Method incrementRef

dsort/manager.go:542–544

incrementRef increments reference counter. This prevents from premature cleanup. Each increment should have corresponding decrement to prevent memory leaks. NOTE: Manager should increment ref every time some data of it is used, otherwise unexpected things can happen.

// NOTE: Manager should increment ref every time some data of it is used, otherwise
// unexpected things can happen.
func (m *Manager) incrementRef(by int64) {
	m.refCount.Add(by)
}

// decrementRef decrements reference counter. If it is 0 or below and dsort has
// already finished returns true. Otherwise, false is returned.
