Eclipse OCL New and Noteworthy items for the Oxygen 6.3.0 release.

Release Overview

This minor release fixes many bugs and provides enhanced extensibility for OCL-based applications such as QVT.

The Oxygen release is installable on Mars, Neon and Oxygen platforms provided Xtext 2.9 or greater is also installed.

Milestone 1

Classic Console

• 499347 Obscure NPE for ResourceSet-less Resources fixed

Pivot

• 484231 Repeated Complete OCL validations are no longer ignored
• 496341 Better diagnosis of unresolved proxies during AS2CS serialization
• 496768 Save of Collection type oclAsType arguments no longer gives an unresolved proxy
• 496810 'self' no longer escaped in serialized OCL expressions
• 496810 parameter names no longer qualified in serialized OCL expressions

Pivot UML

• 496210 allInstances() may now be used for Signals
• 496251 OCL expressions now generally available for UMLElement again
• 496383 Association-derived Pivot properties have an ESObject back link again
• 498970 Obscure NPE for PackageImport labels fixed

Milestone 2

Library

• 499816 and2/implies2/not2/or2/xor2 support explicitly 2-valued Booleans

Pivot Evaluation

• 471240 Shadow objects are now singletons
• 491264 EvaluationCache now suppresses operation re-evaluations

CG

• 500817 Inlining suppressed for non-final operations
• 500520 Operation::isTransient suppresses operation evaluation caching

Milestone 3

Pivot UML

• 506191 Multi-language OpaqueExpressions now use the OCL language

Milestone 4

Pivot

• 474537 Operation call return types are now correctly specialized
• 507557 All class-typed properties have opposites - no exclusions for transient etc
• 507628 OCL Validation detects null feature types/names.
• 507658 LetVariable, IteratorVariable, ResultVariable introduced.

Pivot UML

• 507406 Evaluations of redefined properties with changed multiplicities no longer fail

Extensibility

• 412341 Extended validation may be merged into extended AS models
• 507425 Extended generation re-uses rather than corrupts base model elements
• 507843 Extended genmodels may use patform URIs

Milestone 5

Three subtle semantic changes.

The Pivot null-analysis exploits the common practice and UML mandate that Collections are null-free. If null content is required it must be declared.

The Pivot invalid-analysis now treats machine failures as fatal rather than invalid. Consequently a property navigation cannot return invalid, and a machine failure cannot be processed using oclIsInvalid().

The Pivot code generator is moving towards efficient inlining of Boolean operations. and/implies/not/or/xor can no longer be redefined.

Ecore

• 495621 User-defined Primitive types are now merged with regular Primitive types
• 509858 Opposite role name EAnnotation corrected for sensibly named Collection
• 510180 A zero lower bound for an EBoolean is ignored. It is always 1; not-null.

Pivot

• 467339 Null safety analysis now considers simple Boolean if/implies etc data flow
• 480060 elseif works
• 492293 Collections are null-free unless declared otherwise
• 495621 OCL can now be parsed in a user specified context
• 507628 OCL Validation detects null class names.
• 507628 OCL Validation detects that the closure body is assignable to the result.
• 509308 Shadow DataType elements may use a "value=" part with an arbitrary OCL expression.
• 509616 Collection return types are now modeled more accurately.
• 509670 Performance of Bags improved.
• 509713 Property navigation can no longer provide an invalid result.
• 510729 OCL library Pivot elements now have a stable corresponding Ecore element

Code Generator

• 509211 Constraints may now use lets to share common code for a tuple return of status and message
• 509222 Constraints may now use "context" as a variable name
• 509661 Boolean operations are not redefinable

Milestone 6

OCLinEcore

• 512452 OCL in Ecore validation now detects OCL validation as well as OCL parsing errors

Pivot

• 511536 The ParserContext is now extensible.
• 511782 Bounded collection bounds e.g. Set(T[4]) are now consistently inside the parentheses.
• 511992 Collections are never null (although they may have null elements)
• 512758 Collection multiplicities are more accurate for conversions such as oclAsSet().

Pivot UML

• 512448 Spurious no-invocationDelegates diagnosis for invariants removed
• 512449 Only the most recent stereotype EPackage is validated
• 512454 OCL in UML validation now detects OCL validation as well as OCL parsing errors
• 512545 Validation diagnostics now have UML context and so display sensibly in Papyrus
• 512553 Static class operations may now be used
• 512726 Navigable opposite properties may now be used
• 512910 Opposite properties of static profile stereotypes may now be used

Milestone 7

OCLinEcore

• 516274 Type bounds on Template Parameters are no longer lost when saving as Ecore

Pivot

• 515605 Unambiguous opposite properties no longer behave intermittently if their unqualified name is ambiguous.

Pivot UML

• 513773 Use of an Association end name no longer gices a ClassCastException
• 513824 Qualified names may now be partially qualified
• 514353 Associations nested within Classes are no longer ignored
• 516285 References to nested packages with URIs below packages with null URIs are no longer unresolved

Code Generation

• 514527 GenModel interface/implementation suffixes are now respected

Java 9, Guava 21

• 513659 Should run using Guava 21
• 513663 Should run on a Java 9 platform

Milestone 7a

This cures a potential problem for users auto-generating Java code from OCL enriched models.

• 516797 @NonNull compilation errors detected by JDT M7 fixed

OCLinEcore

• 516301 OCL comments and GenModel documentation are now spliced as a single documnetation

• 515050 Ambiguities due to same-named meta-properties are now resolved
• 516963 Unresolved proxies when editing AS files now diagnosed
