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.

Port Descriptions

Kind	Name	Type	Description
sync input	dataIn	Svc.ComDataWithContext	Receiving Fw::Buffer with context buffer
output	dataReturnOut	Svc.ComDataWithContext	Returning ownership of buffer received on dataIn
output	allPacketsOut	Fw.BufferSend	Pass-through port for sending all packets received on dataIn
sync input	allPacketsReturnIn	Fw.BufferSend	Receiving back ownership of buffer sent on allPacketsOut
