Overview ¶
Package mediator implements the Mediator design pattern. The Aircraft interface represents the colleague entities that can request landing or takeoff operations, always via the mediator. The TrafficControl interface represents the mediator that coordinates aircraft operations. It ensures aircraft interact only indirectly, through centralized traffic organization. ControlTower is the concrete mediator, while Plane and Helicopter are concrete colleagues.

Functions ¶
Types ¶
type Aircraft ¶
type Aircraft interface {
RequestTakeOff() bool
RequestLanding() bool
CompleteOperation()
ReceiveControlMessage(string)
}
Aircraft is the common interface for all colleagues.
type ControlTower ¶
type ControlTower struct {
// contains filtered or unexported fields
}
ControlTower is the mediator that implements TrafficControl interface.
func NewControlTower ¶
func NewControlTower() *ControlTower
NewControlTower is the ControlTower constructor.
func (*ControlTower) NotifyOperationEnding ¶
func (c *ControlTower) NotifyOperationEnding(ac Aircraft)
NotifyOperationEnding implements the traffic control feedback for the operation ending attempt from the aircraft.
func (*ControlTower) RequestCraftLanding ¶
func (c *ControlTower) RequestCraftLanding(ac Aircraft) bool
RequestCraftLanding checks the runway, puts aircraft in the queue and notifies if landing can be executed.
func (*ControlTower) RequestCraftTakeoff ¶
func (c *ControlTower) RequestCraftTakeoff(ac Aircraft) bool
RequestCraftTakeoff checks the runway, puts aircraft in the queue and notifies if taking off can be executed.
type Helicopter ¶
type Helicopter struct {
ID string
// contains filtered or unexported fields
}
Helicopter is a colleague that implements Airctaft interface.
func NewHelicopter ¶
func NewHelicopter(id string, ct TrafficControl) *Helicopter
NewHelicopter is the Helicopter constructor, that receives the identifier and traffic control mediator as params.
func (*Helicopter) CompleteOperation ¶
func (h *Helicopter) CompleteOperation()
CompleteOperation tries to finish the previously requested operation.
func (*Helicopter) ReceiveControlMessage ¶
func (h *Helicopter) ReceiveControlMessage(message string)
ReceiveControlMessage logs the individual feedback from the mediator.
func (*Helicopter) RequestLanding ¶
func (h *Helicopter) RequestLanding() bool
RequestLanding notifies mediator on the landing necessity.
func (*Helicopter) RequestTakeOff ¶
func (h *Helicopter) RequestTakeOff() bool
RequestTakeOff notifies mediator on the taking off necessity.
type Plane ¶
type Plane struct {
ID string
// contains filtered or unexported fields
}
Plane is a colleague that implements Airctaft interface.
func NewPlane ¶
func NewPlane(id string, ct TrafficControl) *Plane
NewPlane is the Plane constructor, that receives the identifier and traffic control mediator as params.
func (*Plane) CompleteOperation ¶
func (p *Plane) CompleteOperation()
CompleteOperation tries to finish the previously requested operation.
func (*Plane) ReceiveControlMessage ¶
ReceiveControlMessage logs the individual feedback from the mediator.
func (*Plane) RequestLanding ¶
RequestLanding notifies mediator on the landing necessity.
func (*Plane) RequestTakeOff ¶
RequestTakeOff notifies mediator on the taking off necessity.
