Package org.hibernate

This package defines the central Hibernate APIs.


Interface Summary
Criteria Criteria is a simplified API for retrieving entities by composing Criterion objects.
EntityNameResolver Contract for resolving an entity-name from a given entity instance.
Filter Type definition of Filter.
Interceptor Allows user code to inspect and/or change property values.
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.
SessionFactory Creates Sessions.
SessionFactoryObserver Allows reaction to basic SessionFactory occurrences.
SQLQuery Allows the user to declare the types and select list injection points of all entities returned by the query.
StatelessSession A command-oriented API for performing bulk operations against a database.

A stateless session does not implement a first-level cache nor interact with any second-level cache, nor does it implement transactional write-behind or automatic dirty checking, nor do operations cascade to associated instances.
Transaction Allows the application to define units of work, while maintaining abstraction from the underlying transaction implementation (eg.

Class 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.
EmptyInterceptor An interceptor that does nothing.
EntityMode Defines the representation modes available for entities.
FetchMode Represents an association fetching strategy.
FlushMode Represents a flushing strategy.
Hibernate Provides access to the full range of Hibernate built-in types.
LockMode Instances represent a lock mode for a row of a relational database table.
ReplicationMode Represents a replication strategy.
ScrollMode Specifies the type of JDBC scrollable result set to use underneath a ScrollableResults

Exception Summary
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 Any exception that occurs inside the persistence layer or JDBC driver.
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).
PersistentObjectException Thrown when the user passes a persistent instance to a Session method that expects a transient instance.
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
SessionException Thrown when the user calls a method of a Session that is in an inappropropriate 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.
TypeMismatchException Used when a user provided type does not match the expected one
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.
