initialize

public PersistenceTypeHandler<Binary,T> initialize(long typeId)

Specified by:

initialize in interface PersistenceTypeHandler<Binary,T>

dataType

public Class<Binary> dataType()

Specified by:

dataType in interface BinaryTypeHandler<T>

Specified by:

dataType in interface PersistenceDataTypeHolder<T>

Specified by:

dataType in interface PersistenceTypeHandler<Binary,T>

typeId

public long typeId()

Description copied from interface: PersistenceTypeDefinition

The biuniquely associated id value identifying a type description.

Specified by:

typeId in interface PersistenceTypeDefinition

Specified by:

typeId in interface PersistenceTypeIdentity

Specified by:

typeId in interface PersistenceTypeIdOwner

Specified by:

typeId in interface PersistenceTypeLink

typeName

public String typeName()

Description copied from interface: PersistenceTypeDefinition

The name of the type as defined in the type dictionary. This name may never change for a given typeId, even if the runtime PersistenceTypeDefinition.runtimeTypeName() did to reflect a design-level type renaming.

Specified by:

typeName in interface PersistenceTypeDefinition

Specified by:

typeName in interface PersistenceTypeDescription

Specified by:

typeName in interface PersistenceTypeIdentity

instanceReferenceMembers

public XGettingSequence<? extends PersistenceTypeDescriptionMember> instanceReferenceMembers()

Specified by:

instanceReferenceMembers in interface PersistenceTypeDescription

runtimeTypeName

public String runtimeTypeName()

Description copied from interface: PersistenceTypeDefinition

The name of the corresponding runtime type. If not implemented otherwise (e.g. to cache the name), this method simply calls Class.getName() of a non-null PersistenceTypeDefinition.type() reference.

Specified by:

runtimeTypeName in interface PersistenceTypeDefinition

type

public Class<T> type()

Specified by:

type in interface PersistenceTypeDefinition

Specified by:

type in interface PersistenceTypeHandler<Binary,T>

Specified by:

type in interface PersistenceTypeLink

isValidEntityType

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

Specified by:

isValidEntityType in interface PersistenceTypeHandler<Binary,T>

instancePrimitiveMembers

public XGettingSequence<? extends PersistenceTypeDescriptionMember> instancePrimitiveMembers()

Specified by:

instancePrimitiveMembers in interface PersistenceTypeDescription

validateEntityType

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

Specified by:

validateEntityType in interface PersistenceTypeHandler<Binary,T>

allMembers

public XGettingEnum<? extends PersistenceTypeDefinitionMember> allMembers()

Specified by:

allMembers in interface PersistenceTypeDefinition

Specified by:

allMembers in interface PersistenceTypeDescription

Specified by:

allMembers in interface PersistenceTypeHandler<Binary,T>

instanceMembers

public 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

Specified by:

instanceMembers in interface PersistenceTypeHandler<Binary,T>

iterateInstanceReferences

public void iterateInstanceReferences(T instance, PersistenceFunction iterator)

Specified by:

iterateInstanceReferences in interface PersistenceTypeHandler<Binary,T>

public void iterateLoadableReferences(Binary data, PersistenceReferenceLoader iterator)

Specified by:

create

public T create(Binary data, PersistenceLoadHandler handler)

Specified by:

create in interface PersistenceTypeHandler<Binary,T>

hasPersistedReferences

public boolean hasPersistedReferences()

Specified by:

hasPersistedVariableLength

public boolean hasPersistedVariableLength()

Description copied from interface: PersistenceTypeDefinition

Provides information if two instances of the handled type can have different length in persisted form.

Examples for variable length types:

• arrays
• java.lang.String
• java.util.ArrayList
• java.math.BigDecimal

Examples for fixed length types:

• primitive value wrapper types
• java.lang.Object
• java.util.Date
• typical entity types (without unshared inlined variable length component instances)

Specified by:

hasPersistedVariableLength in interface PersistenceTypeDefinition

updateState

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

Specified by:

updateState in interface PersistenceTypeHandler<Binary,T>

complete

public void complete(Binary 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.

Specified by:

complete in interface PersistenceTypeHandler<Binary,T>

isPrimitiveType

public boolean isPrimitiveType()

Specified by:

isPrimitiveType in interface PersistenceTypeDefinition

hasVaryingPersistedLengthInstances

public boolean hasVaryingPersistedLengthInstances()

Description copied from interface: PersistenceTypeDefinition

Provides information if one particular instance can have variing binary length from one store to another.

Examples for variable length instances:

• variable size collection instances
• variable size pesudo collection instances like java.util.StringBuilder
• instances of custom defined types similar to collections

Examples for fixed length instances:

• arrays
• all immutable type instances (like java.lang.String )
• all fixed length types (see PersistenceTypeDefinition.hasVaryingPersistedLengthInstances()

Specified by:

hasVaryingPersistedLengthInstances in interface PersistenceTypeDefinition

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.

public String toRuntimeTypeIdentifier()

Specified by:

toRuntimeTypeIdentifier in interface PersistenceTypeDefinition

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.

PersistenceExceptionTypeNotPersistable
