Detailed Description

Abstract Channel Base Class.


A channel is a logical path over which information flows. The path can be as simple as a short piece of wire, or as complicated as space-time.

Subclasses must use Simulator::ScheduleWithContext to correctly update event contexts when scheduling an event from one node to another one.

Config Paths

ns3::Channel is accessible through the following paths with Config::Set and Config::Connect:

Attributes

No TraceSources are defined for this type.
Size of this type is 32 bytes (on a 64-bit architecture).

Definition at line 43 of file channel.h.

Constructor & Destructor Documentation

◆ Channel()

ns3::Channel::Channel ( )

Definition at line 46 of file channel.cc.

References ns3::ChannelList::Add(), m_id, and NS_LOG_FUNCTION.

◆ ~Channel()

ns3::Channel::~Channel ( )
virtual

Definition at line 53 of file channel.cc.

References NS_LOG_FUNCTION.

Member Function Documentation

◆ GetDevice()

virtual Ptr<NetDevice> ns3::Channel::GetDevice ( std::size_t  i) const
pure virtual
Parameters
iindex of NetDevice to retrieve
Returns
one of the NetDevices connected to this channel.

This method must be implemented by subclasses.

Implemented in ns3::CsmaChannel, ns3::MultiModelSpectrumChannel, ns3::PointToPointChannel, ns3::SimpleChannel, ns3::UanChannel, ns3::WimaxChannel, ns3::SingleModelSpectrumChannel, ns3::YansWifiChannel, ns3::ErrorChannel, and ns3::BridgeChannel.

◆ GetId()

uint32_t ns3::Channel::GetId ( void  ) const
Returns
the unique id of this channel

This unique id happens to be also the index of the Channel into the ChannelList.

Definition at line 59 of file channel.cc.

References m_id, and NS_LOG_FUNCTION.

◆ GetNDevices()

virtual std::size_t ns3::Channel::GetNDevices ( void  ) const
pure virtual

◆ GetTypeId()

TypeId ns3::Channel::GetTypeId ( void  )
static

Get the type ID.

Returns
the object TypeId

Definition at line 33 of file channel.cc.

References ns3::TypeId::ATTR_GET, m_id, ns3::MakeUintegerAccessor(), and ns3::TypeId::SetParent().

Member Data Documentation

◆ m_id

uint32_t ns3::Channel::m_id
private

Channel id for this channel.

Definition at line 78 of file channel.h.
