Method Detail

typeId

long typeId()

The biuniquely associated id value identifying a type description.

Specified by:

typeId in interface PersistenceTypeIdentity

Specified by:

typeId in interface PersistenceTypeIdOwner

Specified by:

typeId in interface PersistenceTypeLink

typeName

String typeName()

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

Specified by:

typeName in interface PersistenceTypeDescription

Specified by:

typeName in interface PersistenceTypeIdentity

type

Class<?> type()

Specified by:

type in interface PersistenceTypeLink

runtimeTypeName

default String runtimeTypeName()

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 type() reference.

Returns:

the name of the corresponding runtime type

allMembers

one.microstream.collections.types.XGettingEnum<? extends PersistenceTypeDefinitionMember> allMembers()

Specified by:

allMembers in interface PersistenceTypeDescription

instanceMembers

one.microstream.collections.types.XGettingEnum<? extends PersistenceTypeDefinitionMember> instanceMembers()

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 PersistenceTypeDescription

hasPersistedReferences

boolean hasPersistedReferences()

membersPersistedLengthMinimum

long membersPersistedLengthMinimum()

membersPersistedLengthMaximum

long membersPersistedLengthMaximum()

hasPersistedVariableLength

default boolean hasPersistedVariableLength()

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)

Returns:

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

isPrimitiveType

boolean isPrimitiveType()

hasVaryingPersistedLengthInstances

boolean hasVaryingPersistedLengthInstances()

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 hasVaryingPersistedLengthInstances()

Returns:

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

toRuntimeTypeIdentifier

default String toRuntimeTypeIdentifier()

determineVariableLength

static boolean determineVariableLength(one.microstream.collections.types.XGettingSequence<? extends PersistenceTypeDescriptionMember> members)

determineIsPrimitive

static boolean determineIsPrimitive(one.microstream.collections.types.XGettingSequence<? extends PersistenceTypeDescriptionMember> allMembers)
