Eclipse OCL New and Noteworthy items for the Indigo 3.1.0 release.
- 1 Milestone 2
- 2 Milestone 3
- 3 Milestone 4
- 4 Milestone 5
- 5 Milestone 6
- 6 Milestone 7
- 322159 Diagnose and workaround genmodel without Operation Reflection.
- 318119 Save no longer flashes XMI.
- 320689 Enum and DataType now conform to OclAny so that e.g. oclIsInvalid is no longer undefined.
- 321171 Reference opposite is now resolvable when the type is qualified.
- 321493 Unicode characters supported in annotations.
- 321518 Multi-line annotations supported.
- 321903 Supertype is now resolvable when qualified.
- 322675 OCLinEcore menu items now localized to OCLinEcore.
- 322886 CompleteOCL genmodel registration now findable.
- 330489 Fix content of singleton CollectionRange.
EMF 2.7.0 is a prerequisite as from M4.
- 331143 Support Query delegates.
The migration to the new architecture starts with M5, with a slightly early release mandated by alignment with Xtext 2.0 that becomes available at M5. Without migration, all the editors would be broken, with migration the OCLstdlib and OCLinEcore editors should be improved, although the CompleteOCL editor is temporarily broken. The new architecture features:
- a standard library defined by the OCL-2.4.oclstdlib model and its editor
- a org.eclipse.ocl.examples.pivot.standard_library extension point for custom libraries
- a Java class per operation/iteration/property in org.eclipse.ocl.examples.library...
- a pre-compiled version org.eclipse.ocl.examples.library.oclstdlib.OCLstdlib autogenerated by Acceleo
- an intermediate UML-aligned pivot model
- semantic as well as semantic validation in OCLstdlib and OCLinEcore (and EssentialOCL) editors
- a stream-lined evaluator aligned to the pivot model and library definition
- a Value hierarchy to wrap OCL semantics around Java objects
- an extensible/replaceable ValueFactory for alternate semantics
The new functionality is used automatically when using the editors.
The new functionality may be used programmatically by changing org.eclipse.ocl.ecore to org.eclipse.ocl.examples.pivot. This is only recommended to enthusiasts at present since the migration guide on detailed API evolution is not yet written.
The migration will continue in 3.1.0 Examples M6, M7 with
- CompleteOCL editor
- Use of EssentialOCL editor in the Interactive Console
- Support for UML
The migration will complete in 4.0 with
- promotion of org.eclipse.ocl.examples.pivot to org.eclipse.ocl.pivot
- redirection of "http://www.eclipse.org/emf/2002/Ecore/OCL" to the new functionality
- introduction of OCL to Java code generation
- org.eclipse.ocl, org.eclipse.ocl.ecore, org.eclipse.ocl.uml will remain substantially unchanged
- 251621 Support EAnnotations of missing Ecore eOpposites.
- 333032 Tuning up the API and Impl introduced by Bug 251621.
- 333241 Minimize impact of DefaultOppositeEndFinder
- 332400 Avoid redundant helper creation.
- 329980 Use @nooverride to clarify API.
- 328075 Hover text indicates static type signature.
- 191027 Inconsistent invalid numeric comparison issues resolved.
- 267223 Boolean operations involving null and invalid fixed.
- 282882 OCL 2.3 treatment of null/invalid comparisons.
- 283518 null in a collection is valid.
- 284129 Real/Integer treated as numbers for Tuple type deduction.
- 286929 invalid in a collection is invalid.
- 287052 static type information used to interpret eGet return.
- 287977 Numerous corner case operations issues fixed.
- 288566 OCL-invalid-with-reason/exception used in preference to Java-null/Java-exception.
- 290315 Java-null and OCL-null distinct.
- 291444 Conformance now defined once by library model rather than disparate code.
- 299862 OrderedSet.insertAt observes OCL equality semantics for duplicates.
- 299882 Increased Collection polymorphism fixes OrderedSet flatten
- 299967 Dynamic dispatch of operation overloads supported.
- 301352 Value hierarchy introduced to localize OCL equality with respect to Java equality semantics.
- 318047 UML-aligned pivot model introduced.
- 318048 Library operations factored out to one model-referenced Java class per operation.
- 290605 BigInteger, BigDecimal used to ensure larger number compliance.
- 332962 Query Delegate Text Viewer for OCL.
- 329336 EventManager added as pre-requisite for impact analyzer
Library and AST
- 152207 Support toString.
- 190461 OCL 2.3 spellings for UnlimitedNaturalLiteralExp.unlimitedNaturalSymbol.
- 196873 Introduce OCL standard library as a first class model.
- 216110 UML-aligned pivot model has OMG spelling of e.g. OclExpression.
- 246962 OrderedSet and Sequence operations shared via OrderedCollection.
- 259031 Support OclAny.oclType with reflection.
- 261008 UnlimitedNatural conforms to Integer.
- 281710 Support String +.
- 283052 Pivot model is UML-aligned.
- 290680 Collection conforms to OclAny.
- 291721 OclInvalid conforms to OclVoid and not-vice-versa.
- 299959 oclAsType conformance checked.
- 326534 Library model loaded from auto-generated code.
- 190150 Type expressions now parsed, declared and evaluated.
- 286737 Tuple parsing errors diagnosed better
- 288573 Library model used for iterator signature checking
- 288575 Qualified names more widely supported
- 296990 forAll/exists arguments now semantically checked against library model
- 299966 oclIsInState is now an ordinary operation
The Complete OCL editor is now useable.
All editors now support hover text feedback for type information.
Complete OCL and OCLinEcore editors support an additional parenthesized argument on an environment name in which a string experession may be specified to explain the invariant violation. The corresponding CompleteOCLEObjectValidator or OCLinEcoreEObjectValidator enables either Complete OCL documents of embedded OCL to participate in validating environments such as an Xtext editor.
An alternative Interactive Xtext Console may be used in which input uses Xtext Essential OCL editor and evaluation uses the new extensible pivot evaluator.
Complete OCL documents may be loaded to augment the evaluator.
An Impact Analyzer has been added to the examples feature. For a set of OCL expressions, based on an EMF Notification and in conjunction with the event manager already added in M5 it can efficiently determine which of the expressions may have changed its value and for which context objects. See org.eclipse.ocl.examples.impactanalyzer.ImpactAnalyzerFactory for an entry point. The Impact Analyzer is well prepared to deal with the hidden opposite properties introduced in M5.
