| |
| Thanks for your interest in this project. |
| |
| ## Project description |
| |
| Eclipse OCL™ is an implementation of the Object Constraint Language (OCL) OMG |
| standard for EMF-based models. Classic OCL Ecore/UML The Classic core OCL |
| component provides the following capabilities to support OCL integration: |
| Defines APIs for parsing and evaluating OCL constraints and queries on Ecore or |
| UML models. Defines Ecore and UML implementations of the OCL abstract syntax |
| model, including support for serialization of parsed OCL expressions. Provides a |
| Visitor API for analyzing/transforming the AST model of OCL expressions. |
| Provides an extensibility API for clients to customize the parsing and |
| evaluation environments used by the parser. The accompanying examples provide: A |
| Console for interactive evaluation of OCL expression on models. (Indigo) An |
| Impact Analyzer to support analysis and optimised re-evaluation. The core OCL |
| parser is generated by the LALR Parser Generator, a SourceForge project, |
| licensed under the EPL v1.0. Download it from the LPG home page. This site |
| includes the generator executable required to regenerate the parser code. |
| Unified Pivot OCL The Pivot OCL prototypes resolution of many oroblems in the |
| OMG 2.4 specification. An Xtext editor for OCL expressions (used by Papyrus and |
| the Console). An Xtext editor for OCL documents complemementing meta-models |
| (Complete OCL). An Xtext editor for OCLinEcore - OCL embedded in Ecore. An Xtext |
| editor for the OCL 'Standard' Library model. A UML-aligned Unified or Pivot OCL |
| meta-model supporting templates and reflection. An OCL evaluator exploiting the |
| extensible OCL library model. The accompanying examples provide: An Xtext |
| Console for interactive evaluation of OCL expression on models. Extensible |
| direct OCL to Java code generation A Validity View for detailed |
| Constraint/ModelElement validity visualization Extensible OCL debugger |
