EventListener, javax.faces.component.PartialStateHolder, javax.faces.component.StateHolder, javax.faces.component.TransientStateHolder, javax.faces.component.ValueHolder, javax.faces.event.ComponentSystemEventListener, javax.faces.event.FacesListener, javax.faces.event.SystemEventListenerHolder, StyleClassProps

Direct Known Subclasses:

UIPlaceholder

public abstract class AbstractPlaceholder
extends javax.faces.component.UIOutput
implements StyleClassProps

Adds placeholder capability to HTML input and textarea elements. A placeholder typically appears as light gray text within an input or textarea element whenever the element is empty and does not have focus. This provides a hint to the user as to what the input or textarea element is used for, or the type of input that is required.
