Constructor & Destructor Documentation

casa::VisBufferAsync::~VisBufferAsync ( )

VisBufferAsync (const VisBuffer& vb);.

casa::VisBufferAsync::VisBufferAsync ( ) [protected]

The constructors are not public because creation should be performed by a factory object (e.g., VisBufferAutoPtr).

The use of a factory makes it possible to fine tune at run time whether a VisBuffer or a VisBufferAsync is created.

Presently this fills antenna, array, field and spectralWindow ids, time, frequency and number of rows. if dirDependent is set to False the expensive direction dependent calculation of parallactic or direction of antenna from pointing table is avoided Add more as needed.
