Constants ¶

const NoopHandler = noopHandler(0)

NoopHandler is a Handler that does nothing and always returns nil

Types ¶

type Handler ¶

type Handler interface {
	HandleEvent(context.Context, *scheduler.Event) error
}

Handler is invoked upon the occurrence of some scheduler event that is generated by some other component in the Mesos ecosystem (e.g. master, agent, executor, etc.)

type HandlerFunc ¶

type HandlerFunc func(context.Context, *scheduler.Event) error

HandlerFunc is a functional adaptation of the Handler interface

func (HandlerFunc) HandleEvent ¶

func (f HandlerFunc) HandleEvent(ctx context.Context, e *scheduler.Event) error

HandleEvent implements Handler for HandlerFunc

type HandlerFuncs ¶

type HandlerFuncs map[scheduler.Event_Type]HandlerFunc

HandlerFuncs executes an event HandlerFunc according to the event's type

func (HandlerFuncs) HandleEvent ¶

func (hs HandlerFuncs) HandleEvent(ctx context.Context, e *scheduler.Event) (err error)

HandleEvent implements Handler for HandlerFuncs

func (HandlerFuncs) Otherwise ¶

func (hs HandlerFuncs) Otherwise(f HandlerFunc) HandlerFunc

Otherwise returns a HandlerFunc that attempts to process an event with the HandlerFuncs map; unmatched event types are processed by the given HandlerFunc. A nil HandlerFunc parameter is effecitvely a noop.

type Handlers ¶

type Handlers map[scheduler.Event_Type]Handler

Handlers executes an event Handler according to the event's type

func (Handlers) HandleEvent ¶

func (hs Handlers) HandleEvent(ctx context.Context, e *scheduler.Event) (err error)

HandleEvent implements Handler for Handlers

func (Handlers) Otherwise ¶

func (hs Handlers) Otherwise(f HandlerFunc) HandlerFunc

Otherwise returns a HandlerFunc that attempts to process an event with the Handlers map; unmatched event types are processed by the given HandlerFunc. A nil HandlerFunc parameter is effecitvely a noop.
