Method Detail

getUIClassID

public String getUIClassID()

Returns the UIClassID

Overrides:

getUIClassID in class JTextField

Returns:

the string "PasswordFieldUI"

See Also:

JComponent.setUI(javax.swing.plaf.ComponentUI), JComponent.updateUI()

getEchoChar

public char getEchoChar()

getEchoChar

Returns:

the echo char

setEchoChar

public void setEchoChar(char echo)

setEchoChar

Parameters:

echo - the echo char

echoCharIsSet

public boolean echoCharIsSet()

Returns true if this JPasswordField has a character set for echoing. A character is considered to be set if the echo character is not 0.

Returns:

true if the echo char is set, false otherwise.

copy

public void copy()

Copies the selected text into the clipboard. This operation is not allowed in a password input field.

Overrides:

copy in class JTextComponent

cut

public void cut()

Cuts the selected text and puts it into the clipboard. This operation is not allowed in a password input field.

Overrides:

cut in class JTextComponent

getText

public String getText()

Deprecated.

Returns the text contained in this TextComponent. If the underlying document is null, will give a NullPointerException.

Overrides:

getText in class JTextComponent

Returns:

String

getText

public String getText(int offset,
             int length)
               throws BadLocationException

Deprecated.

Fetches a portion of the text represented by the component. Returns an empty string if length is 0. If the underlying document is null, will give a NullPointerException.

Overrides:

getText in class JTextComponent

Parameters:

offset - TODO

length - TODO

Returns:

String

Throws:

BadLocationException - TODO

getPassword

public char[] getPassword()

Returns the text contained in this TextComponent. If the underlying document is null, will give a NullPointerException. For stronger security, it is recommended that the returned character array be cleared after use by setting each character to zero.

Returns:

char[]

paramString

protected String paramString()

Returns a string representation of this JPasswordField. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be null.

Overrides:

paramString in class JTextComponent

Returns:

String

getAccessibleContext

public AccessibleContext getAccessibleContext()

getAccessibleContext

Specified by:

getAccessibleContext in interface Accessible

Overrides:

getAccessibleContext in class JTextField

Returns:

the AccessibleContext object
