Detailed Description

This is so user can trap events and do useful stuff.

This is used in Clp/Test/unitTest.cpp

ClpSimplex model_ is available as well as anything else you care to pass in

Constructor & Destructor Documentation

◆ MyEventHandler() [1/3]

MyEventHandler::MyEventHandler ( )

Default constructor.

◆ MyEventHandler() [2/3]

MyEventHandler::MyEventHandler ( ClpSimplex model)

Constructor with pointer to model (redundant as setEventHandler does)

◆ ~MyEventHandler()

virtual MyEventHandler::~MyEventHandler ( )
virtual

Destructor.

◆ MyEventHandler() [3/3]

MyEventHandler::MyEventHandler ( const MyEventHandler rhs)

The copy constructor.

Member Function Documentation

◆ event()

virtual int MyEventHandler::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. For ClpSolve 2 -> too big return status of -2 and -> too small 3

Reimplemented from ClpEventHandler.

◆ operator=()

MyEventHandler & MyEventHandler::operator= ( const MyEventHandler rhs)

Assignment.

◆ clone()

virtual ClpEventHandler * MyEventHandler::clone ( ) const
virtual

Clone.

Reimplemented from ClpEventHandler.
