questions of Linkage between NS and source

["yanglihai" <lhyang@cti.com.cn>]

hello all,

   recently,I am researching linkage between NS and it's c++ source.

     but, Confused by two questions below,I desire for an answer.

 

    1)how to create class TclObject and class TclClass by global procedure new{}

    e.g.(in packet.cc)

    /* manages active packet header types */
    class PacketHeaderManager : public TclObject {
    public:
     PacketHeaderManager() {
      bind("hdrlen_", &Packet::hdrlen_);
         }
    };

 

    static class PacketHeaderManagerClass : public TclClass {
    public:
     PacketHeaderManagerClass() : TclClass("PacketHeaderManager") {}
     TclObject* create(int, const char*const*) {
      return (new PacketHeaderManager);
         }
    } class_packethdr_mgr;

 

  2)when creating a static unicast topology ,whether or not NS generates a table

    that saved all target_ object address,for running target_->recv(p,h).

    because I find that class object attached target_ address is generated,

    as using xemacs+gdb to trace it.

    e.g.

    class xxx {this =0x...,packet=0x...,h=....}

    {

        name_=...

        target_=0x...,

        ...

    }

    any help is appreciated.

   

    Best regards
