Public Member Functions | |
Virtual method that the derived classe should provide. | |
The base class instance does nothing and as event() is only useful method it would not be very useful NOT providing one! | |
| virtual int | event (Event whichEvent) |
| This can do whatever it likes. | |
Constructors, destructor | |
| ClpEventHandler (ClpSimplex *model=NULL) | |
| Default constructor. | |
| virtual | ~ClpEventHandler () |
| Destructor. | |
| ClpEventHandler (const ClpEventHandler &) | |
| Default constructor. | |
| ClpEventHandler & | operator= (const ClpEventHandler &) |
| Default constructor. | |
| virtual ClpEventHandler * | clone () const |
| Clone. | |
Sets/gets | |
| void | setSimplex (ClpSimplex *model) |
| set model. | |
| ClpSimplex * | simplex () const |
| Get model. | |
Protected Attributes | |
Data members | |
The data members are protected to allow access for derived classes. | |

| Pointer to simplex. | |
This is just here to allow for event handling. By event I mean a Clp event e.g. end of values pass.
One use would be to let a user handle a system event e.g. Control-C. This could be done by deriving a class MyEventHandler which knows about such events. If one occurs MyEventHandler::event() could clear event status and return 3 (stopped).
Clp would then return to user code.
As it is called every iteration this should be fine grained enough.
User can derive and construct from CbcModel - not pretty

enums for what sort of event.
These will also be returned in ClpModel::secondaryStatus() as int

Default constructor.

Destructor.
| ClpEventHandler::ClpEventHandler | ( | const ClpEventHandler & | ) |
Default constructor.
| virtual int ClpEventHandler::event | ( | Event | whichEvent | ) | [virtual] |
This can do whatever it likes.
If return code -1 then carries on if 0 sets ClpModel::status() to 5 (stopped by event) and will return to user. At present if <-1 carries on and if >0 acts as if 0 - this may change

Default constructor.
