MultiCallback.h File Reference

Detailed Description

A callback which can be executed multiple times. When a pre-defined limit is reached, then the underlying callback is executed.

Example

// Calls DoSomething() for each Port and runs the on_complete callback once
// each port's callback has run.
void DoSomethingForAllPorts(const vector<OutputPort> &ports,
                            SomethingCalback *on_complete) {
  // This will call on_complete once it itself has been Run ports.size()
  // times.
  BaseCallback0<void> *multi_callback = NewMultiCallback( ports.size(),
      NewSingleCallback(this, &SomethingComplete,
      on_complete));

  vector<OutputPort*>::iterator iter;
  for (iter = output_ports.begin(); iter != output_ports.end(); ++iter) {
    (*iter)->DoSomething(multi_callback);
  }
}
