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

virtual DataType casacore::BaseCompare::dataType ( ) const

inlinevirtual

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 >.
