                     boolean alphaNetContainsHashedField)

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)

startBetaNode

public void startBetaNode(BetaNode betaNode)

Specified by:

startBetaNode in interface NetworkHandler

Overrides:

startBetaNode in class NetworkHandlerAdaptor

startWindowNode

public void startWindowNode(WindowNode windowNode)

Specified by:

startWindowNode in interface NetworkHandler

Overrides:

startWindowNode in class NetworkHandlerAdaptor

startLeftInputAdapterNode

public void startLeftInputAdapterNode(LeftInputAdapterNode leftInputAdapterNode)

Specified by:

startLeftInputAdapterNode in interface NetworkHandler

Overrides:

startLeftInputAdapterNode 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

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

Overrides:

endNonHashedAlphaNode in class NetworkHandlerAdaptor

Parameters:

alphaNode - non-hashed AlphaNode

startHashedAlphaNodes

public void startHashedAlphaNodes(IndexableConstraint indexableConstraint)

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.rule.IndexableConstraint) 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

Overrides:

startHashedAlphaNodes in class NetworkHandlerAdaptor

Parameters:

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