#include <VisBuffer.h>
Inheritance diagram for casa::VisBuffer:
Part of API
VisBuffer is a buffer for visibility data
This class contains 'one iteration' of the VisibilityIterator 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 VisBuffer is to be used.

| Vector<Int> casa::VisBuffer::vecIntRange | ( | const MSCalEnums::colDef & | calEnum | ) | const |
Utility functions to provide coordinate or column ranges of the data in the VisBuffer.
Flagging is applied before computing the ranges.
Generic accessor to column ranges of integer type, as specified by enumerations defined in class MSCalEnums. Throws an exception if the enum is not for a recognized integer column.
| Vector<Int> casa::VisBuffer::antIdRange | ( | ) | const |
Antenna id.
