Interface RuleBase

All Superinterfaces:

java.io.Serializable

All Known Subinterfaces:

InternalRuleBase

All Known Implementing Classes:

AbstractRuleBase

public interface RuleBase

extends java.io.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

newWorkingMemory

public WorkingMemory newWorkingMemory()

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

newWorkingMemory

public WorkingMemory newWorkingMemory(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

newWorkingMemory

public WorkingMemory newWorkingMemory(java.io.InputStream stream)
                               throws java.io.IOException,
                                      java.lang.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.

Throws:

java.io.IOException

java.lang.ClassNotFoundException

Returns:

A serialised initialized WorkingMemory.

WorkingMemory, DefaultConflictResolver

newWorkingMemory

public WorkingMemory newWorkingMemory(java.io.InputStream stream,
                                      boolean keepReference)
                               throws java.io.IOException,
                                      java.lang.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.

Throws:

java.io.IOException

java.lang.ClassNotFoundException

Returns:

A serialised initialized WorkingMemory.
