/**
* Binds the value(s) of a HTTP query parameter to a resource method parameter,
* resource class field, or resource class bean property.
* Values are URL decoded unless this is disabled using the {@link Encoded}
* annotation. A default value can be specified using the {@link DefaultValue}
* annotation.
*
* The type <code>T</code> of the annotated parameter, field or property must
* either:
* <ol>
* <li>Be a primitive type</li>
* <li>Have a constructor that accepts a single <code>String</code> argument</li>
* <li>Have a static method named <code>valueOf</code> or <code>fromString</code>
* that accepts a single
* <code>String</code> argument (see, for example, {@link Integer#valueOf(String)})</li>
* <li>Be <code>List<T></code>, <code>Set<T></code> or
* <code>SortedSet<T></code>, where <code>T</code> satisfies 2 or 3 above.
* The resulting collection is read-only.</li>
* </ol>
*
* <p>If the type is not one of those listed in 4 above then the first value
* (lexically) of the parameter is used.</p>
*
* <p>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.</p>
