Examples with EndpointObserver org.eclipse.californium.core.network.EndpointObserver used on opensource projects

Example 1 with EndpointObserver

use of org.eclipse.californium.core.network.EndpointObserver in project californium by eclipse.

the class CoapServer method addEndpoint.

/**
 * Adds an Endpoint to the server.
 *
 * WARNING: It automatically configures the default executor of the server.
 * Endpoints that should use their own executor (e.g., to prioritize or
 * balance request handling) either set it afterwards before starting the
 * server or override the setExecutor() method of the special Endpoint.
 *
 * @param endpoint the endpoint to add
 */
