◆ ProcessRecv()

bool dabc::RepeaterModule::ProcessRecv ( unsigned  port)
virtual

Method called by framework when at least one buffer available in input port.

Can be reimplemented by the user. Method should return true is user want method to be called again for next buffer in input port

Reimplemented from dabc::ModuleAsync.

Definition at line 99 of file MultiplexerModule.cxx.

◆ ProcessSend()

bool dabc::RepeaterModule::ProcessSend ( unsigned  port)
virtual

Method called by framework when at least one buffer can be send to output port.

Can be reimplemented by the user. Method should return true is user want method to be called again for next possibility to send buffer

Reimplemented from dabc::ModuleAsync.
