Add ITK/VTK plugin watcher utility classes #13
Description
In order for CLI to report progress, the following output is the standard:
<filter-start>
<filter-name>...</filter-name>
...
</filter-start>
<filter-progress>
...
There is in Slicer (Base/CLI) some utility classes that observe ITK and VTK filters to automatically generate such output.
Such classes should be moved in SlicerExecutionModel as conveniency (and be enabled only if ITK_DIR or VTK_DIR are passed).
A generic progress watcher (whose itkPluginFilterWatcher and vtkPluginFilterWatcher should derive from) should also be added.
class SEMProgressWatcher
{
public:
SEMProgressWatcher(const char* name, const char* comment = 0, ModuleProcessInformation* inf = 0, double fraction = 1.0, double start = 0.0);
virtual void Start();
virtual void SetProgress(double progress);
virtual void End();
virtual double GetProgress();
protected:
void ReportStart();
void ReportEnd();
void ReportProgress();
};
class itkPluginFilterWatcher: public itkSimpleFilterWatcher, SEMProgressWatcher
{
...
};
class vtkPluginFilterWatcher: public SEMProgressWatcher
{
...
};
