Rose::ProgressTask Class Reference

Description

RAII sub-task progress.

Pushes a new context onto the specified progress reporting object in preparation for calling an analysis that does its own progress reporting.

Use this class like this. The completion ratios are arbitrary and we've assumed that do_something, inner both take roughly the same (large) amount of time.

void outerTask(const Progress::Report &progress) {
    progress->update(Progress::Report(0.0));
    do_something(); // after this, we're 1/3 done

    {
        ProgressTask t(progress, "inner", 0.67);
        inner(progress); // progress reports named "outer.inner" going from [0..1]
    }

    progress->update(Progress::Report(0.67)); // optional since 0.67 was reported by destructor
    do_something();
}

Member Function Documentation

Progress::Ptr Rose::ProgressTask::progress ( ) const

inline

Progress object being used.

This returns one of the following values:

• If cancel has been called then return the null pointer.
• If constructed with a progress object, return that object (possibly null).
• Return the progress created by the constructor.

Definition at line 474 of file Progress.h.

void Rose::ProgressTask::cancel ( )

inline

Cancel all cleanup operations.

If called, then the destructor will do nothing other than possibly releasing a reference to the progress object supplied to or created by the constructor.
