This interface should be implemented by classes that wish to
act as connection servers and to accept requests from
ConnectionClient
objects.
The server can call request()
to allow a client
to establish a connection to the server and to obtain the client's
initial request. This should block until a client establishes a
connection.
Once a request has been received, the server should reply to the client.
If the server wants to close the connection then the server should call
replyAndClose(Object)
or alternatively
reply(Object, boolean)
with the boolean
set to
true
. If the server wants to keep the connection open, then it
should call reply(Object)
or alternatively
reply(Object, boolean)
with the boolean
set to
false
. The reply(Object, boolean)
method is
provided for convenience in closing connections programatically.

Method Details
-
request
Receives a request from a client. This will block until the client calls its
request(Object)
method. Implementations may make this ALTable.After this method has returned, the server should call one of the reply methods. Performing any external process synchronization between these method calls could be potentially hazardous and could lead to deadlock.
- Returns:
- the
Object
sent by the client. - Throws:
IllegalStateException
-
reply
Sends some data back to the client after a request has been received but keeps the connection open. After calling this method, the server should call
recieve()
to receive a further request.A call to this method is equivalent to a call to
reply(Object, boolean)
with the boolean set tofalse
.- Parameters:
data
- the data to send to the client.- Throws:
IllegalStateException
-
reply
Sends some data back to the client after a request has been received. The
boolean
close parameter indicates whether the connection should be closed after this reply has been sent.This method should not block.
- Parameters:
data
- the data to send back to client.close
-boolean
that should betrue
iff the connection should be dropped after the reply has been sent.
-
replyAndClose
Sends some data back to the client and closes the connection.
A call to this method is equivalent to a call to
reply(Object, boolean)
with the boolean set totrue
.- Parameters:
data
- the data to send back to client.- Throws:
IllegalStateException
