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 DefaultValue annotation. The type T of the annotated parameter, field or property must either: 
    

  1. Be a primitive type
    2. 

  2. Be Cookie
    3. 

  3. Have a constructor that accepts a single String argument
    4. 

  4. Have a static method named valueOf or fromString that accepts a single String argument (see, for example, Integer.valueOf(String))
    5. 

  5. Have a registered implementation of ParamConverterProvider JAX-RS extension SPI that returns a ParamConverter instance capable of a "from string" conversion for the type.
    6. 

  6. Be List<T>, Set<T> or SortedSet<T>, where T satisfies 2, 3, 4 or 5 above. The resulting collection is read-only.
    7. 




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.
