Method Detail

typeId

public final 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 final 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

runtimeTypeName

public final 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 final Class<?> type()

Specified by:

type in interface PersistenceTypeDefinition

Specified by:

type in interface PersistenceTypeLink

allMembers

public final XImmutableEnum<? extends PersistenceTypeDefinitionMember> allMembers()

Specified by:

allMembers in interface PersistenceTypeDefinition

Specified by:

allMembers in interface PersistenceTypeDescription

instanceMembers

public final XImmutableEnum<? 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

hasPersistedReferences

public final boolean hasPersistedReferences()

Specified by:

hasPersistedReferences in interface PersistenceTypeDefinition

isPrimitiveType

public final boolean isPrimitiveType()

Specified by:

isPrimitiveType in interface PersistenceTypeDefinition

hasPersistedVariableLength

public final 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

hasVaryingPersistedLengthInstances

public final 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

toString

public final String toString()

Overrides:

toString in class Object

membersPersistedLengthMinimum

public final long membersPersistedLengthMinimum()

Specified by:

membersPersistedLengthMinimum in interface PersistenceTypeDefinition

membersPersistedLengthMaximum

public final long membersPersistedLengthMaximum()

Specified by:

membersPersistedLengthMaximum in interface PersistenceTypeDefinition
