Detailed Description

Intended use:

Public interface

Prerequisite

Etymology

VisBufferImpl is a buffer for visibility data

Synopsis

This class contains 'one iteration' of the ViImplementation2 It is a modifiable buffer of values to which calibration and averaging can be applied. This allows processing of the data in larger blocks, avoiding some overheads for processing per visibility point or spectrum.

See MeasurementEquations for more details on how the VisBufferImpl is to be used.

When the user intends to allow asynchronous I/O they will need to use the VisBufferImplAsync and VisBufferImplAsyncWrapper classes; these are publicly derived from VisBufferImpl. Normally, the user should not explicitly use these classes but should use the helper class VisBufferImplAutoPtr which will ensure that the appropriate class is used.
