Detailed Description

Interface for those who want to produce body content for others. BodyProducer is expected to create the BodyPipe. One pipe cannot have more than one producer.

◆ Start()

void AsyncJob::Start ( const Pointer & job )

staticinherited

Promises to start the configured job (eventually). The job is deemed to be running asynchronously beyond this point, so the caller should only access the job object via AsyncCalls rather than directly.

swanSong() is only called for jobs for which this method has returned successfully (i.e. without throwing).
