Method Detail

createQuery

public javax.persistence.Query createQuery(Expression<?>... args)

list

public List<Object[]> list(Expression<?>[] args)

Description copied from interface: Projectable

list the results for the given projection An empty list is returned for no results.

Specified by:

list in interface Projectable

Overrides:

list in class ProjectableQuery<Q extends AbstractJPASQLQuery<Q> & Query>

Returns:

list

public <RT> List<RT> list(Expression<RT> projection)

Description copied from interface: Projectable

list the results for the given projection An empty list is returned for no results.

Specified by:

list in interface Projectable

Overrides:

list in class ProjectableQuery<Q extends AbstractJPASQLQuery<Q> & Query>

Type Parameters:

RT - generic type of the List

Returns:

a List over the projection

iterate

public com.mysema.commons.lang.CloseableIterator<Object[]> iterate(Expression<?>[] args)

Description copied from interface: Projectable

iterate over the results for the given projection

Returns:

iterate

public <RT> com.mysema.commons.lang.CloseableIterator<RT> iterate(Expression<RT> projection)

Description copied from interface: Projectable

iterate over the results for the given projection

Type Parameters:

RT - generic type of the Iterator

Returns:

an Iterator over the projection

listResults

public <RT> SearchResults<RT> listResults(Expression<RT> projection)

Description copied from interface: Projectable

list the results for the given projection

Returns:
