Interface Summary Interface Description ClientEndpointConfig The ClientEndpointConfig is a special kind of endpoint configuration object that contains web socket configuration information specific only to client endpoints. CloseReason.CloseCode A marker interface for the close codes. Decoder The Decoder interface holds member interfaces that define how a developer can provide the web socket container a way web socket messages into developer defined custom objects. Decoder.Binary This interface defines how a custom object (of type T) is decoded from a web socket message in the form of a byte buffer. Decoder.BinaryStream This interface defines how a custom object is decoded from a web socket message in the form of a binary stream. Decoder.Text This interface defines how a custom object is decoded from a web socket message in the form of a string. Decoder.TextStream This interface defines how a custom object of type T is decoded from a web socket message in the form of a character stream. Encoder The Encoder interface defines how developers can provide a way to convert their custom objects into web socket messages. Encoder.Binary This interface defines how to provide a way to convert a custom object into a binary message. Encoder.BinaryStream This interface may be implemented by encoding algorithms that want to write the encoded object to a binary stream. Encoder.Text This interface defines how to provide a way to convert a custom object into a text message. Encoder.TextStream This interface may be implemented by encoding algorithms that want to write the encoded object to a character stream. EndpointConfig The endpoint configuration contains all the information needed during the handshake process for this end point. Extension A simple representation of a websocket extension as a name and map of extension parameters. Extension.Parameter This member interface defines a single websocket extension parameter. HandshakeResponse The handshake response represents the web socket-defined Http response that is the response to the opening handshake request. MessageHandler Developers implement MessageHandlers in order to receive incoming messages during a web socket conversation. MessageHandler.Partial This kind of handler is notified by the implementation as it becomes ready to deliver parts of a whole message. MessageHandler.Whole This kind of handler is notified by the container on arrival of a complete message. PongMessage The PongMessage interface represents a web socket pong. RemoteEndpoint The RemoteEndpoint object is supplied by the container and represents the 'other end' or peer of the Web Socket conversation. RemoteEndpoint.Async This representation of the peer of a web socket conversation has the ability to send messages asynchronously. RemoteEndpoint.Basic This representation of the peer of a web socket conversation has the ability to send messages synchronously. SendHandler A simple callback object for asynchronous sending of web socket messages. Session A Web Socket session represents a conversation between two web socket endpoints. WebSocketContainer A WebSocketContainer is an implementation provided object that provides applications a view on the container running it. Class Summary Class Description ClientEndpointConfig.Builder The ClientEndpointConfig.Builder is a class used for creating ClientEndpointConfig objects for the purposes of deploying a client endpoint. ClientEndpointConfig.Configurator The Configurator class may be extended by developers who want to provide custom configuration algorithms, such as intercepting the opening handshake, or providing arbitrary methods and algorithms that can be accessed from each endpoint instance configured with this configurator. CloseReason A class encapsulating the reason why a web socket has been closed, or why it is being asked to close. ContainerProvider Provider class that allows the developer to get a reference to the implementation of the WebSocketContainer. Endpoint The Web Socket Endpoint represents an object that can handle websocket conversations. SendResult The result of asynchronously sending a web socket message. Enum Summary Enum Description CloseReason.CloseCodes An Enumeration of status codes for a web socket close that are defined in the specification. Exception Summary Exception Description DecodeException A general exception that occurs when trying to decode a custom object from a text or binary message. DeploymentException Checked exception indicating some kind of failure either to publish an endpoint on its server, or a failure to connect a client to its server. EncodeException A general exception that occurs when trying to encode a custom object to a string or binary message. SessionException A SessionException represents a general exception type reporting problems occurring on a websocket session. Annotation Types Summary Annotation Type Description ClientEndpoint The ClientEndpoint annotation a class level annotation is used to denote that a POJO is a web socket client and can be deployed as such. OnClose This method level annotation can be used to decorate a Java method that wishes to be called when a web socket session is closing. OnError This method level annotation can be used to decorate a Java method that wishes to be called in order to handle errors. OnMessage This method level annotation can be used to make a Java method receive incoming web socket messages. OnOpen This method level annotation can be used to decorate a Java method that wishes to be called when a new web socket session is open.
