java.lang.Objectjavax.swing.text.View
javax.swing.text.PlainView
javax.swing.text.FieldView
javax.swing.text.PasswordView
Implements a View suitable for use in JPasswordField UI implementations. This is basically a field ui that renders its contents as the echo character specified in the associated component (if it can narrow the component to a JPasswordField).
