A KeySequence is defined as a list of zero or more KeyStrokes, with the stipulation that all KeyStroke objects must be complete, save for the last one, whose completeness is optional. A KeySequence is said to be complete if all of its KeyStroke objects are complete.

All KeySequence objects have a formal string representation available via the toString() method. There are a number of methods to get instances of KeySequence objects, including one which can parse this formal string representation.

All KeySequence objects, via the format() method, provide a version of their formal string representation translated by platform and locale, suitable for display to a user.

KeySequence objects are immutable. Clients are not permitted to extend this class.

Since:
3.0

getInstance

public static 
KeySequence getInstance()
Deprecated. 
Gets an instance of KeySequence.

Returns:

KeySequence getInstance(
KeySequence keySequence,
                                      
KeyStroke keyStroke)
Deprecated. 
Gets an instance of KeySequence given a key sequence and a key stroke.

Parameters:
keySequence - a key sequence. Must not be null.
keyStroke - a key stroke. Must not be null.
Returns:
a key sequence that is equal to the given key sequence with the given key stroke appended to the end. Guaranteed not to be null.

getInstance

public static 
KeySequence getInstance(
KeyStroke keyStroke)
Deprecated. 
Gets an instance of KeySequence given a single key stroke.

Parameters:
keyStroke - a single key stroke. Must not be null.
Returns:
a key sequence. Guaranteed not to be null.

getInstance

public static 
KeySequence getInstance(
KeyStroke[] keyStrokes)
Deprecated. 
Gets an instance of KeySequence given an array of key strokes.

Parameters:
keyStrokes - the array of key strokes. This array may be empty, but it must not be null. This array must not contain null elements.
Returns:
a key sequence. Guaranteed not to be null.

getInstance

public static 
KeySequence getInstance(
List keyStrokes)
Deprecated. 
Gets an instance of KeySequence given a list of key strokes.

Parameters:
keyStrokes - the list of key strokes. This list may be empty, but it must not be null. If this list is not empty, it must only contain instances of KeyStroke.
Returns:
a key sequence. Guaranteed not to be null.

getInstance

public static final 
KeySequence getInstance(
KeySequence newKeySequence)
Deprecated. 
Gets an instance of KeySequence given a new-style key sequence.

Parameters:
newKeySequence - The new-style key sequence to convert into a legacy key sequence; must not be null.
Returns:
a key sequence; never null.
