Method Detail

startObjectTypeNode

void startObjectTypeNode(org.drools.core.reteoo.ObjectTypeNode objectTypeNode)

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.

Parameters:

objectTypeNode - the object type node

See Also:

#endObjectTypeNode(org.kie.reteoo.ObjectTypeNode)

startNonHashedAlphaNode

void startNonHashedAlphaNode(org.drools.core.reteoo.AlphaNode alphaNode)

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.

Parameters:

alphaNode - non-hashed AlphaNode

See Also:

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

endNonHashedAlphaNode

void endNonHashedAlphaNode(org.drools.core.reteoo.AlphaNode alphaNode)

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.

Parameters:

alphaNode - non-hashed AlphaNode

startBetaNode

void startBetaNode(org.drools.core.reteoo.BetaNode betaNode)

endBetaNode

void endBetaNode(org.drools.core.reteoo.BetaNode betaNode)

startWindowNode

void startWindowNode(org.drools.core.reteoo.WindowNode windowNode)

endWindowNode

void endWindowNode(org.drools.core.reteoo.WindowNode windowNode)

startLeftInputAdapterNode

void startLeftInputAdapterNode(org.drools.core.reteoo.LeftInputAdapterNode leftInputAdapterNode)

endWindowNode

void endWindowNode(org.drools.core.reteoo.LeftInputAdapterNode leftInputAdapterNode)

startHashedAlphaNodes

void startHashedAlphaNodes(org.drools.core.rule.IndexableConstraint hashedFieldReader)

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 endHashedAlphaNodes(org.drools.core.rule.IndexableConstraint) event for every startHashedAlphaNodes() event. The actual alpha nodes will be reported via the startHashedAlphaNode(org.drools.core.reteoo.AlphaNode, java.lang.Object) method, along with all of the node's decendants, in order, before the corresponding endHashedAlphaNode(org.drools.core.reteoo.AlphaNode, java.lang.Object) event.

Parameters:

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