    Classes in bdi4jade.belief that implement MetadataElement
    Modifier and Type | Class and Description
    --- | ---
    `class` | `AbstractBelief<K,V>` This is an abstract class that implements the `Belief` interface.
    `class` | `AbstractBeliefSet<K,V>` This is an abstract class that implements the `BeliefSet` interface, and extends the `AbstractBeliefSet` class, parameterizing it with a parameterized `Set`.
    `class` | `DerivedBelief<K,V>` This class represents a belief whose value is derived from other beliefs of a belief base.
    `class` | `DerivedPredicate<K>` This class represents a logic predicate that is derived from other agent belief.
    `class` | `PersistentBelief<K,V>` This class extends the `AbstractBelief` and represents a persistent belief, which is persisted in a permanent memory.
    `class` | `TransientBelief<K,V>` This class extends the `AbstractBelief` class and represents a transient belief, which is not persisted in a permanent memory.
    `class` | `TransientBeliefSet<K,V>` This class extends the `AbstractBeliefSet` class and implements `BeliefSet` interface, representing a transient belief set, which is not persisted in a permanent memory.
    `class` | `TransientPredicate<K>` This class extends the `TransientBelief` class and represents a transient propositional belief, which is not persisted in a permanent memory.
