private static final long	serialVersionUID
private String	prompt
boolean	echoOn
private char[]	inputPassword

Constructors Summary
public PasswordCallback(String prompt, boolean echoOn) Creates a new {@code PasswordCallback} instance. param prompt the message that should be displayed to the user param echoOn determines whether the user input should be echoed super(); setPrompt(prompt); this.echoOn = echoOn;

Methods Summary
public void	clearPassword() Clears the password stored in this {@code PasswordCallback}. if (inputPassword != null) { Arrays.fill(inputPassword, '\u0000"); }
public char[]	getPassword() Returns the password. The security service that needs the password usually calls this method once the {@link CallbackHandler} has finished its work. return the password. A copy of the internal password is created and returned, so subsequent changes to the internal password do not affect the result. if (inputPassword != null) { char[] tmp = new char[inputPassword.length]; System.arraycopy(inputPassword, 0, tmp, 0, tmp.length); return tmp; } return null;
public java.lang.String	getPrompt() Returns the prompt that was specified when creating this {@code PasswordCallback} return the prompt return prompt;
public boolean	isEchoOn() Queries whether this {@code PasswordCallback} expects user input to be echoed, which is specified during the creation of the object. return {@code true} if (and only if) user input should be echoed return echoOn;
public void	setPassword(char[] password) Sets the password. The {@link CallbackHandler} that performs the actual provisioning or input of the password needs to call this method to hand back the password to the security service that requested it. param password the password. A copy of this is stored, so subsequent changes to the input array do not affect the {@code PasswordCallback}. if (password == null) { this.inputPassword = password; } else { inputPassword = new char[password.length]; System.arraycopy(password, 0, inputPassword, 0, inputPassword.length); }
private void	setPrompt(java.lang.String prompt) if (prompt == null || prompt.length() == 0) { throw new IllegalArgumentException(Messages.getString("auth.14")); //$NON-NLS-1$ } this.prompt = prompt;
