/**
* 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 {@link DefaultValue}
* annotation.
*
* The type {@code T} of the annotated parameter, field or property must either:
*
*
* - Be a primitive type
*
- Have a constructor that accepts a single {@code String} argument
*
- Have a static method named {@code valueOf} or {@code fromString} that accepts a single
* {@code String} argument (see, for example, {@link Integer#valueOf(String)})
*
- Have a registered implementation of {@link javax.ws.rs.ext.ParamConverterProvider} JAX-RS
* extension SPI that returns a {@link javax.ws.rs.ext.ParamConverter} instance capable of a
* "from string" conversion for the type.
*
- Be {@code List
}, {@code Set} or {@code SortedSet}, where {@code T} satisfies 2, 3
* or 4 above. The resulting collection is read-only.
*
*
* 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.
*
*
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.
