/**
* Binds the value(s) of a form parameter contained within a request entity body
* to a resource method parameter. Values are URL decoded unless this is
* disabled using the {@link Encoded} annotation. A default value can be
* specified using the {@link DefaultValue} annotation.
* If the request entity body is absent or is an unsupported media type, the
* default value is used.
*
* The type T
of the annotated parameter must either:
*
* - Be a primitive type
* - 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 or 3 above.
* The resulting collection is read-only.
*
*
* If the type is not one of those listed in 4 above then the first value
* (lexically) of the parameter is used.
*
* Note that, whilst the annotation target permits use on fields and methods,
* this annotation is only required to be supported on resource method
* parameters.
