Constructor Detail

ReteooBuilder

public ReteooBuilder()

ReteooBuilder

public ReteooBuilder(InternalRuleBase ruleBase)

Construct a Builder against an existing Rete network.

Method Detail

addRule

public void addRule(Rule rule)
             throws InvalidPatternException

Add a Rule to the network.

Parameters:

rule - The rule to add.

Throws:

RuleIntegrationException - if an error prevents complete construction of the network for the Rule.

InvalidPatternException

addEntryPoint

public void addEntryPoint(String id)

addNamedWindow

public void addNamedWindow(WindowDeclaration window)

getWindowNode

public WindowNode getWindowNode(String name)

getIdGenerator

public ReteooBuilder.IdGenerator getIdGenerator()

getTerminalNodes

public BaseNode[] getTerminalNodes(Rule rule)

getTerminalNodes

public BaseNode[] getTerminalNodes(String ruleName)

getTerminalNodes

public Map<String,BaseNode[]> getTerminalNodes()

removeRule

public void removeRule(Rule rule)

resetMasks

public void resetMasks(RuleRemovalContext context)

Rule removal now keeps a list of all the visited nodes. We iterate each of those to find the nodes still in use, who's inferred mask is now stale. For each node we find the tip, which is either BetaNode or RuleTerminalNode and re initialise the inferred mask, which will trickle back up to the OTN

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

Specified by:

readExternal

public void readExternal(ObjectInput in)
                  throws IOException,
