Class RequestApp

java.lang.Object
  com.sun.sgs.example.request.server.RequestApp

All Implemented Interfaces:

com.sun.sgs.app.AppListener, Serializable

public class RequestApp
extends Object
implements com.sun.sgs.app.AppListener, Serializable

Defines an AppListener that responds to channel and name binding requests from the client.

Clients can request to join, leave, or send messages on channels, which are identified by name. Clients can also set or get string values associated with name bindings. Getting a name binding results in the value being sent back to the client in a separate message. Multiple arguments in a request should be separated by spaces. Clients can make multiple requests that will be processed within a single task by including the requests in a single message, separated by newlines.

Here are the supported requests:

• JoinChannel channelName
• LeaveChannel channelName
• SendChannel channelName message
• GetItem itemName
• SetItem itemName value

This class supports the following properties:

• com.sun.sgs.example.request.server.report - The number of seconds between logging performance data, defaults to 20
