Syntax

class FEndpoint : public FNoncopyable

Remarks

FEndpoint class is the main interface for sending and receiving data with the DirectLink system.

Instances of this class discover themselves (through MessageBus) and can see Sources and Destinations available on each others. This is automatic and works for multiple applications. With that system, one can expose data from an application and consume it from another.

An endpoint can exposes N sources and N Destinations. That being said, a more classic setup is to have an 'exporter' process that only exposes sources, and some 'consumer' process that only have Destinations.

As a convention, 'consumers' have the responsibility to handle the connections management. Exporters have the sole responsibility to exposes their data.

Setup example:

  • Exporter process
  • Source "My First Source"
  • Source "My Second Source"
  • Consumer process
  • Destination "Viewport"

The consumer process can handle the connections between Sources and Destinations with the OpenStream and CloseStream methods.
