Types

type BaseStation 

type BaseStation struct {
	// contains filtered or unexported fields
}

func (*BaseStation) Data 

func (bs *BaseStation) Data() interface{}

func (*BaseStation) Name 

func (bs *BaseStation) Name() string

type BroadcastStation 

type BroadcastStation struct {
	BaseStation
}

func (*BroadcastStation) IsBroadcast 

func (*BroadcastStation) IsBroadcast() bool

func (*BroadcastStation) IsRemote 

func (*BroadcastStation) IsRemote() bool

type Event 

type Event struct {
	From     Station
	To       Station
	Typecode int
	Data     interface{}
}

Event is including normal event and p2p event

type Feed 

type Feed struct {
	// contains filtered or unexported fields
}

Feed implements one-to-many subscriptions where the carrier of events is a channel. Values sent to a Feed are delivered to all subscribed channels simultaneously.

Feeds can only be used with a single type. The type is determined by the first Send or Subscribe operation. Subsequent calls to these methods panic if the type does not match.

The zero value is ready to use.

func (*Feed) Send 

func (f *Feed) Send(value interface{}) (nsent int)

Send delivers to all subscribed channels simultaneously. It returns the number of subscribers that the value was sent to.

func (*Feed) Subscribe 

func (f *Feed) Subscribe(channel interface{}) Subscription

Subscribe adds a channel to the feed. Future sends will be delivered on the channel until the subscription is canceled. All channels added must have the same element type.

The channel should have ample buffer space to avoid blocking other subscribers. Slow subscribers are not dropped.

type LocalStation 

type LocalStation struct {
	BaseStation
}

func (*LocalStation) IsBroadcast 

func (*LocalStation) IsBroadcast() bool

func (*LocalStation) IsRemote 

func (*LocalStation) IsRemote() bool

type ProtoAdaptor 

type ProtoAdaptor interface {
	SendOut(*Event) error
}

ProtoAdaptor used to send out event

type RemoteStation 

type RemoteStation struct {
	BaseStation
}

func (*RemoteStation) IsBroadcast 

func (*RemoteStation) IsBroadcast() bool

func (*RemoteStation) IsRemote 

func (*RemoteStation) IsRemote() bool

type Router 

type Router struct {
	// contains filtered or unexported fields
}

Router Router all events

func New 

func New() *Router

New returns an initialized Router instance.

func (*Router) AdaptorRegister 

func (router *Router) AdaptorRegister(adaptor ProtoAdaptor)

func (*Router) GetStationByName 

func (router *Router) GetStationByName(name string) Station

func (*Router) SendEvent 

func (router *Router) SendEvent(e *Event) (nsent int)

func (*Router) StationRegister 

func (router *Router) StationRegister(station Station)

func (*Router) StationUnregister 

func (router *Router) StationUnregister(station Station)

func (*Router) Subscribe 

func (router *Router) Subscribe(station Station, channel chan *Event, typecode int, data interface{}) Subscription

type Station 

type Station interface {
	Name() string
	IsRemote() bool
	IsBroadcast() bool
	Data() interface{}
}

func GetStationByName 

func GetStationByName(name string) Station

GetStationByName retrun Station by Station's name

func NewBroadcastStation 

func NewBroadcastStation(name string, data interface{}) Station

func NewLocalStation 

func NewLocalStation(name string, data interface{}) Station

func NewRemoteStation 

func NewRemoteStation(name string, data interface{}) Station

func WorstStation added in v0.0.15 

func WorstStation() Station

type Subscription 

type Subscription interface {
	Err() <-chan error // returns the error channel
	Unsubscribe()      // cancels sending of events, closing the error channel
}

Subscription represents a stream of events. The carrier of the events is typically a channel, but isn't part of the interface.

Subscriptions can fail while established. Failures are reported through an error channel. It receives a value if there is an issue with the subscription (e.g. the network connection delivering the events has been closed). Only one value will ever be sent.

The error channel is closed when the subscription ends successfully (i.e. when the source of events is closed). It is also closed when Unsubscribe is called.

The Unsubscribe method cancels the sending of events. You must call Unsubscribe in all cases to ensure that resources related to the subscription are released. It can be called any number of times.

func Subscribe 

func Subscribe(station Station, channel chan *Event, typecode int, data interface{}) Subscription

Subscribe .
