isIteratedResult
public boolean isIteratedResult()
Description copied from interface:OperationHintsReturnstrueto indicate that any results of a select operation should be returned as a ResultIterator.falseis returned when the results are expected as a list.- Specified by:
isIteratedResultin interfaceOperationHints
-
nextCount
public void nextCount(Query query, int resultCount)
Description copied from interface:OperationObserverCallback method invoked after an updating query is executed.- Specified by:
nextCountin interfaceOperationObserver
-
nextBatchCount
public void nextBatchCount(Query query, int[] resultCount)
Description copied from interface:OperationObserverCallback method invoked after a batch update is executed.- Specified by:
nextBatchCountin interfaceOperationObserver
-
nextRows
public void nextRows(Query query, List<?> dataRows)
Description copied from interface:OperationObserverCallback method invoked for each processed ResultSet.- Specified by:
nextRowsin interfaceOperationObserver
-
nextRows
public void nextRows(Query q, ResultIterator<?> it)
Description copied from interface:OperationObserverCallback method invoked for each opened ResultIterator. If this observer requested results to be returned as a ResultIterator, this method is invoked instead ofOperationObserver.nextRows(Query, List).- Specified by:
nextRowsin interfaceOperationObserver
-
nextGeneratedRows
public void nextGeneratedRows(Query query, ResultIterator<?> keys, ObjectId idToUpdate)
Description copied from interface:OperationObserverCallback method invoked after each batch of generated values is read during an update.- Specified by:
nextGeneratedRowsin interfaceOperationObserver
-
nextQueryException
public void nextQueryException(Query query, Exception ex)
Description copied from interface:OperationObserverCallback method invoked on exceptions that happen during an execution of a specific query.- Specified by:
nextQueryExceptionin interfaceOperationObserver
-
nextGlobalException
public void nextGlobalException(Exception ex)
Description copied from interface:OperationObserverCallback method invoked on exceptions that are not tied to a specific query execution, such as JDBC connection exceptions, etc.- Specified by:
nextGlobalExceptionin interfaceOperationObserver
