JDO Method in javax.jdo.Query void closeAll () Close all query results associated with this Query instance, and release all resources associated with them. The query results might have iterators open on them. Iterators associated with the query results are invalidated: they return false to hasNext

JDO Method in javax.jdo.Transaction boolean getRollbackOnly () Returns the rollback-only status of the transaction. When begun, the rollback-only status is false . Either the application or the JDO implementation may set this flag using setRollbackOnly. Return: true if the transaction has been marked for rollback. Since: JDO 2.0
