klyn.data - Klyn API

Interfaces

MappingRegistration - Type-erased registration boundary for heterogeneous entity mappings.
ProviderConfiguration - Provider-neutral configuration marker used by EntityManagerFactory.
QueryStream - Sequential, forward-only query result stream.
Queryable - Typed, lazy source accepted by a native KQL from clause.
Repository - Provider-neutral, keyed entity source.

Classes

EntityManager - Non-thread-safe persistence context for queries and entity lifecycle.
EntityManagerFactory - Thread-safe factory for short-lived EntityManager instances.
EntityModel - Immutable snapshot of every entity mapped by an EntityManagerFactory.
EntityTransaction - Transaction state owned by one EntityManager.
MappingDescriptor - Immutable, statically typed base for provider entity mappings.
MappingRegistry - Immutable registry of heterogeneous, statically typed entity mappings.
Page - Materialized page with an exact total count.
PageRequest - Immutable zero-based paging request.
Parameter - Immutable descriptor for one explicitly late-bound KQL parameter.
Query - Immutable, lazy and re-executable typed KQL query.
QueryExplanation - Immutable diagnostic description of a compiled query and provider plan.
SchemaManager - Thread-safe facade for physical schema creation, inspection and validation.
SchemaOperation - Immutable provider schema operation contained in a SchemaPlan.
SchemaPlan - Immutable, provider-neutral plan that reconciles mappings and physical data.
Slice - Materialized page window that avoids an exact total-count operation.

Enums

FlushMode - Controls when an EntityManager synchronizes pending changes.
SchemaOperationKind - Canonical kind of one physical schema change.

Exceptions

ConcurrentQueryAccessException - Reports forbidden concurrent use of a sequential query resource.

QueryCancellationException - Reports explicit cancellation of a running query.
QueryException - Base class for KQL translation and execution failures.
QueryTimeoutException - Reports expiration of a query execution deadline.
QueryTranslationException - Reports a KQL operation that cannot be translated canonically.
RollbackException - Reports failure or mandatory rollback during commit.
SchemaException - Base exception for schema discovery, planning and application failures.
SchemaExecutionException - Reports a provider failure while applying a schema plan.
SchemaValidationException - Reports that physical provider structures do not match mapped entities.
TransactionException - Base class for Klyn Entity Framework transaction failures.
TransactionRequiredException - Reports an operation that requires an active transaction.
UnboundParameterException - Reports one or more explicit Parameter values missing at execution.
UnloadedRelationshipException - Reports access to a relationship that was not explicitly loaded.
UnsupportedMappingException - Reports mapping metadata unsupported by the selected provider.
