## Package org.hibernate

This package defines the central Hibernate APIs.

See:
Description

Interface Summary
Cache | Provides an API for querying/managing the second level cache regions.
Criteria | `Criteria` is a simplified API for retrieving entities by composing `Criterion` objects.
CustomEntityDirtinessStrategy | During a flush cycle, Hibernate needs to determine which of the entities associated with a `Session`.
CustomEntityDirtinessStrategy.AttributeChecker | Responsible for identifying when attributes are dirty.
CustomEntityDirtinessStrategy.AttributeInformation | Provides `CustomEntityDirtinessStrategy.AttributeChecker` with meta information about the attributes being checked.
CustomEntityDirtinessStrategy.DirtyCheckContext | A callback to drive dirty checking.
EntityNameResolver | Contract for resolving an entity-name from a given entity instance.
Filter | Type definition of Filter.
IdentifierLoadAccess | Loads an entity by its primary identifier
Interceptor | Allows user code to inspect and/or change property values.
LobHelper | A `session's` helper for creating LOB data
NaturalIdLoadAccess | Loads an entity by its natural identifier
Query | An object-oriented representation of a Hibernate query.
ScrollableResults | A result iterator that allows moving around within the results by arbitrary increments.
Session | The main runtime interface between a Java application and Hibernate.
Session.LockRequest | Contains locking details (LockMode, Timeout and Scope).
SessionBuilder | Represents a consolidation of all session creation options into a builder style delegate.
SessionFactory | The main contract here is the creation of `Session` instances.
SessionFactory.SessionFactoryOptions |
SessionFactoryObserver | Allows reaction to basic `SessionFactory` occurrences.
SharedSessionBuilder | Specialized `SessionBuilder` with access to stuff from another session
SharedSessionContract | Contract methods shared between `Session` and `StatelessSession`
SimpleNaturalIdLoadAccess | Loads an entity by its natural identifier
SQLQuery | Represents a "native sql" query and allows the user to define certain aspects about its execution, such as: result-set value mapping (see below) Tables used via `SQLQuery.addSynchronizedQuerySpace(java.lang.String)`, `SQLQuery.addSynchronizedEntityName(java.lang.String)` and `SQLQuery.addSynchronizedEntityClass(java.lang.Class)`.
SQLQuery.FetchReturn | Allows access to further control how join fetch returns are mapped back from result sets
SQLQuery.ReturnProperty | Allows access to further control how properties within a root or join fetch are mapped back from the result set.
SQLQuery.RootReturn | Allows access to further control how root returns are mapped back from result sets
SQLQueryResultMappingBuilder | Allows programmatic access from `SQLQuery` to define how to map SQL `results` back to in-memory objects, both entities as well as scalars.
SQLQueryResultMappingBuilder.ReturnsHolder |
StatelessSession | A command-oriented API for performing bulk operations against a database.
StatelessSessionBuilder | Represents a consolidation of all stateless session creation options into a builder style delegate.
Transaction | Defines the contract for abstracting applications from the configured underlying means of transaction management.
TypeHelper | Provides access to the various `Type` instances associated with the `SessionFactory`.

Class Summary
EmptyInterceptor | An interceptor that does nothing.
Hibernate | Provides access to the full range of Hibernate built-in types.
LockOptions | Contains locking details (LockMode, Timeout and Scope).
SQLQueryResultMappingBuilder.ScalarReturn |
Version | Information about the Hibernate version.

Enum Summary
CacheMode | Controls how the session interacts with the second-level cache and query cache.
ConnectionReleaseMode | Defines the various policies by which Hibernate might release its underlying JDBC connection.
DuplicateMappingException.Type |
EntityMode | Defines the representation modes available for entities.
FetchMode | Represents an association fetching strategy.
FlushMode | Represents a flushing strategy.
LockMode | Instances represent a lock mode for a row of a relational database table.
MultiTenancyStrategy | Describes the methods for multi-tenancy understood by Hibernate.
ReplicationMode | Represents a replication strategy.
ScrollMode | Specifies the type of JDBC scrollable result set to use underneath a `ScrollableResults`

Exception Summary
AnnotationException | Annotation related exception.
AssertionFailure | Indicates failure of an assertion: a possible bug in Hibernate.
CallbackException | Should be thrown by persistent objects from `Lifecycle` or `Interceptor` callbacks.
DuplicateMappingException | Raised whenever a duplicate for a certain type occurs.
HibernateException | The base `Throwable` type for Hibernate.
InstantiationException | Thrown if Hibernate can't instantiate an entity or component class at runtime.
InvalidMappingException | Thrown when a mapping is found to be invalid.
JDBCException | Wraps an `SQLException`.
LazyInitializationException | Indicates access to unfetched data outside of a session context.
MappingException | An exception that usually occurs at configuration time, rather than runtime, as a result of something screwy in the O-R mappings.
MappingNotFoundException | Thrown when a resource for a mapping could not be found.
NonUniqueObjectException | This exception is thrown when an operation would break session-scoped identity.
NonUniqueResultException | Thrown when the application calls `Query.uniqueResult()` and the query returned more than one result.
ObjectDeletedException | Thrown when the user tries to do something illegal with a deleted object.
ObjectNotFoundException | Thrown when `Session.load()` fails to select a row with the given primary key (identifier value).
OptimisticLockException | Deprecated. Use `OptimisticEntityLockException` instead
PersistentObjectException | Thrown when the user passes a persistent instance to a `Session` method that expects a transient instance.
PessimisticLockException | Thrown when a pessimistic locking conflict occurs.
PropertyAccessException | A problem occurred accessing a property of an instance of a persistent class by reflection, or via CGLIB.
PropertyNotFoundException | Indicates that an expected getter or setter method could not be found on a class.
PropertyValueException | Thrown when the (illegal) value of a property can not be persisted.
QueryException | A problem occurred translating a Hibernate query to SQL due to invalid query syntax, etc.
QueryParameterException | Parameter invalid or not found in the query
QueryTimeoutException | Thrown when a database query timeout occurs.
ResourceClosedException | Indicates an attempt was made to use a closed resource (Session, SessionFactory, etc).
SessionException | Thrown when the user calls a method of a `Session` that is in an inappropriate state for the given call (for example, the the session is closed or disconnected).
StaleObjectStateException | A `StaleStateException` that carries information about a particular entity instance that was the source of the failure.
StaleStateException | Thrown when a version number or timestamp check failed, indicating that the `Session` contained stale data (when using long transactions with versioning).
TransactionException | Indicates that a transaction could not be begun, committed or rolled back.
TransientObjectException | Thrown when the user passes a transient instance to a `Session` method that expects a persistent instance.
TransientPropertyValueException | Thrown when a property cannot be persisted because it is an association with a transient unsaved entity instance.
TypeMismatchException | Used when a user provided type does not match the expected one
UnknownProfileException | Used to indicate a request against an unknown profile name.
UnresolvableObjectException | Thrown when Hibernate could not resolve an object by id, especially when loading an association.
WrongClassException | Thrown when `Session.load()` selects a row with the given primary key (identifier value) but the row's discriminator value specifies a subclass that is not assignable to the class requested by the user.
