All subclasses of this class:

Should be immutable, e.g. only final private fields in the instances.

Don't need to override hashCode - object refs suffice.

Should be careful with static fields that are not of this type.

Should be final because fieldnames (public static final) could collide.

Method Detail

readResolve

public java.lang.Object readResolve()
                             throws java.io.ObjectStreamException

Replace the deserialized instance with the local static instance to allow correct usage of == operator

Throws:

java.io.ObjectStreamException

getEnumConstants

protected static java.util.List getEnumConstants(java.lang.Class cls)

Return the constants, in the order declared.

Subclasses, e.g. FooEnum with a constant named FOO, should implement:

 public static FooEnum[] getConstants() {
   List temp = FOO.getEnumConstants();
   return (FooEnum[]) temp.toArray(new FooEnum[temp.size()]);
 }
 

Returns:

an array of constants, as defined in the class.
