Constructor Details

InferenceRuleVisitor

public InferenceRuleVisitor(RuleGraph graph,
 IProject project,
 IMetaModel model,
 IRuleFactory ruleFactory,
 IParserFactory parserFactory,
 IConnectionManager connectionManager,
 IReportingDS report)

Constructs a rule visitor with the required parameters.

Parameters:

graph - The rule graph that should be used to add the rules to.

project - the project

model - The metamodel definition of the current application.

ruleFactory - The rule factory that should be used to locate external rules.

parserFactory - Factory that may be used to parse rules.

connectionManager - The connection manager used to locate connections.

report - The report that should be used to add error or warnings to.

Method Details

addSource

public void addSource(IInferenceRule rule)

Description copied from interface: ISourceVisitor

This method may be used to add a custom inference rule to the rule engine.

Specified by:

addSource in interface ISourceVisitor

Parameters:

rule - The custom implementation of the inference rule interface.

addExternalSource

public void addExternalSource(IExternalRuleDS externalRule)

Description copied from interface: ISourceVisitor

The data layer may invoke this method to add an external inference rule. The rule factory will be used to locate the implementation for the inference rule.

Specified by:

addExternalSource in interface ISourceVisitor

Parameters:

externalRule - Data source providing information about the external inference rule.

addTable

public void addTable(IDecisionTableDS source)

Description copied from interface: ISourceVisitor

This method may be used to add a decision table to the rule engine.

Specified by:

addTable in interface ISourceVisitor

Parameters:

source - Data source capable of providing the data needed to initialize a decision table.

addRule

public void addRule(IBusinessRuleDS source)

Description copied from interface: ISourceVisitor

This method may be used to add a business rule (IF-THEN rule) to the rule engine.

Specified by:

addRule in interface ISourceVisitor

Parameters:

source - Data source capable of providing the data needed to initialize a business rule.

addDefaultRule

public void addDefaultRule(IDefaultRuleDS defaultDS)

Description copied from interface: ISourceVisitor

This method may be used to add a default rule to the rule graph. Default rules are different from normal inference rules as they may source a value for only a single attribute, and will be executed after all the other rules have been evaluated.

Specified by:

addDefaultRule in interface ISourceVisitor

Parameters:

defaultDS - Data source providing the information for the default rule.

addDefaultTable

protected void addDefaultTable(IExpressionParser parser,
 String attribute,
 IDecisionTableDS source)

addDataRule

public void addDataRule(IDataRuleDS dataRule)

Description copied from interface: ISourceVisitor

This method may be used to add a data rule to the rule engine.

Specified by:

addDataRule in interface ISourceVisitor

Parameters:

dataRule - Data source capable of providing the data needed to initialize a data rule.
