MessageBus class¶

Attributes: [DebuggerDisplay("Messages = {_messageBus.Count}, SchedulerMappings = {_schedulerMappings.Count}")]

Defined in

Namespace: ReactiveUI Assembly: ReactiveUI.dll Full name: ReactiveUI.MessageBus Modifiers: public

Summary¶

MessageBus represents an object that can act as a "Message Bus", a simple way for ViewModels and other objects to communicate with each other in a loosely coupled way.

Specifying which messages go where is done via a combination of the Type of the message as well as an additional "Contract" parameter; this is a unique string used to distinguish between messages of the same Type, and is arbitrarily set by the client.

Methods¶

Name	Summary
RegisterScheduler	Registers a scheduler for the type, which may be specified at runtime, and the contract.
Listen	Listen provides an Observable that will fire whenever a Message is provided for this object via RegisterMessageSource or SendMessage.
ListenIncludeLatest	Listen provides an Observable that will fire whenever a Message is provided for this object via RegisterMessageSource or SendMessage.
IsRegistered	Determines if a particular message Type is registered.
RegisterMessageSource	Registers an Observable representing the stream of messages to send. Another part of the code can then call Listen to retrieve this Observable.
SendMessage	Sends a single message using the specified Type and contract. Consider using RegisterMessageSource instead if you will be sending messages in response to other changes such...
