[Paraview-developers] C++ Plugin

[Mathieu Westphal]

Hello

Only the pipeline can request an execution of a filter or in your case an
input reader.
What i would do in your situation would be a trick with animation.

Your reader could inform the pipeline it has two timesteps, and this way,
when the pepile execute the animation in a loop, your reader would be
always reexecuted, allowing you to reload any available new data.

Regards,

Mathieu Westphal
