| * 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 <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> |
