Method Details

values

public static RotationAngle[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static RotationAngle valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

getInstance

public static RotationAngle getInstance(String s)
                                 throws InvalidArgumentException

Returns a RotationAngle corresponding to a string.

Parameters:

s - a String from which the most-like plane will be interpreted. Can be:

• "+90",
• "180", or
• "-90".

Interpretation of the String is case-insensitive.

Returns:

a RotationAngle corresponding to a String.

Throws:

InvalidArgumentException - if the String is invalid.

getPreferredRotationAngle

public static RotationAngle getPreferredRotationAngle(Preferences prefs)

Gets the preferred rotation angle from the Preferences.

Parameters:

prefs - the Preferences from which to get the rotation angle.

Returns:

the preferred RotationAngle.

savePreferredRotationAngle

public static void savePreferredRotationAngle(Preferences prefs,
 RotationAngle rotationAngle)

Saves the supplied rotation angle to the Preferences as the preferred RotationAngle.

Parameters:

prefs - the Preferences in which to save the rotation angle.

rotationAngle - the RotationAngle to save as the preferred one.

toString

public String toString()

Returns a java.lang.String describing this RotationAngle.

Overrides:

toString in class Enum<RotationAngle>

Returns:

a java.lang.String describing this RotationAngle.
