This
Callback class
represents a request for a password. A
CallbackHandler should handle it by displaying the
prompt returned by getPrompt( ) and then allowing
the user the enter a password. When the user has entered the
password, it should pass the entered text to setPassword(
)
. If isEchoOn(
) returns true, then the Handler should
display the password as the user types it.
