| class | VisibilityIterator2 |
VisibilityIterator2 iterates through one or more readonly MeasurementSets.
Public interface
The VisibilityIterator2 is a readonly iterator returning visibilities
VisibilityIterator2 provides iteration with various sort orders for one or more MSs. It has member functions to retrieve the fields commonly needed in synthesis calibration and imaging.
One should use VisBuffer to access chunks of data.
For imaging and calibration you need to access an MS in some consistent order (by field, spectralwindow, time interval etc.). This class provides that access.

| virtual void casa::vi::ViImplementation2::slurp | ( | ) | const [pure virtual] |

Slurping the column is to be considered as a work-around for the Table i/o code, which uses BucketCache and performs extremely bad for random access. Slurping is useful when iterating non-sequentially an MS or parts of an MS, it is not tested with multiple MSs.
