16.4. Context Mapper Implementations Available Out-of-the-Box

When processing an incoming SOAPMessage, the SOAPContextMapper takes the MIME (in most cases, HTTP) headers from a SOAP envelope and maps them into the SwitchYard Context as Scope.IN properties with the SOAPComposition.SOAP_MESSAGE_MIME_HEADER label, and takes the SOAP header elements from the soap envelope and maps them into the SwitchYard Context as Scope.EXCHANGE properties with the SOAPComposition.SOAP_MESSAGE_HEADER label. When processing an outgoing SOAPMessage, it takes the SwitchYard Scope.OUT Context properties and maps them into mime (in most cases, HTTP) headers, and takes the SwitchYard Scope.EXCHANGE Context properties and maps them into the SOAP envelope as soap header elements.

You can map these properties with a namespace to the soap header.

<binding.soap>
    <contextMapper includes=".*" soapHeadersType="VALUE"/>
</binding.soap>

<binding.soap>
    <contextMapper includes=".*" soapHeadersType="VALUE"/>
</binding.soap>

When processing an incoming CamelMessage, the CamelContextMapper takes the CamelMessage headers and maps them into the SwitchYard Context as Scope.IN properties with the CamelComposition.CAMEL_MESSAGE_HEADER label, and takes the Camel Exchange properties and maps them into the SwitchYardContext as Scope.EXCHANGE properties with the CamelComposition.CAMEL_EXCHANGE_PROPERTY label. When processing an outgoing CamelMessage, it takes the SwitchYard Scope.OUT Context properties and maps them into the CamelMessage as headers, and takes the SwitchYard Scope.EXCHANGE Context properties and maps them into the Camel Exchange as properties.

When processing an incoming HTTP request, the HttpContextMapper takes the incoming request headers and maps them into the SwitchYard Context as Scope.IN with the HttpComposition.HTTTP_HEADER label. When processing an outgoing HTTP response, it takes the SwitchYard Scope.OUT Context properties and maps them into the response headers.

When processing an incoming HTTP request, the RESTEasyContextMapper takes the incoming request headers and maps them into the SwitchYard Context as Scope.IN with the RESTEasyComposition.HTTP_HEADER label. When processing an outgoing HTTP response, it takes the SwitchYard Scope.OUT Context properties and maps them into the response headers.

When processing an incoming IndexedRecord, the IndexedRecordContextMapper takes the record name and record short description and maps them into the SwitchYardContext as Scope.EXCHANGE properties with the JCAComposition.JCA_MESSAGE_PROPERTY label. When processing an outgoing IndexedRecord, it looks for those properties specifically in the SwitchYard.EXCHANGE Context properties by key and sets them on the IndexedRecord.

When processing an incoming MappedRecord, the MappedRecordContextMapper takes the record name and record short description and maps them into the SwitchYardContext as Scope.EXCHANGE properties with the JCAComposition.JCA_MESSAGE_PROPERTY label. When processing an outgoing MappedRecord, it looks for those properties specifically in the SwitchYard.EXCHANGE Context properties by key and sets them on the MappedRecord.

When processing an incoming (JMS) Message, the JMSContextMapper takes the Message properties and maps them into the SwitchYardContext as Scope.EXCHANGE properties with the JCAComposition.JCA_MESSAGE_PROPERTY label. When processing an outgoing (JMS) Message, it takes the SwitchYard.EXCHANGE Context properties and maps them into the Message as Object properties.
