This extension point allows to contribute Java completion proposal computers to participate in the content assist process of the Java editor. The fully qualified identifier of the target extension point The identifier of the extension instance, unique within the declaring plug-in (the plug-in's identifier will be prepended to form a platform-wide unique id) The optional name of the extension instance A proposal computer contribution. If no partition types are specified, the computer is added to all partition types. The name of the class that implements the contributed computer. The class must be public and implement <samp>descent.ui.text.java.IJavaCompletionProposalComputer</samp> and must have a public 0-argument constructor. If the attribute is set to "true" it will force this plug-in to be loaded on content assist invocation. The id of a <tt>proposalCategory</tt> A Java partition type for which the specified computer can provide completion proposals. See <code>IDocument.DEFAULT_CONTENT_TYPE</code> and <code>IJavaPartitions</code> for valid values. A proposal category contribution defines categories of proposals used to group them in the UI. The optional icon of the category, which can be displayed in the user preferences. 3.2 The following is an example of a Java completion proposal computer contribution: <p> <pre> <extension point="descent.ui.javaCompletionProposalComputer" id="textual_proposals" name="Text Proposals"> <proposalCategory icon="icons/wordcompletions.png"/> </extension> <extension point="descent.ui.javaCompletionProposalComputer" id="WordCompletionProposalComputer" name="Word Completion Proposal Computer"> <javaCompletionProposalComputer class="descent.internal.ui.text.java.HippieProposalComputer" categoryId="org.eclipse.ui.texteditor.textual_proposals"> <partition type="__java_javadoc"/> </javaCompletionProposalComputer> </extension> </pre> </p> The contributed class must extend <code>descent.ui.text.java.IJavaCompletionProposalComputer</code> see <code>descent.internal.ui.text.java.HippieProposalComputer</code> for an example.
