Interface RuleBase

All Superinterfaces:

Serializable

All Known Subinterfaces:

InternalRuleBase

All Known Implementing Classes:

AbstractRuleBase, ReteooRuleBase

---

public interface RuleBase
extends Serializable

Active collection of Rules.

From a RuleBase many WorkingMemory rule sessions may be instantiated. Additionally, it may be inspected to determine which Package s it contains.

Method Detail

newStatelessSession

StatelessSession newStatelessSession()

---

newStatefulSession

StatefulSession newStatefulSession()

Create a new WorkingMemory session for this RuleBase. By default the RuleBase retains a weak reference to returned WorkingMemory.

The created WorkingMemory uses the default conflict resolution strategy.

Returns:

A newly initialized WorkingMemory.

See Also:

WorkingMemory, DefaultConflictResolver

---

newStatefulSession

StatefulSession newStatefulSession(boolean keepReference)

Create a new WorkingMemory session for this RuleBase. Optionally the RuleBase retains a weak reference to returned WorkingMemory.

The created WorkingMemory uses the default conflict resolution strategy.

Returns:

A newly initialized WorkingMemory.

See Also:

WorkingMemory, DefaultConflictResolver

---

newStatefulSession

StatefulSession newStatefulSession(InputStream stream)
                                   throws IOException,
                                          ClassNotFoundException

RuleBases handle the returning of a Serialized WorkingMemory pass as an InputStream. If the reference is a byte[] then wrap with new ByteArrayInputStream. By default the RuleBase retains a weak reference to returned WorkingMemory.

The created WorkingMemory uses the default conflict resolution strategy.

Returns:

A serialised initialized WorkingMemory.

Throws:

IOException

ClassNotFoundException

See Also:

WorkingMemory, DefaultConflictResolver

---

newStatefulSession

StatefulSession newStatefulSession(InputStream stream,
                                   boolean keepReference)
                                   throws IOException,
                                          ClassNotFoundException

RuleBases handle the returning of a Serialized WorkingMemory pass as an InputStream. If the reference is a byte[] then wrap with new ByteArrayInputStream. Optionally the RuleBase retains a weak reference to returned WorkingMemory.

The created WorkingMemory uses the default conflict resolution strategy.

Returns:

A serialised initialized WorkingMemory.

Throws:

IOException

ClassNotFoundException
