Package javax. faces. component. visit
APIs for traversing a user interface component view.
See: Description
-
Interface Summary Interface Description VisitCallback A simple callback interface that enables taking action on a specific UIComponent (either facet or child) during a component tree visit.
-
Class Summary Class Description VisitContext A context object that is used to hold state relating to performing a component tree visit.
VisitContextFactory Provide for separation of interface and implementation for the
VisitContextcontract.VisitContextWrapper Provides a simple implementation of
VisitContextthat can be subclassed by developers wishing to provide specialized behavior to an existingVisitContextinstance. -
Enum Summary Enum Description VisitHint An enum that specifies hints that impact the behavior of a component tree visit.
VisitResult An enum that specifies the possible results of a call to
VisitCallback.visit(javax.faces.component.visit.VisitContext, javax.faces.component.UIComponent).
Package javax.faces.component.visit Description
APIs for traversing a user interface component view.
The following example visits all nodes in the view.
- UIViewRoot root = facesContext.getViewRoot();
- root.visitTree(VisitContext.createVisitContext(context),
- new VisitCallback() {
- public VisitResult visit(VisitContext context,
- UIComponent target) {
- // take some action on target
- return VisitResult.ACCEPT;
- }
- });
The following example visits two subtrees within the component view.
- Set<String> toVisit = getSet("form1:optionsPanel", "form2:detailPanel");
- UIViewRoot root = facesContext.getViewRoot();
- root.visitTree(VisitContext.createVisitContext(context, toVisit, null),
- new VisitCallback() {
- public VisitResult visit(VisitContext context,
- UIComponent target) {
- // take some action on target
- return VisitResult.ACCEPT;
- }
- });
Note that every child node of those two subtrees is visited.
