Constructor & Destructor Documentation

NetworkMonitorStub()

ndn::net::NetworkMonitorStub::NetworkMonitorStub ( uint32_t  capabilities )

explicit

Constructor.

Parameters

capabilities

The capabilities reported by getCapabilities()

Definition at line 101 of file network-monitor-stub.cpp.

Member Function Documentation

addInterface()

void ndn::net::NetworkMonitorStub::addInterface

(

shared_ptr< NetworkInterface >

netif

)

Emit the onInterfaceAdded signal and add netif internally.

Parameters

netif

new network interface

Postcondition

getNetworkInterface(netif->getName()) == netif

listNetworkInterfaces() contains netif

Exceptions

std::invalid_argument

a network interface with the same name already exists

Definition at line 119 of file network-monitor-stub.cpp.

emitEnumerationCompleted()

void ndn::net::NetworkMonitorStub::emitEnumerationCompleted

(

)

Emit the onEnumerationCompleted signal.

A real NetworkMonitor starts with an "enumerating" state, during which the initial information about network interfaces is collected from the OS. Upon discovering a network interface, it emits the onInterfaceAdded signal. When the initial enumerating completes, it emits the onEnumerationCompleted signal.

To simulate this procedure on a newly constructed MockNetworkMonitor, the caller should invoke addInterface() once for each network interface that already exists, and then invoke emitEnumerationCompleted().

Definition at line 131 of file network-monitor-stub.cpp.

getCapabilities()

uint32_t ndn::net::NetworkMonitor::getCapabilities ( ) const

inherited

Returns a bitwise OR'ed set of Capability flags supported on the current platform.

Definition at line 72 of file network-monitor.cpp.

getNetworkInterface()

shared_ptr< const NetworkInterface > ndn::net::NetworkMonitor::getNetworkInterface ( const std::string &  ifname ) const

inherited

Returns the NetworkInterface with the given name, or nullptr if it does not exist.

Definition at line 78 of file network-monitor.cpp.

listNetworkInterfaces()

std::vector< shared_ptr< const NetworkInterface > > ndn::net::NetworkMonitor::listNetworkInterfaces ( ) const

inherited

Lists all network interfaces currently available on the system.

Warning

May return incomplete results if called before the onEnumerationCompleted signal has been emitted.

Definition at line 84 of file network-monitor.cpp.

makeNetworkInterface()

shared_ptr< NetworkInterface > ndn::net::NetworkMonitorStub::makeNetworkInterface ( )

static

Create a NetworkInterface instance.

Definition at line 113 of file network-monitor-stub.cpp.

removeInterface()

void ndn::net::NetworkMonitorStub::removeInterface

(

const std::string &

ifname

)

Emit the onInterfaceRemoved signal and remove netif internally.

Parameters

ifname

network interface name

Postcondition

getNetworkInterface(ifname) == nullptr

listNetworkInterfaces() does not contains an interface with specified name

Note

If the specified interface name does not exist, this operation has no effect.

Definition at line 125 of file network-monitor-stub.cpp.

Member Data Documentation

onEnumerationCompleted

signal::Signal<NetworkMonitorImpl>& ndn::net::NetworkMonitor::onEnumerationCompleted

inherited

Fires when the enumeration of all network interfaces on the system is complete.

Definition at line 116 of file network-monitor.hpp.

onInterfaceAdded

signal::Signal<NetworkMonitorImpl, shared_ptr<const NetworkInterface> >& ndn::net::NetworkMonitor::onInterfaceAdded

inherited

Fires whenever a new interface is detected on the system.

Definition at line 119 of file network-monitor.hpp.

onInterfaceRemoved

signal::Signal<NetworkMonitorImpl, shared_ptr<const NetworkInterface> >& ndn::net::NetworkMonitor::onInterfaceRemoved

inherited

Fires whenever an interface disappears from the system.

Note

The NetworkInterface object has already been removed from the list returned by listNetworkInterfaces() when this signal is emitted.

Definition at line 126 of file network-monitor.hpp.

onNetworkStateChanged

signal::Signal<NetworkMonitorImpl>& ndn::net::NetworkMonitor::onNetworkStateChanged

inherited

Deprecated:

Only for backward compatibility
