  org.drools.core.reteoo.compiled.NetworkHandlerAdaptor
      org.drools.core.reteoo.compiled.SetNodeReferenceHandler

All Implemented Interfaces:

NetworkHandler

public class SetNodeReferenceHandler
extends NetworkHandlerAdaptor

This handler is used to create the member variable assignment statements section of a generated subclass of a CompiledNetwork#setNetworkNodeReference(org.kie.common.NetworkNode). Currently we only need to create member variable assignments for the following types of nodes:

Non-hashed AlphaNodes

LeftInputAdapterNodes

BetaNodes

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

Overrides:

startObjectTypeNode in class NetworkHandlerAdaptor

Parameters:

objectTypeNode - the object type node

See Also:

#endObjectTypeNode(org.kie.reteoo.ObjectTypeNode)

endObjectTypeNode

public void endObjectTypeNode(ObjectTypeNode objectTypeNode)

Specified by:

endObjectTypeNode in interface NetworkHandler

Overrides:

endObjectTypeNode in class NetworkHandlerAdaptor

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

Overrides:

startNonHashedAlphaNode in class NetworkHandlerAdaptor

Parameters:

alphaNode - non-hashed AlphaNode

startBetaNode

public void startBetaNode(BetaNode betaNode)

Specified by:

startBetaNode in interface NetworkHandler

Overrides:

startBetaNode in class NetworkHandlerAdaptor

startLeftInputAdapterNode

public void startLeftInputAdapterNode(LeftInputAdapterNode leftInputAdapterNode)

Specified by:

Overrides:

startLeftInputAdapterNode in class NetworkHandlerAdaptor
