<P>
Provides static factory methods that return CDO-scoped <A HREF="../../../../../org/eclipse/emf/cdo/compare/CDOCompareUtil.CDOComparison.html" title="class in org.eclipse.emf.cdo.compare"><CODE>comparisons</CODE></A>.
 <p>
 Two different <CODE>scopes</CODE> are supported:
 <ul>
 <li><A HREF="../../../../../org/eclipse/emf/cdo/compare/CDOCompareUtil.CDOComparisonScope.AllContents.html" title="class in org.eclipse.emf.cdo.compare"><CODE>CDOComparisonScope.AllContents</CODE></A> takes an arbitrary <A HREF="../../../../../org/eclipse/emf/cdo/CDOObject.html" title="interface in org.eclipse.emf.cdo"><CODE>object</CODE></A> (including <A HREF="../../../../../org/eclipse/emf/cdo/eresource/CDOResourceNode.html" title="interface in org.eclipse.emf.cdo.eresource"><CODE>resource nodes</CODE></A>)
 and returns <CODE>matches</CODE> for <b>all</b> elements of its <A HREF="http://download.eclipse.org/modeling/emf/emf/javadoc/2.8.0/org/eclipse/emf/ecore/EObject.html?is-external=true#eAllContents()" title="class or interface in org.eclipse.emf.ecore"><CODE>content tree</CODE></A>. This scope has the advantage that the comparison can
 be rooted at specific objects that are different from (below of) the root resource. The disadvantage is that all the transitive children of this specific object are
 matched, whether they differ or not. Major parts of huge repositories can be loaded to the client side easily, if no attention is paid.
 The following methods return comparisons that are based on this scope algorithm:
 <ul>
 <li><A HREF="../../../../../org/eclipse/emf/cdo/compare/CDOCompareUtil.html#compare(org.eclipse.emf.ecore.EObject, org.eclipse.emf.cdo.common.branch.CDOBranchPoint)"><CODE>compare(EObject, CDOBranchPoint)</CODE></A>
 <li><A HREF="../../../../../org/eclipse/emf/cdo/compare/CDOCompareUtil.html#compare(org.eclipse.emf.ecore.EObject, org.eclipse.emf.cdo.common.branch.CDOBranchPoint, boolean)"><CODE>compare(EObject, CDOBranchPoint, boolean)</CODE></A>
 </ul>
 <li><A HREF="../../../../../org/eclipse/emf/cdo/compare/CDOCompareUtil.CDOComparisonScope.Minimal.html" title="class in org.eclipse.emf.cdo.compare"><CODE>CDOComparisonScope.Minimal</CODE></A> takes a <A HREF="../../../../../org/eclipse/emf/cdo/view/CDOView.html" title="interface in org.eclipse.emf.cdo.view"><CODE>view</CODE></A>/<A HREF="../../../../../org/eclipse/emf/cdo/transaction/CDOTransaction.html" title="interface in org.eclipse.emf.cdo.transaction"><CODE>transaction</CODE></A>
 and returns <CODE>matches</CODE> only for the <b>changed</b> elements of the entire content tree of its <A HREF="../../../../../org/eclipse/emf/cdo/view/CDOView.html#getRootResource()"><CODE>root resource</CODE></A>.
 The advantage of this scope is that CDO-specific mechanisms are used to efficiently (remotely) determine the set of changed objects. Only those and their container
 objects are considered as matches, making this scope scale seamlessly with the overall size of a repository.
 The following methods return comparisons that are based on this scope algorithm:
 <ul>
 <li><A HREF="../../../../../org/eclipse/emf/cdo/compare/CDOCompareUtil.html#compare(org.eclipse.emf.cdo.view.CDOView, org.eclipse.emf.cdo.common.branch.CDOBranchPoint)"><CODE>compare(CDOView, CDOBranchPoint)</CODE></A>
 <li><A HREF="../../../../../org/eclipse/emf/cdo/compare/CDOCompareUtil.html#compare(org.eclipse.emf.cdo.view.CDOView, org.eclipse.emf.cdo.common.branch.CDOBranchPoint, boolean)"><CODE>compare(CDOView, CDOBranchPoint, boolean)</CODE></A>
 </ul>
 </ul>
 The <CODE>right side</CODE> of a comparison is specified as a <A HREF="../../../../../org/eclipse/emf/cdo/common/branch/CDOBranchPoint.html" title="interface in org.eclipse.emf.cdo.common.branch"><CODE>CDOBranchPoint</CODE></A> which, among others, can be another <A HREF="../../../../../org/eclipse/emf/cdo/view/CDOView.html" title="interface in org.eclipse.emf.cdo.view"><CODE>CDOView</CODE></A>
 (which then is not closed when the comparison is closed) or a <A HREF="../../../../../org/eclipse/emf/cdo/common/commit/CDOCommitInfo.html" title="interface in org.eclipse.emf.cdo.common.commit"><CODE>CDOCommitInfo</CODE></A>. The <CODE>origin side</CODE> of a comparison is
 automatically <A HREF="../../../../../org/eclipse/emf/cdo/spi/common/branch/CDOBranchUtil.html#getAncestor(org.eclipse.emf.cdo.common.branch.CDOBranchPoint, org.eclipse.emf.cdo.common.branch.CDOBranchPoint)"><CODE>determined</CODE></A> by inspecting the <A HREF="../../../../../org/eclipse/emf/cdo/common/branch/CDOBranch.html" title="interface in org.eclipse.emf.cdo.common.branch"><CODE>branch tree</CODE></A> and used if its different from the left or right side.
 <p>
 The comparions returned from these factory methods are all of the type <A HREF="../../../../../org/eclipse/emf/cdo/compare/CloseableComparison.html" title="interface in org.eclipse.emf.cdo.compare"><CODE>CloseableComparison</CODE></A> and the caller is responsible to call <A HREF="../../../../../../../org.eclipse.net4j.util.doc/javadoc/org/eclipse/net4j/util/collection/Closeable.html?is-external=true#close()" title="class or interface in org.eclipse.net4j.util.collection"><CODE>Closeable.close()</CODE></A>
 on them when they're not needed anymore. The reason is that the scopes may or may not open a number of addional <A HREF="../../../../../org/eclipse/emf/cdo/view/CDOView.html" title="interface in org.eclipse.emf.cdo.view"><CODE>views</CODE></A> on the local <A HREF="../../../../../org/eclipse/emf/cdo/session/CDOSession.html" title="interface in org.eclipse.emf.cdo.session"><CODE>session</CODE></A>
 that need to be closed at some point.
 <p>
 The <CODE>matcher</CODE> used by the comparisons is based on an <A HREF="../../../../../org/eclipse/emf/cdo/compare/CDOCompareUtil.CDOIDFunction.html" title="class in org.eclipse.emf.cdo.compare"><CODE>ID function</CODE></A> that considers the <A HREF="../../../../../org/eclipse/emf/cdo/common/id/CDOID.html" title="interface in org.eclipse.emf.cdo.common.id"><CODE>CDOID</CODE></A>s of the <A HREF="../../../../../org/eclipse/emf/cdo/CDOObject.html" title="interface in org.eclipse.emf.cdo"><CODE>objects</CODE></A>.
 <A HREF="../../../../../org/eclipse/emf/cdo/eresource/CDOResource.html" title="interface in org.eclipse.emf.cdo.eresource"><CODE>Resources</CODE></A> and <A HREF="../../../../../org/eclipse/emf/cdo/eresource/CDOResourceFolder.html" title="interface in org.eclipse.emf.cdo.eresource"><CODE>folders</CODE></A> are treated as normal <A HREF="http://download.eclipse.org/modeling/emf/emf/javadoc/2.8.0/org/eclipse/emf/ecore/EObject.html?is-external=true" title="class or interface in org.eclipse.emf.ecore"><CODE>EObject</CODE></A>s.

This scope has the advantage that the comparison can
 be rooted at specific objects that are different from (below of) the root resource. The disadvantage is that all the transitive children of this specific object are
 matched, whether they differ or not. Major parts of huge repositories can be loaded to the client side easily, if no attention is paid.
