Class NetworkHandlerAdaptor

java.lang.Object

org.drools.core.reteoo.compiled.NetworkHandlerAdaptor

All Implemented Interfaces:

NetworkHandler

Direct Known Subclasses:

AssertHandler, DeclarationsHandler, SetNodeReferenceHandler

public class NetworkHandlerAdaptor
extends Object
implements NetworkHandler

An abstract adapter class for receiving network node events from the org.kie.reteoo.compiled.ObjectTypeNodeParser. The methods in this class are empty. This class exists as convenience for creating handler objects.

Extend this class to create a NetworkHandler and override the methods for the nodes of interest. (If you implement the NetworkHandler interface, you have to define all of the methods in it. This abstract class defines null methods for them all, so you can only have to define methods for events you care about.)

Method Detail

startObjectTypeNode

public void startObjectTypeNode(ObjectTypeNode objectTypeNode)

Description copied from interface: NetworkHandler

Receive notification of the beginning of an org.kie.reteoo.ObjectTypeNode

The Network parser will invoke this method only once, before any other event callback.

Specified by:

startObjectTypeNode in interface NetworkHandler

Parameters:

objectTypeNode - the object type node

See Also:

#endObjectTypeNode(org.kie.reteoo.ObjectTypeNode)

startNonHashedAlphaNode

public void startNonHashedAlphaNode(AlphaNode alphaNode)

Description copied from interface: NetworkHandler

Receive notification of the a non-hashed org.kie.reteoo.AlphaNode.

The Parser will invoke this method at the beginning of every non-hashed Alpha in the Network; there will be a corresponding endNonHashedAlphaNode() event for every startNonHashedAlphaNode() event. All of the node's decendants will be reported, in order, before the corresponding endNonHashedAlphaNode() event.

Specified by:

startNonHashedAlphaNode in interface NetworkHandler

Parameters:

alphaNode - non-hashed AlphaNode

See Also:

NetworkHandler.endNonHashedAlphaNode(org.drools.core.reteoo.AlphaNode)

endNonHashedAlphaNode

public void endNonHashedAlphaNode(AlphaNode alphaNode)

Description copied from interface: NetworkHandler

Receive notification of the end of a non-hashed org.kie.reteoo.AlphaNode.

The parser will invoke this method at the end of every alpha in the network; there will be a corresponding #startNonHashedAlphaNode(org.kie.reteoo.AlphaNode) event for every endNonHashedAlphaNode event.

Specified by:

endNonHashedAlphaNode in interface NetworkHandler

Parameters:

alphaNode - non-hashed AlphaNode

startBetaNode

public void startBetaNode(BetaNode betaNode)

Specified by:

startBetaNode in interface NetworkHandler

endBetaNode

public void endBetaNode(BetaNode betaNode)

Specified by:

endBetaNode in interface NetworkHandler

startLeftInputAdapterNode

public void startLeftInputAdapterNode(LeftInputAdapterNode leftInputAdapterNode)

Specified by:

startLeftInputAdapterNode in interface NetworkHandler

endLeftInputAdapterNode

public void endLeftInputAdapterNode(LeftInputAdapterNode leftInputAdapterNode)

Specified by:

endLeftInputAdapterNode in interface NetworkHandler

startHashedAlphaNodes

public void startHashedAlphaNodes(ClassFieldReader hashedFieldReader)

Description copied from interface: NetworkHandler

Receive notification of the a group of hashed org.kie.reteoo.AlphaNodes.

The Parser will invoke this method at the beginning of every groups of hashed Alphas in the Network; there will be a corresponding NetworkHandler.endHashedAlphaNodes(org.drools.core.base.ClassFieldReader) event for every startHashedAlphaNodes() event. The actual alpha nodes will be reported via the NetworkHandler.startHashedAlphaNode(org.drools.core.reteoo.AlphaNode, java.lang.Object) method, along with all of the node's decendants, in order, before the corresponding NetworkHandler.endHashedAlphaNode(org.drools.core.reteoo.AlphaNode, java.lang.Object) event.

Specified by:

startHashedAlphaNodes in interface NetworkHandler

Parameters:

hashedFieldReader - field reader that is used to access the hashed attribute

                               Object hashedValue)

Specified by:

endObjectTypeNode

public void endObjectTypeNode(ObjectTypeNode objectTypeNode)

Specified by:

endObjectTypeNode in interface NetworkHandler
