Member Function Documentation
| double ABA_Constraint::coeff | ( | ABA_VARIABLE * | v | ) | [virtual] |
- Parameters:
-
v A pointer to a variable.
- Returns:
- The coefficient of the variable v in the constraint.
Definition at line 8 of file aba_constraint.cc.
| int ABA_Constraint::genRow | ( | Active_Variables * | var, | |
| Row & | row | |||
| ) | [virtual] |
This function is declared virtual since faster constraint specific implementations might be desirable. All nonzero coefficients are added to the row format. Before we generate the coefficients we try to expand the constraint, afterwards it is compressed again.
- Returns:
- The number of nonzero elements in the row format row.
- Parameters:
-
var The variable set for which the row format should be computed. row Stores the row format after calling this function.

| double ABA_Constraint::rhs | ( | ) | [virtual] |
- Returns:
- The right hand side of the constraint.
