Constructor Detail

AlphaNode

public AlphaNode(int id,
                 AlphaNodeFieldConstraint constraint,
                 ObjectSource objectSource)

Construct an AlphaNode with a unique id using the provided FieldConstraint and the given ObjectSource. Nodes created in this way will have a local memory by default.

Parameters:

id -

constraint -

objectSource -

AlphaNode

public AlphaNode(int id,
                 AlphaNodeFieldConstraint constraint,
                 ObjectSource objectSource,
                 boolean hasMemory,
                 int alphaNodeHashingThreshold)

Construct an AlphaNode with a unique id using the provided FieldConstraint and the given ObjectSource. Set the boolean flag to true if the node is supposed to have local memory, or false otherwise. Memory is optional for AlphaNodes and is only of benefic when adding additional Rules at runtime.

Parameters:

id - Node's ID

constraint - Node's constraints

objectSource - Node's object source

hasMemory - true if node shall be configured with local memory. False otherwise.

getConstraint

public AlphaNodeFieldConstraint getConstraint()

Retruns the FieldConstraint

Returns:

FieldConstraint

attach

public void attach()

Description copied from class: BaseNode

Attaches the node into the network. Usually to the parent ObjectSource or TupleSource

Specified by:

attach in class BaseNode

attach

public void attach(InternalWorkingMemory[] workingMemories)

Specified by:

attach in class BaseNode

assertObject

public void assertObject(InternalFactHandle handle,
                         PropagationContext context,
                         InternalWorkingMemory workingMemory)
                  throws FactException

Description copied from interface: ObjectSink

Assert a new FactHandleImpl.

Specified by:

assertObject in interface ObjectSink

Parameters:

handle - The asserted FactHandle/code>.

context - The PropagationContext of the WorkingMemory action.

workingMemory - the WorkingMemory session.

Throws:
