MemoryRepository

classin packageklyn.data.memory

public class MemoryRepository<T, TId> implements Repository<T, TId>, MemoryRepositoryRegistration, MemoryIdentityLookup<T, TId>

MemoryRepository

All Implemented Interfaces: Repository, MemoryRepositoryRegistration, MemoryIdentityLookup<T, TId>

Read-only, no-tracking repository over an in-memory entity sequence.

Entity identity is obtained from the effective provider-neutral mapping: @Id, @EmbeddedId, or @IdClass. Existing lists are wrapped without copying, so constructing a repository is constant-space and queries observe the current list content. Keys are validated eagerly because the complete input is already available.

Example

import klyn.data.memory

users = MemoryRepository<User, Int>(fixtures)
active = query:
    from users user
    where user.active

Properties

Modifier and Type	Member	Description
public readonly property	entityType `entityType as Type`	Entity type exposed through MemoryConfiguration.
public readonly property	identityType `identityType as Type`	Exact identity type exposed through MemoryConfiguration.

Constructors

Modifier and Type	Member	Description
public	MemoryRepository `MemoryRepository(values as IList<T>)`	Creates a validated read-only repository.

Methods

Modifier and Type	Member	Description
public	asQuery `asQuery() as Query<T>`	Returns an immutable identity query over the repository.
public	count `count() as Long`	Returns the exact repository size.
public	countPlan `countPlan(plan as QueryPlanBase) as Long`	Counts plan results through the optimized memory plan path.
public	executePlan `executePlan(plan as QueryPlanBase) as Object`	Executes a typed plan directly over the repository snapshot.
public	existsPlan `existsPlan(plan as QueryPlanBase) as Boolean`	Tests plan existence through the optimized memory plan path.
public	findIdentity `findIdentity(id as TId) as T`	Returns one entity to the owning EntityManager, or null when absent.
public	openStream `openStream(plan as QueryPlanBase) as Object`	Opens an independent forward-only execution over the current rows.
public	planExecutionMode `planExecutionMode(plan as QueryPlanBase) as ProviderExecutionMode`	Memory plans execute through specialized local loops.
public	planWarnings `planWarnings(plan as QueryPlanBase) as IList<String>`	Memory execution introduces no implicit provider buffering.
public	providerCapabilities `providerCapabilities() as ProviderCapabilities`	Returns local-memory provider capabilities.
public	providerDomain `providerDomain() as Object`	Direct memory repositories share the local-memory execution domain.
public	providerName `providerName() as String`	Returns this provider's stable identifier.
public	providerText `providerText(plan as QueryPlanBase) as String`	Returns a redacted provider-plan description.
public	repositoryObject `repositoryObject() as Object`	Returns this concrete repository for heterogeneous configuration storage.
public	validateBeforeRead `validateBeforeRead() as Repository<T, TId>`	Revalidates every identity before reads requiring strict validation.
