Behaviour of the progress Manager

The progressmanager is manages a collection of progresses. This are usually time consuming background tasks. Each registred progress should report its progress through the IProgress<ProgressReport> interface. Depending on the state of the progress the folling items shoud be submitted:

State	Progress	Title	Description
Running	x	x	optional
Paused	x	x	optional
Intermediate		x	optional
Faultet		x	optional
Finished		x	optional

To determinate the aggregated state following Algorithm is used.

// Let data store all running progresses
IEnumerable<ProgressReport> data;

ProgressStates state;
double progress;

if(_progresses.Any(p => p.State == ProgressStates.Running))
{
    state = ProgressStates.Running;
    progress = _progresses.Where(p => p.State == ProgressStates.Running).Average(p => p.Progress);

    return;
}

if (_progresses.Any(p => p.State == ProgressStates.Paused))
{
    state = ProgressStates.Paused;
    progress = _progresses.Where(p => p.State == ProgressStates.Paused).Average(p => p.Progress);

    return;
}

if (_progresses.Any(p => p.State == ProgressStates.Intermediate))
{
    state = ProgressStates.Intermediate;              

    return;
}

if (_progresses.Any(p => p.State == ProgressStates.Faultet))
{
    state = ProgressStates.Faultet;

    return;
}

if (_progresses.Any(p => p.State == ProgressStates.Finished))
{
    state = ProgressStates.Finished;

    return;
}
