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

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

Entity identity is obtained from the unique property annotated with @Id. 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	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.
