/**
* Binds the value(s) of a URI matrix 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 T of the annotated parameter, field or property 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.
*
* 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.
