This extension point is used to extend Java UI views with filters. a fully qualified identifier of the target extension point an optional identifier of the extension instance an optional name of the extension instance a unique id that will be used to identify this filter. a unique name that allows to identify this filter in the UI. This attribute should be a translated string. Though this attribute is not required for pattern filters (i.e. those using the <samp>pattern</samp> attribute) we suggest to provide a name anyway, otherwise the pattern string itself would be used to represent the filter in the UI. a short description for this filter. This attribute should be a translated string. the id of the target where this filter is contributed. If this attribute is missing, then the filter will be contributed to all views which use the <samp>descent.ui.actions.customFiltersActionGroup</samp>. This replaces the deprecated attributed "viewId". the filter will be enabled if this attribute is present and its value is "true". Most likely the user will be able to override this setting in the UI. elements whose name matches this pattern will be hidden. This attribute is here for backward compatibility and should no longer be used. All views that allow to plug-in a filter also allow to add pattern filters directly via UI. the name of the class used to filter the view. The class must extend <samp>org.eclipse.jface.viewers.ViewerFilter</samp>. If this attribute is here then the pattern attribute must not provided. The following is an example of Java element filter definition. It filters out inner classes and is initially selected. <p> <pre> <extension point="descent.ui.javaElementFilters"> <filter id="descent.ui.PackageExplorer.LibraryFilter" name="%HideReferencedLibraries.label" description="%HideReferencedLibraries.description" targetId="descent.ui.PackageExplorer" class="descent.internal.ui.filters.LibraryFilter" enabled="false"> </filter> </extension> </pre> </p> Copyright (c) 2001, 2004 IBM Corporation and others.<br> All rights reserved.
