| Variable (int i) | |
Builds the variable corresponding to the Cartesian axis of index i. | |
| int | id () |
Returns the index of the Cartesian axis associated to this. | |
| int | compareTo (Variable v) |
Returns a negative number if this comes first than v, a zero if this equals v, a positive number if if this comes first than v. | |
An object of the class Variable represents a dimension of the space, that is one of the Cartesian axes. Variables are used as basic blocks in order to build more complex linear expressions. Each variable is identified by a non-negative integer, representing the index of the corresponding Cartesian axis (the first axis has index 0).
| parma_polyhedra_library::Variable::Variable | ( | int | i | ) | [inline] |
Builds the variable corresponding to the Cartesian axis of index i.
| RuntimeErrorException | Thrown if i is has negative value. |
