 <p>Juno introduced an experimental ability to replace the delegated interpreted execution of OCL by direct execution of compiled Java code. This facility has been substantially improved and tested for the Kepler release.</p>
 <p>Optimisations for Luna included inlining the bodies directly into the EMF Impl classes. </p>
 <p>Mars has useful fixes and benefits from safe navigation analyses.</p>
 <p>Further optimisations are scheduled for future releases.</p>

 <p>OCL embedded in Ecore can be executed with either the Classic evaluator or the new Pivot evaluator depending on the URI used to define the embedded EAnnotations. This preference determines the URI written to Ecore files when no URI was previously in use.</p>
 <p>Selecting
 					<code class="code">http://www.eclipse.org/emf/2002/Ecore/OCL</code> makes no choice and so defers to the user&rsquo;s
 					<a class="link" href="UserInterface.html#DefaultDelegation" title="http://www.eclipse.org/emf/2002/Ecore/OCL">run-time delegation choice</a>.
 				</p>
 <p>Selecting
 					<code class="code">http://www.eclipse.org/emf/2002/Ecore/OCL/Pivot</code> is recommended since the OCLinEcore editor and Pivot evaluator both use the Xtext parser. This should avoid problems whereby not all facilities of the new Pivot grammar are supported by the Classic grammic or LPG evaluator.
 				</p>
 <p>Selecting
 					<code class="code">http://www.eclipse.org/emf/2002/Ecore/OCL/LPG</code> may be appropriate if evaluation using the classic LPG evaluator is important.

	<p>Juno introduced an experimental ability to replace the delegated interpreted execution of OCL by direct execution of compiled Java code. This facility has been substantially improved and tested for the Kepler release.</p>
	<p>Optimisations for Luna included inlining the bodies directly into the EMF Impl classes. </p>
	<p>Mars has useful fixes and benefits from safe navigation analyses.</p>
	<p>Further optimisations are scheduled for future releases.</p>

	<p>Selecting the default delegation mode retains the Helios and Indigo functionality whereby

	<p>Disclaimer: the generated code is experimental has yet to be optimized and so is only about five times faster than the interpreted execution. </p>

	<p>OCL embedded in Ecore can be executed with either the Classic evaluator or the new Pivot evaluator depending on the URI used to define the embedded EAnnotations. This preference determines the URI written to Ecore files when no URI was previously in use.</p>
	<p>Selecting
	<code class="code">http://www.eclipse.org/emf/2002/Ecore/OCL</code> makes no choice and so defers to the user’s
	<a class="link" href="UserInterface.html#DefaultDelegation" title="http://www.eclipse.org/emf/2002/Ecore/OCL">run-time delegation choice</a>.
	</p>
	<p>Selecting
	<code class="code">http://www.eclipse.org/emf/2002/Ecore/OCL/Pivot</code> is recommended since the OCLinEcore editor and Pivot evaluator both use the Xtext parser. This should avoid problems whereby not all facilities of the new Pivot grammar are supported by the Classic grammic or LPG evaluator.
	</p>
	<p>Selecting
	<code class="code">http://www.eclipse.org/emf/2002/Ecore/OCL/LPG</code> may be appropriate if evaluation using the classic LPG evaluator is important.
