Description

Interface Summary

DataObserver	Use DataObserver to observe the changes in the data used by a Engine instance.
Engine	Use this Engine interface to parametrize and run an Engine instance.
EngineData	An EngineData stores the values used as the parameters of an engine.
EngineDefinition	Use EngineDefinition to create Engine instances.
EngineInput	Use EngineInput to parameterize Engine execution.
EngineObserver	Use an EngineObserver instance to observe the overall state of an Engine.
EngineOutput	An EngineOutput object is produced when an Engine is executed.
EngineSignature	EngineSignature represents the signature of an Engine.
EngineSignature.Parameter	Parameter represents a parameter in an EngineSignature instance.
EngineWithWorkingMemory	EngineWithWorkingMemory represents a rule engine instance.
EngineWithWorkingMemoryInput	The rule engine input is used to parameterize a rule engine execution.
EngineWithWorkingMemoryOutput	The rule engine output is produced when a rule engine is executed.
NoteObserver	NoteObserver represents an Observer for notes.
RunningEngine	Use RunningEngine inside a running engine, such as rules, tasks, or B2X.
RunningEngineWithWorkingMemory	Use the RunningEngineWithWorkingMemory interface only inside a RunningEngine.

Class Summary

EngineVersion

Use EngineVersion to identify the version of IBM Decision Engine that you are using.

Enum Summary

EngineState	The EngineState enumeration describes the current state of an Engine instance.
InoutModifier	InoutModifier represents the signature parameter modifier.

Package com.ibm.rules.engine.runtime Description

Engine runtime API.

Overview

The EngineDefinition instance describes the rules or tasks, the Engine object executes the rules.

The following figure gives an overview of the API:

Engine definition

An engine definition is similar to a Classic Rule Engine ruleset. Using an engine definition you:

• access rules or tasks
• create an executable engine

An engine definition can be loaded using an EngineLoader. The engine definition may be parametrized by providing an external B2X, a classloader and other optional parameters.

Engine

In IBM Decision Server, an engine is an Engine instance. This class, and its subclasses, contain all the methods required to control the engine. An Engine object is always attached to an EngineDefinition instance. Note that there is no inverse relationship, so only your reference to an Engine instance will keep it in memory.
