[vtkusers] CONTINUE_EXECUTING with vtkinformation

[Biddiscombe, John A.]

did you add the vector you want to pass upstream to the KEYS_TO_COPY vector. My memory is hazy, but what you are trying to do ought to work.

Hello,

I have a source (home made reader) that is capable of generate data depending on some options.
I like to  control theses options using a filter way down in the pipeline. This means that I would like to send a vtkinformation upstream in the pipeline and also iterate for different values of this options. Something like the TemporalStatistics filter but not over time.

Till now, I tried to use the vtkStreamingDemandDrivenPipeline::CONTINUE_EXECUTING information (in the filter) to iterate over the data. My filter is re-executed but my source get executed only once.

Also tried to set a vtkInformationDoubleVectorKey to the inputVector in the RequestUpdateExtent() of my filter with some data but this information is never passed upstream.

Is this possible??? or we can do this only for time.

Thanks for all
Felipe
