               LocalHost localhost,
               AppManager appManager,
               java.lang.String sessionID,
               java.lang.Object remotePrimaryID,
               java.lang.Object[] args)

Creates a new instace of the Linking protocol. Note that this is instanciated by the ProtocolChooser. Application programmers should never have to instanciate protocols directly.

Parameters:

listener - The Listener for information from the remote host

sender - The Sender used to send information to the remote host

sessionType - Can be either ACTIVE (i.e. this is the first host to send data) or PASSIVE, i.e. the hsot should wait first before receiving any data.

localhost - A reference to the LocalHost, giving us access to the linktable, primaryID etc.

appManager - A reference to the AppManager, giving us access to the data on the local platform

sessionID - The unique sessionID decided for this session

remotePrimaryID - The primaryID of the remote host

args - Arguments for the linking protocol. These include information such as the application ID where the element resides /is going to be placed etc.
