Class Enum

java.lang.Object
oracle.ide.util.Enum

All Implemented Interfaces:

java.lang.Comparable

Direct Known Subclasses:

ContentType

public abstract class Enum

extends java.lang.Object

implements java.lang.Comparable

Enum superclass to assist with the declaration of type-safe enumerations following the enums-as-objects pattern, pending enumerated types in the "Tiger" release of Java (J2SE 1.5).

Example:

public final class Animal extends Enum
{
public static final Animal CAT = new Animal( "CAT" );
public static final Animal DOG = new Animal( "DOG" );
public static final Animal MAN = new Animal( "MAN" );

private static final Animal[] PRIVATE_VALUES = { CAT, DOG, MAN };
private static int _nextOrdinal = 0;

private Animal( String name ) {
super( name, _nextOrdinal++ );
}

public static final Animal valueOf( String name ) {
return (Animal)Enum.valueOf( PRIVATE_VALUES, name );
}

public static final Animal[] values() {
return (Animal[])PRIVATE_VALUES.clone();
}
}
