Right, something with the doc generation has gone wrong in this case.
Another missing documentation is how interceptors can be added to FHIR producer endpoints, e.g. to add HTTP headers:
Your Camel/Spring context must then define a bean named "authorizationBean" that implements org.openehealth.ipf.platform.camel.ihe.fhir.core.HapiClientInterceptorFactory. The IClientInterceptor created by this factory can be easily used to set e.g. HTTP headers. There are some trivial examples like ca.uhn.fhir.rest.client.interceptor.BearerTokenInterceptor coming with HAPI FHIR. For dynamic header content, for the time being you might need to use a Thread Local variable to make the SAML Token available to this interceptor.
Hope this helps
