Method Detail

getFactory

HibernateEntityManagerFactory getFactory()
Get access to the Hibernate extended EMF contract.

Returns:
The Hibernate EMF contract for this EM.

isTransactionInProgress

boolean isTransactionInProgress()
Provides access to whether a transaction is currently in progress.

Returns:
True if a transaction is considered currently in progress; false otherwise.

handlePersistenceException

void handlePersistenceException(PersistenceException e)
Handles marking for rollback and other such operations that need to occur depending on the type of exception being handled.

Parameters:
e - The exception being handled.

throwPersistenceException

void throwPersistenceException(PersistenceException e)
Delegates to handlePersistenceException(javax.persistence.PersistenceException) and then throws the given exception.

Parameters:
e - The exception being handled and finally thrown.

convert

RuntimeException convert(HibernateException e,
                         LockOptions lockOptions)
Converts a Hibernate-specific exception into a JPA-specified exception; note that the JPA sepcification makes use of exceptions outside its exception hierarchy, though they are all runtime exceptions.

Any appropriate/needed calls to handlePersistenceException(javax.persistence.PersistenceException) are also made.

Parameters:
e - The Hibernate excepton.
lockOptions - The lock options in effect at the time of exception (can be null)
Returns:
The JPA-specified exception

convert

RuntimeException convert(HibernateException e)
Converts a Hibernate-specific exception into a JPA-specified exception; note that the JPA sepcification makes use of exceptions outside its exception hierarchy, though they are all runtime exceptions.

Any appropriate/needed calls to handlePersistenceException(javax.persistence.PersistenceException) are also made.

Parameters:
e - The Hibernate excepton.
Returns:
The JPA-specified exception

throwPersistenceException

void throwPersistenceException(HibernateException e)
Delegates to convert(org.hibernate.HibernateException, org.hibernate.LockOptions) and then throws the given exception.

Parameters:
e - The exception being handled and finally thrown.

wrapStaleStateException

PersistenceException wrapStaleStateException(StaleStateException e)

getLockRequest

LockOptions getLockRequest(LockModeType lockModeType,
                           Map<String,Object> properties)
Convert from JPA 2 LockModeType & properties into LockOptions

Parameters:
lockModeType - is the requested lock type
properties - are the lock properties
Returns:
the LockOptions

createQuery

<T> TypedQuery<T> createQuery(String jpaqlString,
                              Class<T> resultClass,
                              Selection selection,
                              HibernateEntityManagerImplementor.Options options)
Used during "compiling" a JPA criteria query.

Type Parameters:
T - The query type
Parameters:
jpaqlString - The criteria query rendered as a JPA QL string
resultClass - The result type (the type expected in the result list)
selection - The selection(s)
options - The options to use to build the query.
Returns:
The typed query
