static

virtual casacore::Float casa::DDFunc::map ( const casacore::Cube< casacore::Complex > &  vis, casacore::uInt  ich, casacore::uInt  irow  ) const

virtual

Maps a slice of visibilities at (*,ich,irow) from the given viscube into a the derived value.

Implements casa::DDMapper.

Reimplemented in casa::DDDiffFunc, casa::DDFuncDiff, casa::DDFuncSum, and casa::DDSumFunc.

static casacore::Float casa::DDFunc::real ( const casacore::Complex &  )

static

Define these functions, because using std::real/imag in getFunction matches multiple functions.

virtual casacore::Bool casa::DDFunc::reset ( const casacore::Vector< casacore::Int > &  corr )

virtual

Given a vector of correlation types, recomputes internal indices.

returns true if all indices were found successfully.

Implements casa::DDMapper.

Reimplemented in casa::DDSumFunc.
