Detailed Description

albaMTime - record modification timestamp.

albaMTime records a unique time stamp when the method Modified() is called. This time is guaranteed to be monotonically increasing. If ALBA is build with VTK compilation enabled (ALBA_USE_VTK) this object uses a vtkTimeStamp as counter to have a unique time stamp against the two libraries.

Todo:

• fix the InterlockedIncrement - which was temporary commented out (sil)

Modified()

void albaMTime::Modified

(

)

Update this object modification time.

The modification time is just a monotonically increasing unsigned long integer. It is possible for this number to wrap around back to zero. This should only happen for processes that have been running for a very long time, while constantly changing objects within the program. When this does occur, the typical consequence should be that some filters will update themselves when really they don't need to.
