Constructor & Destructor Documentation

◆ ms_progress_info()

ms_progress_info	(	const std::string &	description,
		size_t	total
	)

Constructor.

Creates a new ms_progress_info object with the specified description and total number of items

Parameters

description	The task description associated with the generated ms_progress_info object
total	The total number of jobs the task will complete

◆ ~ms_progress_info()

~ms_progress_info ( )

Destructor.

The desctrutor deletes all subtasks that it has created

If a subtask has been created by calling addSubtask(const std::string & description, size_t) then the object will be deleted here by the parent object.

If an ms_progress_info object was created separately, and then added as a subtask, by calling: addSubtask(const ms_progress_info *), then it won't be deleted in this destructor. It's up to the code that created it to perform the deletion after any object(s) it was added to have been deleted.

Member Function Documentation

◆ getDescription()

const std::string & getDescription ( ) const

Returns the task description.

Returns: The task description

◆ getNumberOfSubtasks()

int getNumberOfSubtasks ( ) const

Returns the total number of child ms_progress_info objects associated directly with the ms_progress_info instance.

Only the number of direct child items is returned.

Returns: The number of child ms_progress_info objects

◆ getProgress()

size_t getProgress ( ) const

Returns the number of work items currently completed by the process running the task.

See also: getTotal()

Returns: The number of items the task has completed.

◆ getStatus()

ms_progress_info::STATUS getStatus ( ) const

Gets the current ms_progress_info::STATUS associated with the task.

Returns: The current status of the task associated with the ms_progress_info object

◆ getSubtaskProgress()

const ms_progress_info * getSubtaskProgress ( int index ) const

Returns the child ms_progress_info object at the specified index.

See also: getNumberOfSubtasks()

Parameters

index The index of the subtask to return. Must be in the range 1 .. getNumberOfSubtasks()

Returns: The ms_progress_info object at the specified index, or NULL is the passed value of index is invalid.

◆ getTotal()

size_t getTotal ( ) const

Returns the total number of work items the task is expected to complete.

See also: getProgress()

Returns: The total number of items the task is expected to complete

◆ setBreak()

void setBreak ( ) const

Sends a break/cancel request to this and all child ms_progress_info tasks.

Use from the client code to request that a long running process is cancelled. It is the responsibility of the process running the task to honour the break request.
