Member Function Documentation

ProcessingResult casa::vpf::SplitterVp::doProcessingImpl	(	ProcessingType	processingType,
		VpData &	inputData,
		const SubchunkIndex &	subChunkIndex
	)

protectedvirtual

Requests processing of the provided (possibly empty) input data.

This is called on each subchunk (then inputData will be nonempty) and at the end of a chunk and the end of the entire data set. These last two call types allow the VP to output any data that it might have been accumulating across multiple subchunks, etc.

Implements casa::vpf::VisibilityProcessor.

void casa::vpf::SplitterVp::validateImpl ( )

protectedvirtual

Called to allow the node to validate its initial state.

An casacore::AipsError should be thrown if this node decides that it is invalid.

Implements casa::vpf::VisibilityProcessor.
