Detailed Description

Provide Undo/redo abilities, serialization, and history for an operation.

This class should be used for operations that affect a Project and need to provide history and/or undo/redo capabilities, and the ability for the project to guarantee a good state on disk. It follows the Command Pattern using Qt's QUndoCommand framework. Not all actions require WorkOrders - many of the actions performed in the various widgets may not use WorkOrders.

The order of execution for work orders is: setupExecution() - GUI thread, can ask user for input execute() - run on either the GUI thread or a non-GUI thread as specified by the m_isSynchronous flag postExecution() - perform any cleanup after execute.

undoExecution() - run on either the GUI thread or a non-GUI thread as specified by the m_isSynchronous flag postUndoExecution() - perform any cleanup after undoExecution()

** Adding a new Workorder **

The WorkOrder will need to be determined to be either synchronous/asynchronous and whether it is undoable. These are decisions determined by the use case. Asynchronous WorkOrders will not block the GUI thread while running and are typically used for long-running operations. Note that WorkOrders are not reentrant - a new one is created for each action.

The constructor for the WorkOrder must set m_isUndoable and m_isSynchronous to the appropriate values. The constructor must call the base WorkOrder constructor. The default is synchronous and undoable. If an import WorkOrder is being implemented the import must be some type of object and implement certain slots.

All information required to execute the WorkOrder should be saved in the WorkOrder in the setupExecution() method. Since WorkOrders may be serialized and may run on non-GUI threads there are restrictions on how the WorkOrder may save state. To allow serialization the WorkOrders must save state to the base WorkOrder class using WorkOrder::setInternalData() in the following calls: setupExecution(), postExecution(), postUndoExecution(). Workorders may use member variables to pass data between the execute() and postExecution() methods and also between the undoExecution() and undoPostExecution() methods since serialization can not happen between these calls. For asynchronous WorkOrders the execute()/postExecution() and undoExecution()/undoPostExecution() methods are on different threads so any allocated memory moved between the non-GUI and GUI threads between methods.

Serialization is handled by the base WorkOrder class. Since all state is saved into the base class using setInternalData() the derived WorkOrders do not contain any data that needs to be serialized. The times when WorkOrders are allowed to use member variables are periods when the WorkOrder can not be serialized.

There are 5 key methods in the flow of the WorkOrder as shown in the WorkOrder Flow diagram below.

setupExecution The setupExecution() method gathers all required information to run the WorkOrder but does not execute it. The gathered information is stored in the WorkOrder. SetupExecution() is optional but typically required. It can bring up GUI elements to prompt the user for any necessary information. SetupExecution() is not called when a WorkOrder is redone.

execute execute() needs to be implemented perform the WorkOrder. All information neccessary to run the WorkOrder should already be stored in the WorkOrder. The data necessary for the WorkOrder can be retrieved via internalData() Execute() can not use any GUI elements. Each time a WorkOrder is redone execute() is called to redo the WorkOrder.

For synchronous WorkOrders the execute() method runs on the GUI thread and there are no special requirements on object ownership.

For asynchronous WorkOrders any memory allocations that aren't deallocated within execute() will need to be moved to the GUI thread.

See also
ImportImagesWorkOrder::execute for an example of an asynchronous WorkOrder that allocates memory. setProgressValue() can be used to update the progress bar in the GUI. Any member variables being accessed by an asynchronous workorder will need to have a QMutex locker so they can be thread safe

postExecution postExecution() runs on the GUI thread so it should not perform any long running operations. It is intended for any cleanup or GUI updates after execute(). Typically it would only be needed for asynchronous WorkOrders where they need to update the GUI and do cleanup. It is not required to implement this method.

undoExecution undoExecution() is only required for undoable WorkOrders. undoExecution() should undo the effects of the execute() only using state stored in the WorkOrder. It will run on the GUI thread if synchronous or a non-GUI thread if asynchronous. The same restrictions as execute() apply to this method.

postUndoExecution() This is not required. If needed, it should perform any cleanup after undoExecution(). postUndoExecution() has the same restrictions as postExecution().

Other methods the WorkOrder may need to implement are:

isExecutable(<various type>) IsExecutable() determines if the WorkOrder should show up in the context menus (this has no bearing on how the main menu is populated). Note that isExecutable will need to be implemented for each type of parameter this WorkOrder should show in the context menu.

dependsOn This is currently not implemented properly for most WorkOrders. In theory this should determine if the workOrder parameter passed in must be completed prior to this workOrder completing. Most current WorkOrders just check if the WorkOrder parameter is the same type.

setCreatesCleanState This is used to indicate the WorkOrder has set the state back to an unchanged state from which the project was originally opened. This is used by open, save, and close project WorkOrders. Unlikely to be needed by other WorkOrders. This can needs to be set to false to be able to have an undoable workorder

setModifiesDiskState WorkOrders should call this to indicate they modify the disk state, this should be set to true to be able to have an undoable workorder. The WorkOrder should implement the undoExecution method if this is set to true.

◆ bestText()

QString Isis::WorkOrder::bestText ( ) const

Generate unique action names We don't use action text anymore because Directory likes to rename our actions.

It converts a set of actions that have the same text, like Zoom Fit, to be in a menu named Zoom Fit with items that name their widgets. Widget names are unhelpful as a description of the action.

Directory::restructureActions
Returns
QString A textual description of the action.

◆ createsCleanState()

bool Isis::WorkOrder::createsCleanState ( ) const

Returns the CleanState status (whether the Project has been saved to disk or not).

If this is set to true the work order will avoid being put on the undo stack, meaning it will not be undoable. It will also set the undo stack to a clean state, by doing this it makes all previous workorders done before the save to be no longer undoable.

Returns
Returns True if the Project has been saved to disk. False if it has not.

◆ execute

void Isis::WorkOrder::execute ( )
virtualslot

Execute the workorder.

Execute() does the actual work in the work order. All necessary data for the execution (and undo) of the workorder should have been saved in the workorder prior to execute(). Execute() is also called to redo a workorder for redoable workorders. If the workorder is a synchrounous workorder the workorder will be run on the GUI thread, otherwise it will be queued and run on a separate thread.

For Synchronous workorders: State should only be read from the parent WorkOrder class in this method. You can set state to postExecution() safely. This method is always executed in the GUI thread.

For asynchronous workorders: State can be read from the parent WorkOrder class while in this method. You can set state to be used in postExecution() 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(). You can update progress by calling setProgressRange() and setProgressValue(). Do not manipulate any GUI objects here.

◆ setupExecution

bool Isis::WorkOrder::setupExecution ( )
virtualslot

This sets up the state for the work order.

Child should implement this to get user input.

This method is designed to be implemented by children work orders, but they need to call the base class setupExecution (at the beginning).

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

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

If this method returns false the workorder will be cancelled and will not be executed.

Returns
bool Returns True upon successful preparation of the WorkOrder, 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 executing and it will not be entered into the history.

◆ undoExecution()

void Isis::WorkOrder::undoExecution ( )
protectedvirtual

Execute the steps necessary to undo this workorder.

The workorder should have all state necessary to undo itself stored in the workorder.

For synchronous workorders: State should only be read from the parent WorkOrder class in this method. You can set state to be used in postUndoExecution() safely. This method is always executed in the GUI thread and has no progress.

For Asynchronous workorders: State can be read from the parent WorkOrder class 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(). Do not manipulate any GUI objects here.
