Detailed Description

VBRemappers remap VisBuffers.

Intended use:

Public interface

Prerequisite

• VisBuffer
• SubMS

Etymology

VBRemappers remap VisBuffers.

Synopsis

When selected parts of an casacore::MS are written to a new casacore::MS, it may be necessary to remap metadata indices like Field ID, DDID, ObservationID, etc..

Example

DDIDs 1, 4, and 7, and field ID 3 is selected. They should become 0, 1, and 2, and 0, in the output.

casacore::Bool casa::VBRemapper::remap	(	VisBuffer &	vb,

Remaps vb and returns its success value.

casacore::Bool casa::VBRemapper::remapScalar ( casacore::Int &  colref, const std::map< casacore::Int, casacore::Int > &  mapper  ) const

Remaps col using mapper.

Returns false if col has a value that is not in mapper's keys (those values are left unchanged), true otherwise.
