Constructor Detail

IloNumExpr

public IloNumExpr()
This constructor creates an empty handle. You must initialize it before you use it.

IloNumExpr

public IloNumExpr(IloNumExpr::ImplClass * impl)
This constructor creates a handle object from a pointer to an implementation object.

IloNumExpr

public IloNumExpr(const IloNumExprArg expr)

This constructor creates a numeric expression using the undocumented class IloNumExprArg.

IloNumExpr

public IloNumExpr(const IloEnv env, IloNum )

This constructor creates a numeric expression in the environment indicated by env. It may be used to build other expressions from variables belonging to env.

IloNumExpr

public IloNumExpr(const IloNumLinExprTerm term)

This constructor creates a numeric expression using the undocumented class IloNumLinExprTerm.

IloNumExpr

public IloNumExpr(const IloIntLinExprTerm term)

This constructor creates a numeric expression using the undocumented class IloIntLinExprTerm.

IloNumExpr

public IloNumExpr(const IloExpr & expr)

This is the copy constructor for this class.

Method Detail

getImpl

public IloNumExpr::ImplClass * getImpl()
This member function returns a pointer to the implementation object of the invoking handle.

operator *=

public IloNumExpr & operator *=(IloNum val)

This operator is recommended for building a Concert Technology expression in a loop. It is more efficient than x = x * ...

operator+=

public IloNumExpr & operator+=(const IloNumExprArg expr)

This operator is recommended for building a Concert Technology expression in a loop. It is more efficient than x = x + ...

operator+=

public IloNumExpr & operator+=(IloNum val)

This operator is recommended for building a Concert Technology expression in a loop. It is more efficient than x = x + ...

operator-=

public IloNumExpr & operator-=(const IloNumExprArg expr)

This operator is recommended for building a Concert Technology expression in a loop. It is more efficient than x = x - ...

operator-=

public IloNumExpr & operator-=(IloNum val)

This operator is recommended for building a Concert Technology expression in a loop. It is more efficient than x = x - ...

operator/=

public IloNumExpr & operator/=(IloNum val)

This operator is recommended for building a Concert Technology expression in a loop. It is more efficient than x = x / ...
