networkhotplug
4 min
The networkhotplug object can be used to generate events when a network interface becomes available or unavailable. A networkhotplugevent will be generated, indicating the interface and whether it was attached or detached.
Reconfiguring a network interface may cause it to detach and attach again. A DHCP address renewal may cause an event, even if the IP address hasn't changed.
networkhotplug IDL
interface NetworkHotplugEvent {
attribute String type;
attribute bool attached; // 1 -> attached, 0 -> detached
attribute String interfaceName;
};
callback NetworkHotplugEventCallback = void (NetworkHotplugEvent event);
interface NetworkHotplug {
void addEventListener(String type, NetworkHotplugEventCallback callback);
void removeEventListener(String type, NetworkHotplugEventCallback callback);
}; Event Creation
To create a networkhotplug event, load the @brightsign/networkhotplug module using the Node.js® require() method:
let networkhotplugClass = require("@brightsign/networkhotplug");
let networkhotplug = new networkhotplugClass();NetworkHotPlug
Use this interface to configure a networkhotplug event.
- networkhotplugevent: This event is raised when the hotplug status changes. Use the addEventListener() method to listen for this event, or the removeEventListener() method to remove an event listener.
NetworkHotPlugEvent Properties
- type string: Add or remove an event listener when this type of event occurs.
- attached bool: Can be true or false (1 is attached, 0 is detached)
- interfaceName string: Returns the interface name (for example, "eth0")
Example
let networkhotplugClass = require("@brightsign/networkhotplug");
let networkhotplug = new networkhotplugClass();
networkhotplug.addEventListener("networkhotplugevent", onNetworkHotplugEvent);
function onNetworkHotplugEvent(data) {
if (data.attached)
{ // connected on 'data.interfaceName' }
}
