Default constructor - useful only to assign another iterator later

VisibilityIteratorImpl2 ();

Construct from an casacore::MS and a casacore::Block of casacore::MS column enums specifying the iteration order. If no order is specified, it uses the default sort order of MSIter, which is not necessarily the raw order of ms! The default ordering is ARRAY_ID, FIELD_ID, DATA_DESC_ID, and TIME, but check MSIter.h to be sure. These columns will be added first if they are not specified.

An optional timeInterval (in seconds) can be given to iterate through chunks of time. The default interval of 0 groups all times together. Every 'chunk' of data contains all data within a certain time interval and with identical values of the other iteration columns (e.g. DATA_DESC_ID and FIELD_ID). Using selectChannel (), a number of groups of channels can be requested. At present the channel group iteration will always occur before the interval iteration. VisibilityIteratorImpl (const casacore::MeasurementSet & ms, const casacore::Block<casacore::Int> & sortColumns, casacore::Double timeInterval = 0);

Same as above, but with the option of using the raw order of ms (addDefaultSortCols=false). VisibilityIteratorImpl (const casacore::MeasurementSet & ms, const casacore::Block<casacore::Int> & sortColumns, const casacore::Bool addDefaultSortCols, casacore::Double timeInterval = 0);

Same as previous constructors, but with multiple MSs to iterate over. VisibilityIteratorImpl (const casacore::Block<casacore::MeasurementSet> & mss, const casacore::Block<casacore::Int> & sortColumns, casacore::Double timeInterval = 0);
