Field Detail

degrees

public final int degrees

The value of degrees specific for this screen rotation.

systemConstant

public final int systemConstant

The flag provided by Surface for this screen rotation.

Method Detail

values

public static Screen.ScreenRotation[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Screen.ScreenRotation c : Screen.ScreenRotation.values())
    System.out.println(c);

Returns:

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

valueOf

public static Screen.ScreenRotation valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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 type has no constant with the specified name

NullPointerException - if the argument is null

resolve

public static Screen.ScreenRotation resolve(int systemConstant)

Resolves an instance of ScreenRotation according to the given systemConstant from the current set of ScreenRotation values.

Parameters:

systemConstant - The id (systemConstant) of the desired screen rotation to resolve.

Returns:

Resolved screen rotation instance or UNKNOWN if there is no screen rotation with the requested constant.
