OCL
Revision as of 06:37, 10 December 2010 by Adolfosbh.opencanarias.com (Talk | contribs) (→Release Engineering)
OCL is an implementation of the Object Constraint Language (OCL) OMG standard for EMF-based models.
The OCL component provides the following capabilities to support OCL integration:
- Defines APIs for parsing and evaluating OCL constraints and queries on EMF 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 additional OCL Examples and Editors component provides interactive support for OCL:
- Provides an Interactive OCL Console to evaluate queries on models.
- Provides an OCLinEcore Xtext editor for OCL embedded in an Ecore meta-model.
- Provides a CompleteOCL editor for an OCL document complementing a meta-model.
- Provides an EssentialOCL editor for individual OCL expressions.
The 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.
