Method Detail

values

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

Returns:

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

valueOf

public static ImageAngle valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Enum<ImageAngle>

getAngle

public java.lang.Integer getAngle()

Retrieves the angle of the picture as stored in image information.

Returns:

Integer indicating the angle.

getAngle

public static ImageAngle getAngle(java.lang.Integer angle)

Retrieves the enum corresponding to the image angle as stored in the picture.

Returns:

ImageAngle indicating the angle. Will return null if angle not found.

getName

public java.lang.String getName()
