Description

Interface Summary

IlrAgendaFilter	This interface is used to select rule instances in the agenda.
IlrAssertDemon	If the class of an object implements IlrAssertDemon, then the method that this interface defines is called when the object is asserted.
IlrCollection	This interface represents a collection in the ILOG Rule Language (IRL).
IlrEvent	This interface defines an event handled by the event management feature.
IlrExceptionHandler	An exception handler manages the way an execution context processes the exceptions thrown during the execution of rules.
IlrPriorityValues	This interface defines constants that are used in rule priorities.
IlrRetractDemon	If the class of an object implements IlrRetractDemon, then the method that this interface defines is called when the object is retracted from a context.
IlrRuleTaskRunner	This interface specifies a rule task runner.
IlrTaskRunner	This is the base interface of a task runner.
IlrTool	The IlrTool interface.
IlrTupleIterator	This interface specifies a tuple iterator.
IlrUpdateDemon	If the class of a modified object in a context implements this interface, then the method that this interface defines is called.

Class Summary

IlrCompiledTaskRefactoring	This class is there to specify the refactoring of a compiled task.
IlrContext	IlrContext is the base class of all the execution contexts.
IlrDefaultCollector	This class defines the collector used by a collect condition for which a collector is not provided.
IlrDefaultEvent	This class provides a wrapping mechanism for objects asserted as an event but whose class does not implement the IlrEvent interface.
IlrFunction	Instances of the IlrFunction class are functions in a ruleset.
IlrPackage	This class models the packages in the IRL language.
IlrPackageFilter	This class implements an agenda filter that tests whether a rule belongs to a package.
IlrParameterMap	Implements a structure for storing parameter values to set or get from ruleset variables.
IlrPropertyFilter	This class implements an agenda filter.
IlrRule	Instances of the IlrRule class are rules in a ruleset.
IlrRuleInstance	IlrRuleInstance objects are rule instances currently fireable in the agenda of the context.
IlrRuleset	An instance of this class represents a ruleset which is an entity that manages a set of rules.
IlrRulesetArchiveBuilder	This class is a ruleset archive builder.
IlrRulesetArchiveParser	This class is a parser of ruleset archives.
IlrRulesetParameter	This class implements a ruleset parameter that is a tuple <type, name, modifier> which is in term of types a tuple <IlrType, String, int>.
IlrRuntime	This class is a utility for displaying information about memory and elapsed time used to execute a section of code.
IlrTask	This abstract class represents the super class of a task definition of the IRL language.
IlrToolAdapter	The IlrToolAdapter class.
IlrToolDecorator	The IlrToolDecorator class is useful to customize an already defined IlrTool.
IlrToolFactory	The IlrToolFactory abstract class.
IlrUtil	This class contains some static methods to extract contents of streams into different forms convenient for JRules.
IlrWatchEvent	This class is used to represent the object bound in a wait condition.

Exception Summary

IlrBadContextException	This exception is thrown when there is a mismatch between execution context classes.
IlrNoSuchFunctionException	This exception is thrown by the method IlrContext.invokeFunction(String,java.lang.Object[]) when the invoked function is unknown.
IlrRulesetLockedException	This exception is returned by a modification method of the ruleset when the ruleset is locked.
IlrRuntimeException	This exception is the base class of all the runtime exceptions thrown by the rule engine during the execution of rules.
IlrSystemRuntimeException	This exception is thrown when JRules detects an error at runtime.
IlrToolConnectionException	This exception is thrown when a connection to an IlrTool fails.
IlrUndefinedMainTaskException	This exception is thrown when the execution of a ruleflow whose main task has not been defined is required.
IlrUndefinedTaskException	This exception is thrown when a reference is done to a task that has not been defined in the ruleset.
IlrUserActionException	This exception is thrown by the methods IlrContext.send(java.lang.Object) and IlrContext.send(java.lang.String,java.lang.Object).
IlrUserRuntimeException	This exception is thrown each time JRules detects an error at runtime.

Package ilog.rules.engine Description

Provides the core classes of the JRules rule engine, otherwise known as an inference engine. The IlrRuleset class is used to define rules, and the IlrContext class is used to execute the rules. These two classes are the main classes of the rule engine.

This package also offers the interfaces that allow users to define customized behaviors within the rule engine, such as demons and collections of objects.
