Opaque Data
Opaque data is a file of data that is passed directly to the business application without any processing by the CPF. For example a business application could convert an input GIF image to a JPEG image, or a web map service could return an PNG image of the requested map.
For business applications that support opaque input data, one file is specified for each request to be processed (e.g. a GIF image). A business application cannot support both opaque and structured input data. But it can support batch job parameters.
For business applications that support opaque result data, one result file is generated (e.g. a GIF image) for each request. A business application cannot support both opaque and structured result data.
