<div class="block">Binds the value(s) of a HTTP header to a resource method parameter,
resource class field, or resource class bean property. A default value
can be specified using the <a href="../../../javax/ws/rs/DefaultValue.html" title="annotation in javax.ws.rs"><code>DefaultValue</code></a> 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, <code>Integer.valueOf(String)</code>)</li>
<li>Have a registered implementation of <a href="../../../javax/ws/rs/ext/ParamConverterProvider.html" title="interface in javax.ws.rs.ext"><code>ParamConverterProvider</code></a>
that returns a <a href="../../../javax/ws/rs/ext/ParamConverter.html" title="interface in javax.ws.rs.ext"><code>ParamConverter</code></a>
instance capable of a "from string" conversion for the type.</li>
<li>Be <code>List&lt;T&gt;</code>, <code>Set&lt;T&gt;</code> or
<code>SortedSet&lt;T&gt;</code>, where <code>T</code> satisfies 2, 3 or 4 above.
The resulting collection is read-only.</li>
</ol>
<p>If the type is not one of the collection types listed in 5 above and the
header parameter is represented by multiple values 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></div>
