public abstract VisitContext getWrapped()
public javax.faces.context.FacesContext getFacesContext()
VisitContextReturns the FacesContext for the current request.
getFacesContext in class VisitContextpublic javax.faces.event.PhaseId getPhaseId()
VisitContextReturns the PhaseId, if any that, that this visit is ocurring under
getPhaseId in class VisitContextpublic Set<VisitHint> getHints()
VisitContextReturns hints that influence the behavior of the tree visit.
Interested parties, such as
UIComponent.visitTree() implementations,
may check to see whether a particular hint is present by calling
VisitContext.getHints().contains(), passing in one of the
hints defined by VisitHint.
getHints in class VisitContextpublic Collection<String> getIdsToVisit()
VisitContextReturns the ids of the components to visit.
In the case of a full tree visit, this method returns the ALL_IDS collection. Otherwise, if a partial visit is being performed, returns a modifiable collection containing the client ids of the components that should be visited.

Collection of client ids.public Collection<String> getSubtreeIdsToVisit(javax.faces.component.UIComponent component)
VisitContextGiven a NamingContainer component, returns the client ids of any components underneath the NamingContainer that should be visited.
This method is called by NamingContainer visitTree() implementations to determine whether the NamingContainer contains components to be visited. In the case where no such components exist, the NamingContainer can short-circuit the tree visit and avoid descending into child subtrees.
In addition, iterating components such as UIData may be able to use the returned ids to determine which iterated states (ie. rows) need to be visited. This allows the visit traversal to be contstrained such only those rows that contain visit targets need to be traversed.
