As tuple arrives on the input port a message is triggered and transmitted to all currently connected clients. Clients can connect and disconnect at anytime.

Optional: binaryMessageAttributeName, certificateAlias, context, contextResourceBase, enableConnectionControlMessages, host, keyPassword, keyStore, keyStorePassword, port, sslAppConfigName, textMessage, trustStore, trustStorePassword
Input port: Tuples received on this port generate a message to be transmitted over to all connected websocket clients. The content of the transmitted message is determined with parameter textMessage or binaryMessageAttributeName. If both parameters are absend, the input tuple is converted into a JSON formatted messages and transmitted to all currently connected clients
Optional: binaryMessageAttributeName, certificateAlias, context, contextResourceBase, enableConnectionControlMessages, host, keyPassword, keyStore, keyStorePassword, port, sslAppConfigName, textMessage, trustStore, trustStorePassword
The input attribute name which is used as binary message. The type of this attribute must be blob. If this parameter is set, parameter textMessage is not allowed.
Alias of the certificate to use in the key store. When this parameter is set all connections use HTTPS and parameters keyStore and keyPassword are required.
Define a URL context path that maps to the resources defined by contextResourceBase. This allows a composite that invokes this operator in a toolkit to provide resources regardless of the value of the application's data directory. For example setting it to maps would result in the URL /maps/index.html mapping to the file index.html in the directory defined by contextResourceBase. Requires the parameter contextResourceBase to be set. If when the operator is initialized the context already exists then no action is taken. This allows multiple independent composites in the same toolkit to have common context and contextResourceBase settings, typically to point to a single set of HTML and Javascript resources for the toolkit.
If the operator provides URLs for its input or output ports then they are placed in the this context when this parameter is set. This then provides fixed locations for the URLs regardless of the depth of the operator invocation in the main composite.
Only a single context per invocation is supported.
Directory location of resources that will be available through the the URL context defined by the parameter context. Typically used to allow a toolkit to provide a set of resources in a fixed location. The set of resources is recommended to be stored in the application_dir/opt directory, which is automatically included in the bundle by default. Path of this directory can be absolute or relative, if relative path is specified then it is relative to the application directory. A set of default resources is included in the toolkit directory under ToolkitDir/opt/resources and will be loaded by the operator. This default resources can be viewed at http://hostname:8080/streamsx.inet.resources. A path within the application is obtained using the SPL function getThisToolkitDir(). Thus a composite in the file maps.spl in the namespace directory com.acme.streams.apps.map might have the following setting to map http://127.0.0.1:8080/maps to opt/resources/mapinfo in the application.
param context: “maps” contextResourceBase: getThisToolkitDir() + “/opt/resources/mapinfo”
If this parameter is applied parameter contextResourceBase is required too.
If this parameteter is true, the operator sends out a connection control message to all connected websocket clients, when a client gets connected or disconnected. Default is true.
You can configure a host either as a host name or IP address to identify a specific network interface on which to listen. If not set, or set to the value of 0.0.0.0, the integrated jetty server listens on all local interfaces.
Password to the private key.
URL to the key store containing the certificate. If a relative file path then it is taken as relative to the application directory.
Password to the key store.
Port number for the embedded Jetty HTTP server, default: "8080". If the port is set to 0, the jetty server uses a free tcp port, and the metric serverPort delivers the actual value.

The input attribute which is used as text message. The attribute must be of type rstring or ustring. If this parameter is set, parameter binaryMessageAttributeName is not allowed.
URL to the trust store containing client certificates. If a relative file path then it is taken as relative to the application directory. When this parameter is set, client authentication is required.
Password to the trust store.
Jetty SSL/TLS status: 0=HTTP, 1=HTTPS.
Number of clients currently connected to the operators WebSocket context.
Number of messages sent using WebSocket (cumulative sum for all connected clients)
Jetty (HTTP/HTTPS) server port if the operator hosts the server, 0 otherwise
