Exception Summary

AbleParException

This class defines the Able rule Parser exception.

Package com.ibm.able.rules Description

The rules package defines the ABLE rule language; various inferencing engines; objects and APIs for creating and running rulesets under program control. The major classes include the AbleRuleSet bean which provides the bulk of the public APIs, the AbleRule base class (and extensions) and the AbleInferenceEngine class (and extensions). This package makes heavy use of the ABLE data package for literal and variable representations.

The ABLE rule language is documented here.
