Detailed Description

VBRemappers remap VisBuffers.

Intended use:

Public interface

Prerequisite

Etymology

VBRemappers remap VisBuffers.

Synopsis

When selected parts of an MS are written to a new 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.

Bool casa::VBRemapper::remap	(	VisBuffer &	vb,
		const Bool	squawk = `True`
	)			const

Remaps vb and returns its success value.

Bool casa::VBRemapper::remapScalar	(	Int &	colref,
		const std::map< Int, Int > &	mapper
	)			const `[protected]`

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.
