Interface Session

All Superinterfaces:
AutoCloseable, Closeable
public interface Session extends Closeable

  • Method Details

    • getContainer

      WebSocketContainer getContainer()
      Get the container that created this session.
      Returns:
      the container that created this session.

    • addMessageHandler

      void addMessageHandler(MessageHandler handler) throws IllegalStateException
      Registers a MessageHandler for incoming messages. Only one MessageHandler may be registered for each message type (text, binary, pong). The message type will be derived at runtime from the provided MessageHandler instance. It is not always possible to do this so it is better to use addMessageHandler(Class, javax.websocket.MessageHandler.Partial) or addMessageHandler(Class, javax.websocket.MessageHandler.Whole).
      Parameters:
      handler - The message handler for a incoming message
      Throws:
      IllegalStateException - If a message handler has already been registered for the associated message type

    • getMaxIdleTimeout

      long getMaxIdleTimeout()
      Get the idle timeout for this session.
