| Definition of the OCL Helper API for syntax completion support and a simplified |
| parsing model for embedded OCL constraints and expressions. |
| |
| <h2>Package Specification</h2> |
| <p> |
| The primary interface in this package is the |
| {@link org.eclipse.ocl.helper.OCLHelper}, which provides OCL syntax |
| completion assistance and parsing support. Instances are obtained from the |
| {@link org.eclipse.ocl.OCL} class. |
| </p> |
| <p> |
| OCL code completion suggestions are represented as |
| {@link org.eclipse.ocl.helper.Choice}s, which indicate the name of a |
| language construct, a description, and the |
| {@linkplain org.eclipse.ocl.helper.ChoiceKind kind} of construct. |
| </p> |
| <p> |
| The <code>OCLHelper</code> also provides a simple API for parsing constraints |
| and expressions embedded in models: |
| </p> |
| <ul> |
| <li>invariants and additional attribute/operation definitions in a |
| classifier context</li> |
| <li>pre/post conditions and body conditions in an operation context</li> |
| <li>initial- and derived-value expressions in an attribute context</li> |
| </ul> |
| <p> |
| The helper also supports the simultaneous definition and value binding of |
| "global" variables, to support injection of custom variables into OCL |
| expressions. |
| </p> |
