Method Detail

invoke

public virtual void invoke(Callback::Context const & context)

This method invokes the CPLEX generic callback. If an object is registered with CPLEX by means of the method IloCplex::use(Callback::Function, long), then CPLEX will invoke this function of the registered object in all contexts requested by the argument contextMask passed to IloCplex::use(Callback::Function, long).

Note that in this function you must not invoke any functions of the IloCplex that is performing the current solve. All functions that can be invoked from a callback are members of context.

which context the callback is invoked, which progress information can be queried, and which actions can be performed. This instance is valid only during execution of the callback function. Do not keep a reference to it.

Parameters:

context
An instance of IloCplex::Callback::Context that defines in which context the callback is invoked, which progress information can be queried, and which actions can be performed. This instance is valid only during execution of the callback function. Do not keep a reference to it.
