Examples of com.sun.sgs.protocol.SessionProtocol

com.sun.sgs.protocol.SessionProtocol
A protocol for sending session messages and channel messages to a client.
The implementation of the protocol is only responsible for the formating and sending of messages to the client. Unless otherwise noted, the implementation is not required to perform validity checks on method arguments. For calls that result in messages sent to a client, is up to the caller to make sure arguments contain valid information. It is up to the client to decide what it wants to do if it receives messages that seem nonsensical.
If a protocol specification requires that a login acknowledgment be delivered to a client before any other protocol messages, the protocol must implement this requirement. It is possible that a caller may request that other messages be sent before a login acknowledgment, and if the protocol requires, these messages should be enqueued until the login acknowledgment has been sent to the client.
