Examples of InvocationConstraints

net.jini.core.constraint.InvocationConstraints
An immutable aggregation of constraints into a set of requirements and a set of preferences. A requirement is a mandatory constraint that must be satisfied for the invocation. A preference is a desired constraint, to be satisfied if possible, but it will not be satisfied if it conflicts with a requirement. If two preferences conflict, it is arbitrary as to which one will be satisfied. If a constraint is not understood, due to lack of knowledge of the type of the constraint or the contents of the constraint, then the constraint cannot be satisfied.
Note that it is possible for an instance of this class to contain both requirements that conflict with each other, and preferences that conflict with each other and with requirements. @author Sun Microsystems, Inc. @since 2.0
