# IndicatorDescription Class

An indicator constraint. Note that an indicator constraint does not have a direct representation in Xpress. Instead an indicator constraint comprises of 1. a row/inequality, 2. an indicator variable, 3. a flag that says whether the constraint is active when the variable is 1 or 0. The last two pieces of information are stored and modified along with a row. Consequently, submitting an instance of this class to AddConstraint() will - assume that the indicator variable already exists, - create a new row, - set flag and variable on that row according to the information stored in this instance. The name property of this constraint applies to the row that is associated with this Constraint (and that will be created when this instance is submitted to AddConstraints()). Instances of this class describe a constraint that has not yet been added but can be added using XpressProblem.AddConstraint(). Users should usually not have to deal with this class explicitly.
