The following constants are used by the functions for managing parallel tasks: | | | | Constant | Description | Used by the functions |
|---|
| ptoDelayedCopyHFSQLContext | Triggers a light copy of HFSQL context during the first access to the HFSQL data. | Description of ParallelTask, variable of type ParallelTask,
ParallelTaskExecute,
ParallelTaskExecuteAfter,
ParallelTaskExecuteAfterAll
ParallelTaskExecuteAfterOne | | ptoFullCopyHFSQLContext | Triggers the immediate copy of the current HFSQL context.
Recommended, for example, if the parallel task must take into account the current positions in the files and queries of the context of the caller. | Description of ParallelTask, variable of type ParallelTask,
ParallelTaskExecute,
ParallelTaskExecuteAfter,
ParallelTaskExecuteAfterAll
ParallelTaskExecuteAfterOne | | ptoLightCopyHFSQLContext | Triggers the immediate copy of a part of the current HFSQL context.
Only the directories containing the data files in HFSQL Classic mode and/or the connections in HFSQL Client/Server mode are stored. | Description of ParallelTask, variable of type ParallelTask,
ParallelTaskExecute,
ParallelTaskExecuteAfter,
ParallelTaskExecuteAfterAll
ParallelTaskExecuteAfterOne | | ptoMainThread | Runs the task in the main thread.
Caution: This constant cannot be used to run a parallel task in the main thread from the main thread. | Description of ParallelTask, variable of type ParallelTask,
ParallelTaskExecute,
ParallelTaskExecuteAfter,
ParallelTaskExecuteAfterAll
ParallelTaskExecuteAfterOne | | ptpMaximumNumberThread | Maximum number of threads that can be run at the same time. | ParallelTaskConfigure | | ptsCanceled | Status of parallel task: The parallel task is canceled (ParallelTaskCancel). | ParallelTask variable | | ptsCancellationRequested | Status of parallel task: A cancellation request was performed on the parallel task (ParallelTaskRequestCancellation). | ParallelTask variable | | ptsCompleted | Status of parallel task: The parallel task is ended. | ParallelTask variable | | ptsExecutionInProgress | Status of parallel task: The parallel task is currently run. | ParallelTask variable | | ptsNotScheduled | Status of parallel task: The parallel task is not scheduled. | ParallelTask variable | | ptsWaitingExecution | Status of parallel task: The parallel task is waiting to be run. | ParallelTask variable | | ptsWaitingPrevious | Status of parallel task: The parallel task waits for the execution of a previous parallel task. | ParallelTask variable |
