/**
 * 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 {@code 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 {@code valueOf} or {@code fromString} that accepts a single
 *       String argument (see, for example, {@link Integer#valueOf(String)})
 *   
Have a registered implementation of {@link javax.ws.rs.ext.ParamConverterProvider} JAX-RS
 *       extension SPI that returns a {@link javax.ws.rs.ext.ParamConverter} instance capable of a
 *       "from string" conversion for the type.
 *   
Be {@code List}, {@code Set} or {@code SortedSet}, where {@code T} satisfies 2, 3,
 *       4 or 5 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.
