Method Detail

createQuery

public org.hibernate.Query createQuery(Expression<?>... args)

list

public List<Object[]> list(Expression<?>[] 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 AbstractHibernateSQLQuery<Q>>

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 AbstractHibernateSQLQuery<Q>>

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)

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(String queryString)

reset

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 and your own projection methods.

Type Parameters:

RT - return type

Returns:

the result or null for an empty result

setCacheable

public Q setCacheable(boolean cacheable)

Enable caching of this query result set.

Parameters:

cacheable - Should the query results be cacheable?

setCacheRegion

public Q setCacheRegion(String cacheRegion)

Set the name of the cache region.

Parameters:

cacheRegion - the name of a query cache region, or null for the default query cache

setFetchSize

public Q setFetchSize(int fetchSize)

Set a fetch size for the underlying JDBC query.

Parameters:

fetchSize - the fetch size

setReadOnly

public Q setReadOnly(boolean readOnly)

Entities retrieved by this query will be loaded in a read-only mode where Hibernate will never dirty-check them or make changes persistent.
