Detailed Description

LTE RLC Transparent Mode (TM), see 3GPP TS 36.322.

Please note that, as in TM it is not possible to add any header, the delay measurements gathered from the trace source "RxPDU" of LteRlc are invalid (they will be always 0)

Member Function Documentation

◆ DoDispose()

void ns3::LteRlcTm::DoDispose ( void  )
overridevirtual

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.

Reimplemented from ns3::Object.
