Method Detail

getResultList

List<X> getResultList()

Execute a SELECT query and return the query results as a typed List.

Specified by:

getResultList in interface Query

Returns:

a list of the results

Throws:

IllegalStateException - if called for a Java Persistence query language UPDATE or DELETE statement

QueryTimeoutException - if the query execution exceeds the query timeout value set and only the statement is rolled back

TransactionRequiredException - if a lock mode other than NONE has been set and there is no transaction or the persistence context has not been joined to the transaction

PessimisticLockException - if pessimistic locking fails and the transaction is rolled back

LockTimeoutException - if pessimistic locking fails and only the statement is rolled back

PersistenceException - if the query execution exceeds the query timeout value set and the transaction is rolled back

getResultStream

default Stream<X> getResultStream()

Execute a SELECT query and return the query results as a typed java.util.stream.Stream. By default this method delegates to getResultList().stream(), however persistence provider may choose to override this method to provide additional capabilities.

Specified by:

getResultStream in interface Query

Returns:

a stream of the results

Throws:

IllegalStateException - if called for a Java Persistence query language UPDATE or DELETE statement

QueryTimeoutException - if the query execution exceeds the query timeout value set and only the statement is rolled back

TransactionRequiredException - if a lock mode other than NONE has been set and there is no transaction or the persistence context has not been joined to the transaction

PessimisticLockException - if pessimistic locking fails and the transaction is rolled back

LockTimeoutException - if pessimistic locking fails and only the statement is rolled back

PersistenceException - if the query execution exceeds the query timeout value set and the transaction is rolled back

Since:

2.2

Stream, getResultList()

getSingleResult

Specified by:

getSingleResult in interface Query

Returns:

the result

Throws:

NoResultException - if there is no result

NonUniqueResultException - if more than one result

IllegalStateException - if called for a Java Persistence query language UPDATE or DELETE statement

QueryTimeoutException - if the query execution exceeds the query timeout value set and only the statement is rolled back

setMaxResults

TypedQuery<X> setMaxResults(int maxResult)

Set the maximum number of results to retrieve.

Specified by:

setMaxResults in interface Query

Parameters:

maxResult - maximum number of results to retrieve

Returns:

the same query instance

Throws:

IllegalArgumentException - if the argument is negative

setFirstResult

TypedQuery<X> setFirstResult(int startPosition)

Set the position of the first result to retrieve.

Specified by:

setFirstResult in interface Query

Parameters:

startPosition - position of the first result, numbered from 0

Returns:

the same query instance

Throws:

IllegalArgumentException - if the argument is negative

setHint

TypedQuery<X> setHint(String hintName,
                      Object value)

Set a query property or hint. The hints elements may be used to specify query properties and hints. Properties defined by this specification must be observed by the provider. Vendor-specific hints that are not recognized by a provider must be silently ignored. Portable applications should not rely on the standard timeout hint. Depending on the database in use and the locking mechanisms used by the provider, this hint may or may not be observed.

Specified by:

setHint in interface Query

Parameters:

hintName - name of property or hint

value - value for the property or hint

Returns:

the same query instance

Throws:

IllegalArgumentException - if the second argument is not valid for the implementation

setParameter

                               T value)

Bind the value of a Parameter object.

Specified by:
