Method Detail

startObjectTypeNode

public void startObjectTypeNode(org.drools.core.reteoo.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:

NetworkHandler.endObjectTypeNode(org.kie.reteoo.ObjectTypeNode)

endObjectTypeNode

public void endObjectTypeNode(org.drools.core.reteoo.ObjectTypeNode objectTypeNode)

Specified by:

endObjectTypeNode in interface NetworkHandler

Overrides:

endObjectTypeNode in class NetworkHandlerAdaptor

startNonHashedAlphaNode

public void startNonHashedAlphaNode(org.drools.core.reteoo.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)

startBetaNode

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

Specified by:

startBetaNode in interface NetworkHandler

Overrides:

startBetaNode in class NetworkHandlerAdaptor

startWindowNode

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

Specified by:

startWindowNode in interface NetworkHandler

Overrides:

startWindowNode in class NetworkHandlerAdaptor

startLeftInputAdapterNode

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

Specified by:

startLeftInputAdapterNode in interface NetworkHandler

Overrides:

startLeftInputAdapterNode in class NetworkHandlerAdaptor

Returns a variable name based on the simple name of the specified class appended with the specified nodeId.

Parameters:

clazz - class whose simple name is lowercased and user as the prefix of the variable name

nodeId - id of org.kie.common.NetworkNode

Returns:

variable name
