GRBModel::get()
Query the value(s) of an attribute. Use this method for scalar model attributes, or for arrays of constraint or variable attributes.
| char* | get ( | GRB_CharAttr | attr, |
| const GRBVar* | vars, | ||
| int | count ) |
-
Query a char-valued variable attribute for an array of variables.
Arguments:
attr: The attribute being queried.
vars: An array of variables whose attribute values are being queried.
count: The number of variable attributes to retrieve.
Return value:
The current values of the requested attribute for each input variable. Note that the result is heap-allocated, and must be returned to the heap by the user.
| char* | get ( | GRB_CharAttr | attr, |
| const GRBConstr* | constrs, | ||
| int | count ) |
-
Query a char-valued constraint attribute for an array of
constraints.
Arguments:
attr: The attribute being queried.
constrs: An array of constraints whose attribute values are being queried.
count: The number of constraint attributes to retrieve.
Return value:
The current values of the requested attribute for each input constraint. Note that the result is heap-allocated, and must be returned to the heap by the user.
| char* | get ( | GRB_CharAttr | attr, |
| const GRBQConstr* | qconstrs, | ||
| int | count ) |
-
Query a char-valued quadratic constraint attribute for an array of
quadratic constraints.
Arguments:
attr: The attribute being queried.
constrs: An array of quadratic constraints whose attribute values are being queried.
count: The number of quadratic constraint attributes to retrieve.
Return value:
The current values of the requested attribute for each input quadratic constraint. Note that the result is heap-allocated, and must be returned to the heap by the user.
| double | get ( | GRB_DoubleAttr | attr ) |
Query the value of a double-valued model attribute.
Arguments:
attr: The attribute being queried.
Return value:
The current value of the requested attribute.
| double* | get ( | GRB_DoubleAttr | attr, |
| const GRBVar* | vars, | ||
| int | count ) |
-
Query a double-valued variable attribute for an array of
variables.
Arguments:
attr: The attribute being queried.
vars: An array of variables whose attribute values are being queried.
count: The number of variable attributes to retrieve.
Return value:
The current values of the requested attribute for each input variable. Note that the result is heap-allocated, and must be returned to the heap by the user.
