Member Function Documentation

virtual int casacore::BaseCompare::comp ( const void *  obj1,
const void *  obj2 
) const [pure virtual]

Compare two objects, and return.

  • -1 if obj1 < obj2;
  • 0 if obj1 == obj2;
  • 1 otherwise.

Implemented in casacore::ObjCompare< T >, casacore::CompareIntervalInt< T >, casacore::CompareIntervalReal< T >, casacore::CompareNoCase, and casacore::MSInterval.

virtual DataType casacore::BaseCompare::dataType (  )  const [inline, virtual]

Get the data type of a straight-forward sort comparison in ObjCompare.

It is used to test if a the faster GenSortIndirect can be used. By default it returns TpOther.

Reimplemented in casacore::ObjCompare< T >.
