ILOG CPLEX C++ API 9.0 Reference Manual

IloCplex
This method deletes all lazy constraints added to the invoking IloCplex object with
the methods addLazyConstraint and addLazyConstraints.
This method is equivalent to clearCuts.
public void clearModel()
This method can be used to unextract the model that is currently extracted to the
invoking IloCplex object.
public void clearUserCuts()
Note:This is an advanced method. Advanced methods typically demand a profound
understanding of the algorithms used by ILOG CPLEX. Thus they incur a higher
risk of incorrect behavior in your application, behavior that can be difficult to
debug. Therefore, ILOG encourages you to consider carefully whether you can
accomplish the same task by means of other methods instead.
This method deletes all user cuts that have previously been added to the invoking
IloCplex object with the methods addUserCut and addUserCuts.
public void delDirection(IloNumVar var)
This method removes any existing branching direction assignment from variable var.
public void delDirections(const IloNumVarArray var)
This method removes any existing branching direction assignments from all variables in
the array var.
public void delPriorities(const IloNumVarArray var)
This method removes any existing priority order assignments from all variables in the
array var.
public void delPriority(IloNumVar var)
This method removes any existing priority order assignment from variable var.
public void exportModel(const char * filename)
This method writes the model that has been extracted to the invoking algorithm in the
file filename. The name of the file must include an extension that ILOG CPLEX
recognizes as a file format for a model. Supported formats are .sav, .lp and .mps.
See the reference manual ILOG CPLEX File Formats for more detail and the ILOG
CPLEX User's Manual for additional information about file formats.
