/**
 * Binds the value of a HTTP cookie to a resource method parameter, 
 * resource class field, or resource class bean property.
 * A default value can be specified using the {@link DefaultValue}
 * annotation.
 * 
 * The type T of the annotated parameter, field or property must 
 * either:
 * 
 * Be a primitive type
 * Be {@link javax.ws.rs.core.Cookie}
 * Have a constructor that accepts a single String argument
 * Have a static method named valueOf or fromString
 * that accepts a single 
 * String argument (see, for example, {@link Integer#valueOf(String)})
 * 
Be List<T>, Set<T> or 
 * SortedSet<T>, where T satisfies 2, 3 or 4 above.
 * The resulting collection is read-only.
 * 
 *
 * Because injection occurs at object creation time, use of this annotation 
 * on resource class fields and bean properties is only supported for the 
 * default per-request resource class lifecycle. Resource classes using 
 * other lifecycles should only use this annotation on resource method
 * parameters.
 *
 * @see DefaultValue
 * @see javax.ws.rs.core.Cookie
