Method Detail

createQuery

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

list

public java.util.List<Tuple> 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> java.util.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<Tuple> 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> expr)

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 SearchResults<Tuple> listResults(Expression<?>... args)

Description copied from interface: Projectable

list the results for the given projection

Returns:

listResults

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

Description copied from interface: Projectable

list the results for the given projection

Returns:

logQuery

protected void logQuery(java.lang.String queryString)

reset

uniqueResult

public Tuple uniqueResult(Expression<?>... args)

Description copied from interface: Projectable

return a unique result for the given projection or null if no result is found

There is some ambiguity for missing results and null valued results, for disambiguation use the list or iterate methods instead.
