| <div class="block">Defines a contract for a delegate responsible for converting between a <code>String</code> form of a message parameter |
| value and the corresponding custom Java type <code>T</code>. |
| |
| Conversion of message parameter values injected via <a href="../../../../jakarta/ws/rs/PathParam.html" title="annotation in jakarta.ws.rs"><code>@PathParam</code></a>, |
| <a href="../../../../jakarta/ws/rs/QueryParam.html" title="annotation in jakarta.ws.rs"><code>@QueryParam</code></a>, <a href="../../../../jakarta/ws/rs/MatrixParam.html" title="annotation in jakarta.ws.rs"><code>@MatrixParam</code></a>, |
| <a href="../../../../jakarta/ws/rs/FormParam.html" title="annotation in jakarta.ws.rs"><code>@FormParam</code></a>, <a href="../../../../jakarta/ws/rs/CookieParam.html" title="annotation in jakarta.ws.rs"><code>@CookieParam</code></a> and |
| <a href="../../../../jakarta/ws/rs/HeaderParam.html" title="annotation in jakarta.ws.rs"><code>@HeaderParam</code></a> is supported. |
| JAX-RS implementations MUST support the <code>ParamConverter</code> mechanism for all Java types. If a |
| <code>ParamConverter</code> is available for a type, it MUST be preferred over all other conversion strategies mentioned |
| in section 3.2 (i.e. single <code>String</code> argument constructor, static <code>valueOf</code> or <code>fromString</code> |
| methods, etc.). |
| <p> |
| By default, when used for injection of parameter values, a selected <code>ParamConverter</code> instance MUST be used |
| eagerly by a JAX-RS runtime to convert any <a href="../../../../jakarta/ws/rs/DefaultValue.html" title="annotation in jakarta.ws.rs"><code>default value</code></a> in the resource or provider model, that |
| is during the application deployment, before any value – default or otherwise – is actually required. |
| This conversion strategy ensures that any errors in the default values are reported as early as possible. This |
| default behavior may be overridden by annotating the <code>ParamConverter</code> implementation class with a <a href="../../../../jakarta/ws/rs/ext/ParamConverter.Lazy.html" title="annotation in jakarta.ws.rs.ext"><code>@Lazy</code></a> annotation. In such case any default value conversion delegated to the <code>@Lazy</code>-annotated converter |
| will be deferred to a latest possible moment (i.e. until the injection of such default value is required). |
| </p> |
| <p> |
| NOTE: A service implementing this contract is not recognized as a registrable JAX-RS extension provider. Instead, a |
| <a href="../../../../jakarta/ws/rs/ext/ParamConverterProvider.html" title="interface in jakarta.ws.rs.ext"><code>ParamConverterProvider</code></a> instance responsible for providing <code>ParamConverter</code> instances has to be |
| registered as one of the JAX-RS extension providers. |
