| Specification of the <tt>Expressions</tt> package of the Object Constraint Lanuage |
| version 2.0 Abstract Syntax model. |
| |
| <h2>Package Specification</h2> |
| <p> |
| This package defines the API for the structure of parsed OCL expressions, as |
| described in the <tt>Expressions</tt> package of the OCL specification version |
| 2.0 with some extensions for this parser implementation. These extensions |
| include: |
| </p> |
| <ul> |
| <li>implementation of a {@link org.eclipse.ocl.utilities.Visitable Visitable} |
| interface to support the <tt>Visitor</tt> pattern for analysis and |
| transformation of expressions</li> |
| <li>implementation of a {@link org.eclipse.ocl.utilities.ASTNode} and related |
| interfaces for tracking the positions in the original input text of the |
| various parts of an expression</li> |
| <li>implementation of a {@link org.eclipse.ocl.utilities.TypedElement} |
| interface to define the name and type properties of expressions and |
| variables, inherited by these metaclasses from the UML, EMOF, or |
| Core::Basic metamodel respectively for CompleteOCL, EssentialOCL, and |
| BasicOCL</li> |
| </ul> |
| <p> |
| None of these extensions of the model affects the XMI serialization of OCL |
| expressions which, as much as possible, is conformant to the OCL specification. |
