// .NAME vtkPVTemporalDataInformation
// .SECTION Description
// vtkPVTemporalDataInformation is used to gather data information over time.
// This information provided by this class is a sub-set of vtkPVDataInformation
// and hence this is not directly a subclass of vtkPVDataInformation. It
// internally uses vtkPVDataInformation to collect information about each
// timestep.

// Port number controls which output port the information is gathered from.
// This is only applicable when the vtkObject from which the information being
// gathered is a vtkAlgorithm. Set it to -1(default), to return the classname
// of the vtkAlgorithm itself.
// This is the only parameter that can be set on the client-side before
// gathering the information.
