Detailed Description
Basic Constraints : Base Class to define constraint-schema
Definition at line 24 of file cons_obj.h.
Constructor & Destructor Documentation
| cons_obj::cons_obj | ( | cons_sense | s, | |
| double | rhs | |||
| ) |
creates a new instance of a constraint-schema and instantiates the basic fields of the basic constraint.
Definition at line 10 of file cons_obj.cc.
| cons_obj::cons_obj | ( | ) |
creates a new instance of a constraint-schema and instantiates the basic fields with the default values.
Definition at line 18 of file cons_obj.cc.
Member Function Documentation
| virtual void SCIL::cons_obj::non_zero_entries | ( | row & | r | ) | [inline, virtual] |
returns the non-zero entries of the basic constraint. the default implementation returns no non-zeros. A user defined constraint-schema should redefine this function.
