Svc::PassThroughRouter
The Svc::PassThroughRouter component is a direct pass through router for single custom route use cases.
The Svc::PassThroughRouter component receives F´ packets (as Fw::Buffer objects) and passes them through to other components through synchronous port calls. The input port of type Svc.ComDataWithContext passes this Fw.Buffer object along with optional context data which is typically used for routing. The Svc::PassThroughRouter is intended to be used in cases where there is only a single route. The Svc::PassThroughRouter ignores the received context data and passes the Fw.Buffer through on the allPacketsOut port.
All buffers sent by Svc::PassThroughRouter on the allPacketsOut port are expected to be returned through the allPacketsReturnIn port. To satisfy the dataReturnOut port interface, the default context value is used when returning the buffer.
