Method Detail

values

public static QuadrantRotation[] 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 (QuadrantRotation c : QuadrantRotation.values())
    System.out.println(c);

Returns:

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

valueOf

public static QuadrantRotation 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

degrees

public int degrees()

Returns:

the rotation's angle, measured in degrees

radians

public double radians()

Returns:

the rotation's angle, measured in radians

forDegrees

public static QuadrantRotation forDegrees(int degrees)

Retrieve the constant corresponding to a given rotation angle.

Parameters:

degrees - rotation angle, measured in degrees

Returns:

the constant corresponding to the given angle

Throws:

IllegalArgumentException - if the given rotation angle is not a quadrant rotation, that is, one of 0, 90, 180 or 270 degrees.
