        public int getMaxBinaryMessageBufferSize()
        Get the maximum length of incoming binary messages that this Session can buffer. If the implementation receives a binary message that it cannot buffer because it is too large, it must close the session with a close code of CloseReason.CloseCodes.TOO_BIG.
        Specified by:
        getMaxBinaryMessageBufferSize in interface Session
        Returns:
        the maximum binary message size that can be buffered.

        Returns:
        the remote endpoint representation.

      • getBasicRemote

        public RemoteEndpoint.Basic getBasicRemote()
        Get a reference a RemoteEndpoint.Basic object representing the peer of this conversation that is able to send messages synchronously to the peer.

        Specified by:
        getId in interface Session
        Returns:
        the unique identifier for this session instance.

      • close

        public void close()
           throws java.io.IOException
        Close the current conversation with a normal status code and no reason phrase.
        Specified by:
        close in interface java.lang.AutoCloseable
        Specified by:
        close in interface java.io.Closeable
        Specified by:
        close in interface Session
        Throws:
        java.io.IOException - if there was a connection error closing the connection.

      • close

        public void close​(CloseReason closeReason)
           throws java.io.IOException
        Close the current conversation, giving a reason for the closure. The close call causes the implementation to attempt notify the client of the close as soon as it can. This may cause the sending of unsent messages immediately prior to the close notification. After the close notification has been sent the implementation notifies the endpoint's onClose method. Note the websocket specification defines the acceptable uses of status codes and reason phrases. If the application cannot determine a suitable close code to use for the closeReason, it is recommended to use CloseReason.CloseCodes.NO_STATUS_CODE.
        Specified by:
        close in interface Session
        Parameters:
        closeReason - the reason for the closure.
        Throws:
        java.io.IOException - if there was a connection error closing the connection.

      • getRequestParameterMap

        public java.util.Map<java.lang.String,​java.util.List<java.lang.String>> getRequestParameterMap()
        Get the request parameters associated with the request this session was opened under.
        Specified by:
        getRequestParameterMap in interface Session
        Returns:
        the unmodifiable map of the request parameters.

      • getQueryString

        public java.lang.String getQueryString()
        Get the query string associated with the request this session was opened under.
        Specified by:
        getQueryString in interface Session
        Returns:
        the query string.

      • getPathParameters

        public java.util.Map<java.lang.String,​java.lang.String> getPathParameters()

        getPathParameters in interface Session
        Returns:
        the unmodifiable map of path parameters. The key of the map is the parameter name, the values in the map are the parameter values.

      • getUserProperties

        public java.util.Map<java.lang.String,​java.lang.Object> getUserProperties()
        This method is not supported on RemoteSession. Each invocation will throw an UnsupportedOperationException.
        Specified by:
        getUserProperties in interface Session
        Returns:
        nothing.
        See Also:
        getDistributedProperties()

      • getDistributedProperties

        public java.util.Map<java.lang.String,​java.lang.Object> getDistributedProperties()
        Description copied from interface: DistributedSession
        Get distributed properties.

        Values put into this map must be Serializable or serializable by other, implementation-dependent alternative.

        Content of this map is synchronized among all cluster nodes, so putting an entry on any of the nodes will be visible on all other nodes which have reference to current session (in form of TyrusSession or RemoteSession).

        Please note that when not running in the distributed environment, this map behaves similarly to Session.getUserProperties(), so no serialization or deserialization is performed when values are read from or stored to the returned map.

        Specified by:
        getDistributedProperties in interface DistributedSession
        Returns:
        map of distributed properties.
