void Isis::WorkOrder::asyncRedo ( )
protectedvirtualinherited

This method is designed to be implemented by children work orders.

The order of execution for redo is: syncRedo() - GUI thread asyncRedo() - Pooled thread* postSyncRedo() - GUI thread

State can be read from the parent WorkOrder class and from state set in syncRedo() while in this method. You can set state to be used in postSyncRedo() safely. Please be wary of creating QObjects inside of this method because they will associated with the pooled thread and must be moved back to the GUI thread with QObject::moveToThread(). This method is never executed in the GUI thread. You can update progress by calling setProgressRange() and setProgressValue(). Please do not manipulate any GUI objects here.

Reimplemented in Isis::ImportImagesWorkOrder, Isis::ImportControlNetWorkOrder, Isis::ExportImagesWorkOrder, and Isis::ExportControlNetWorkOrder.

void Isis::WorkOrder::asyncUndo ( )
protectedvirtualinherited

This method is designed to be implemented by children work orders.

The order of execution for undo is: syncUndo() - GUI thread asyncUndo() - Pooled thread* postSyncUndo() - GUI thread

State can be read from the parent WorkOrder class and from state set in syncUndo() while in this method. You can set state to be used in postSyncUndo() safely. Please be wary of deleting QObjects inside of this method because they will cause unpredictable crashes. This method is never executed in the GUI thread. You can update progress by calling setProgressRange() and setProgressValue(). Please do not manipulate any GUI objects here.

bool Isis::ImageFileListViewWorkOrder::execute ( )
virtual

The (child) implementation of this method should prompt the user/gather state by any means necessary.

This method is designed to be implemented by children work orders, but they need to call this version inside of their execute (at the beginning).

Prompts for file names, questions, warnings, etc.. should be done here.

Once the work order has enough data to execute, this method needs to set the state in the parent (this) WorkOrder class. Call setData(ImageList), setInternalData(QStringList), etc... with all of the data/state necessary to perform the work order. This could be a list of file names, an ImageList of images you're viewing, or really anything else.

Finally, the actual work needs done in *Redo(), using only state (data) stored by the parent (this) WorkOrder class. You do not have to call *Redo() - this is done for you by WorkOrder::redo(). WorkOrder::redo() is called from Project::addToProject() when the workOrder is pushed onto the undo stack.

We do it this way to ensure saving/restoring from history can be done automatically/simply and implemented only once per data type. This also gives us full undo/redo functionality.

Returns
False if this operation should be cancelled (the user clicked cancel, the operation turns out to be impossible, etc). This prevents the work order from making it into the history and redo will never be called.

The order of execution for work orders is: execute() - GUI thread, can ask user for input* syncRedo() - GUI thread, should not prompt the user for input asyncRedo() - Pooled thread postSyncRedo() - GUI thread

syncUndo() - GUI thread, always called after redo finishes asyncUndo() - Pooled thread postSyncUndo() - GUI thread

syncRedo() - GUI thread asyncRedo() - Pooled thread postSyncRedo() - GUI thread

and so on...

State should only be set in the parent WorkOrder class in this method. You can set arbitrary state using setInternalData(). This method is always executed in the GUI thread and is the only place to ask the user questions.

bool Isis::ImageFileListViewWorkOrder::isExecutable ( ImageList images)
virtual

Re-implement this method if your work order utilizes images for data in order to operate.

For example, "Footprint2DViewWorkOrder" works sometimes on images - the logic in side of Footprint2DViewWorkOrder::isExecutable(ImageList) determines whethere or not a user is prompted with this work order as a possibility.

Parameters
imagesAn image list that this work order should execute on

void Isis::WorkOrder::postSyncRedo ( )

This method is designed to be implemented by children work orders.

The order of execution for redo is: syncRedo() - GUI thread asyncRedo() - Pooled thread postSyncRedo() - GUI thread*

State can be read from the parent WorkOrder class and from state set in either syncRedo() or asyncRedo() while in this method. You can not set state to be used in any of the undo code safely. This method is always executed in the GUI thread and has no progress.

void Isis::WorkOrder::setCreatesCleanState ( bool  createsCleanState)
protectedinherited

Declare that this work order is saving the project.

This makes the work order not appear in the undo stack (cannot undo/redo), and instead is marked as a 'clean' state of the project. The QUndoCommand undo/redo will never be called. The default for createsCleanState is false.

Parameters
createsCleanStateTrue if this work order is going to save the project to disk
