Consequently when Eclipse UML moved from to UML 2.4 support (4.0.0) and again to UML 2.5 (5.0.0) a corresponding change was forced on the Classic UML support and this is the number that then applies to the whole of Eclipse OCL. However the Ecore dependencies are unchanged and so Ecore dependent releases have advanced more slowly; 3.2 accompanying 4.0 and now 3.5 accompanying 6.0.</fo:block><fo:block space-before.optimum="0.4em" space-before.minimum="0.3em" space-before.maximum="0.5em">This is probably just as confusing for the developers as for consumers.

Unboxed values (the natural Ecore and Java representation) are used wherever OCL and Java have compatible semantics, that is for Boolean, String, null, invalid/exception and EObjects that are not Types. Boxed polymorphic value representations are used wherever OCL and Java semantics differ, that is for IntegerValue, RealValue, CollectionValue, TupleValue and TypeValue. This avoids unnecessary conversion costs, but requires many instanceof tests to compensate for the lack of Value polymorphism.

+and validated and how expressions can be evaluated, all without generating any Java code. The OCLinEcore support
+provides the requisite Ecore EAnnotations to ensure that the dynamic execution of EMF activates an OCL
+interpreter where OCL functionality is required.
 
-Exactly the same facilities are available if you do generate Java code and as a result you gain some speed benefits. By default, in the Eclipse OCL 6.4.0 (Photon) release the generated Java code for OCL is interpreted and so the speed gains occur only for the EMF models.
-In the "Code Generation Tutorial":#CodeGenerationTutorial, a preliminary release of 
-the OCL to Java code generator is described, giving an approximately five-fold speed improvement
-and eliminating the need for run-time compilation.
+Exactly the same facilities are available if you generate Java code for the Ecore model and as a result you gain some speed benefits. You have two choices for the realization of the OCL embedded with Ecore models.
+
+* Generate Java code within the *Impl classes
+* Delete for interpretation at run-time
+
+The first newer approach takes longer to generate the model since the OCL is compiled to Java incurring parser overheads at compile-time. However the OCL runs approximately five times faster and has fewer dependencies since no parsing is necessary at run-time. This approach is described In the "Code Generation Tutorial":#CodeGenerationTutorial.
+
+The second older approach embeds the OCL in the Java as unparsed stings so that parsing occurs overheads at run-time. The generated Java is smaller since the executable Java for OCL is larger than uncompiled strings. 
+
+We continue here with the older approach for which delegation to yyje interpreter is selected as a root *Window->Preferences->OCL* relaization preference.
 
 Generating Java code is exactly the same as for any other EMF project. (Prior to EMF 2.8, there was one important difference; you must explicitly set *Operation Reflection* to true. The default for this changed to true in EMF 2.8.)
