template<typename inputType >
int	checkEmptyMPIInput (inputType *input)
	This method tests whether the input is a nullptr. If the computation is being done on multiple processes, it is possible that the domain of one process or more is empty, but not others, therefore in that particular case the rest of the filter will not be computed but an error message will not be sent.

Detailed Description

TTK VTK-filter for the computation of persistence curves.

Author: Guillaume Favelier guill.nosp@m.aume.nosp@m..fave.nosp@m.lier.nosp@m.@lip6.nosp@m..fr; Pierre Guillou pierr.nosp@m.e.gu.nosp@m.illou.nosp@m.@lip.nosp@m.6.fr

Date: September 2016.

This filter takes a persistence diagram as input and computes the number of pairs as a function of persistence (i.e. the number of pairs whose persistence is higher than a threshold).

These curves provide useful visual clues in order to fine-tune persistence simplification thresholds.

Parameters

Input	Input Persistence Diagram as computed by the ttkPersistenceDiagram module
Output0	Table giving the number of persistent minimum-saddle pairs as a function of persistence (vtkTable)
Output1	Table giving the number of persistent saddle-saddle pairs as a function of persistence (vtkTable)
Output2	Table giving the number of persistent saddle-maximum pairs as a function of persistence (vtkTable)
Output3	Table giving the number of all persistent pairs as a function of persistence (vtkTable)

This filter can be used as any other VTK filter (for instance, by using the sequence of calls SetInputData(), Update(), GetOutput()).

See the related ParaView example state files for usage examples within a VTK pipeline.
