Test
The test can be carried out by running a negotiation. The following code is
the driver for the test; it must be completed by writing the following methods:
the
defineSpecification()
method creates the specification, e.g. reading it
from a file;
■
the
createClientPref()
method creates the preferences for the client;
■
the
createProviderPref()
method creates the preferences for the service
provider.

// define the specification of the problem that consists
// of attributes and the enumeration of their possible
// values

#
defineSpecification();
System.out.println(spec);
// define the preference map of the client
PreferenceMap clientPref
#
createClientPref(spec);
// creates the client negotiator
Negotiator client
#
new
BasicNegotiator(clientPref);
// define the preference map of the server
PreferenceMap providerPref
#
createProvider Pref(spec);
// creates the server negotiator
Negotiator provider
#
new

// carry out the negotiation
Mediator mediator
#
new
Mediator(10);
// print the result if successful
