotPersistable

isSubTypeInstanceViable

default boolean isSubTypeInstanceViable()

collectEnumConstants

default Object[] collectEnumConstants()

getPersistedEnumOrdinal

default int getPersistedEnumOrdinal(D data)

resolveEnumConstant

static <T, M> T resolveEnumConstant(Class<T> type, int ordinal)
