Package org.jcsp.net
Class LinkServer
java.lang.Object
org.jcsp.net.LinkServer
An abstract class that must be implemented by communication
protocol implementations.
LinkServer
objects are
processes which listen on a certain address for connection
requests. When a request is received, a Link
should be spawned in
server mode.- Author:

LinkServer
Constructor. A LinkServer must have an associated protocolID.- Parameters:
protocolID
- TheProtocolID
for the protocol that the concrete implementation ofLinkServer
supports.linkServerAddressID
- theNodeAddressID
for thisLinkServer
to listen on.

Method Details
-
create
Create a server on a specifiedNodeAddressID, and start it. The server is spawned off in parallel, so this call returns immediately. This needs to be implemented by the concrete implementation of this class. This is not enforced by the compiler due to this being a static method. This NEEDS to be overridden.- Parameters:
addressID
- The NodeAddressID to accept from- Returns:
- the instance of
LinkServer
.
-
stop
protected boolean stop()Stops the LinkServer. This NEEDS to be overridden.- Returns:
true
iff theLinkServer
has stopped.
-
getProtocolID
Gets the protocol that this LinkServer supports.- Returns:
- the ProtocolID representing this LinkServers protocol.
-
getLinkServerAddressID
Protected accessor for obtaining theNodeAddressID
on which this server is listening.- Returns:
- the
NodeAddressID
on which this server is listening.
