Method Detail

from

JDOQLQuery<T> from(EntityPath<?>... sources)

Add query sources

Parameters:

sources - sources

Returns:

the current object

from

<U> JDOQLQuery<T> from(CollectionExpression<?,U> path,
                       Path<U> alias)

Add query sources

Type Parameters:

U -

Parameters:

path - source

alias - alias

Returns:

the current object

clone

JDOQLQuery<T> clone(javax.jdo.PersistenceManager persistenceManager)

Clone the state of the query for the given PersistenceManager

Parameters:

persistenceManager - persistence manager

Returns:

cloned query

addFetchGroup

JDOQLQuery<T> addFetchGroup(String fetchGroupName)

Add the fetch group to the set of active fetch groups.

Parameters:

fetchGroupName - fetch group name

Returns:

the current object

setMaxFetchDepth

JDOQLQuery<T> setMaxFetchDepth(int maxFetchDepth)

Set the maximum fetch depth when fetching. A value of 0 has no meaning and will throw a JDOUserException. A value of -1 means that no limit is placed on fetching. A positive integer will result in that number of references from the initial object to be fetched.

Parameters:

maxFetchDepth - max fetch depth

Returns:

the current object

close

void close()

Close the query and related resources

Specified by:

close in interface AutoCloseable
