Interface SyncNodeServer

public interface SyncNodeServer
API of the Node associated to a server endpoint using a synchronous network protocol.

You must bind this kind of node on the server's side if you plan to use a Client-Server communication protocol, such as standard HTTP for example.

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

  • RemotePluginServer
  • LocalServiceServer
To create it, you must only bind a sync node during the initialization process.
Then, you can access it on the server's side from the using the getSyncNode() method of the associated above distributed component.
