Interface AsyncNodeClient

public interface AsyncNodeClient
API of the Node associated to a client endpoint using an asynchronous network protocol.

You must bind this kind of node on the client's side if you plan to use a full duplex communication protocol, such as Web Sockets for example.

Then, you should provide an implementation of the AsyncEndpointClientSpi SPI in order to interact with this node.

Keyple provides its own implementations of this interface and manages their lifecycle.
This kind of node can be bind to a all client remote plugins and local services :

  • LocalServiceClient
  • RemotePluginClient
To create it, you should only bind an async node during the initialization process.
Then, you can access it everywhere on the client's side using the getAsyncNode() method of the associated above distributed component.
