.NET API - GRBGenConstr#

GRBGenConstr#

Gurobi general constraint object. General constraints are always associated with a particular model. You create a general constraint object by adding a general constraint to a model (using one of the GRBModel.AddGenConstr* methods), rather than by using a GRBGenConstr constructor.

General constraint objects have a number of attributes, which can be queried with the GRBGenConstr.Get method. The full list can be found in the Attributes section of this document.

double Get(GRB.DoubleAttr attr)#

Query the value of a double-valued general constraint attribute.

Parameters:

attr – The attribute being queried.

Returns:

The current value of the requested attribute.

int Get(GRB.IntAttr attr)#

Query the value of an int-valued general constraint attribute.

Parameters:

attr – The attribute being queried.

Returns:

The current value of the requested attribute.

string Get(GRB.StringAttr attr)#

Query the value of a string-valued general constraint attribute.

Parameters:

attr – The attribute being queried.

Returns:

The current value of the requested attribute.

void Set(GRB.DoubleAttr attr, string newvalue)#

Set the value of a double-valued general constraint attribute.

Parameters:

  • attr – The attribute being modified.

  • newvalue – The desired new value of the attribute.

void Set(GRB.IntAttr attr, string newvalue)#

Set the value of an int-valued general constraint attribute.

Parameters:

  • attr – The attribute being modified.

  • newvalue – The desired new value of the attribute.

void Set(GRB.StringAttr attr, string newvalue)#

Set the value of a string-valued general constraint attribute.

Parameters:

  • attr – The attribute being modified.

  • newvalue – The desired new value of the attribute.
