public enum ElementType
extends Enum<ElementType>

A program element type. The constants of this enumerated type provide a simple classification of the declared elements in a Java program.

These constants are used with the Target meta-annotation type to specify where it is legal to use an annotation type.

Method Detail

values

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

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

valueOf

public static ElementType 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
