Class AbstractBeliefSet<T>

java.lang.Object

bdi4jade.core.MetadataElementImpl

bdi4jade.belief.AbstractBelief<java.util.Set<T>>

bdi4jade.belief.AbstractBeliefSet<T>

Type Parameters:

T - the type of the belief set values.

All Implemented Interfaces:

Belief<java.util.Set<T>>, BeliefSet<T>, MetadataElement, jade.content.Concept, jade.content.Term, java.io.Serializable

Direct Known Subclasses:

TransientBeliefSet

public abstract class AbstractBeliefSet<T>
extends AbstractBelief<java.util.Set<T>>
implements BeliefSet<T>

This is an abstract class that implements the BeliefSet interface, and extends the AbstractBeliefSet class, parameterizing it with a parameterized Set. It implements some of the interface methods, leaving some implementations to the subclasses, mainly the choice of how the belief set values are stored.
