Detailed Description

This class is a singleton that will monitor the network interfaces on a machine and update a list aof clients on any changes to the number or addresses of the interfaces.

A user may override this singleton by creating a derived class and making a static instance of it before any monitor client classes are created. This would typically be done in the users main program.

		BOOL	runMonitorThread = `TRUE`

Member Function Documentation

static PInterfaceMonitor& PInterfaceMonitor::GetInstance ( ) [static]

Return the singleton interface for the network monitor.

BOOL PInterfaceMonitor::Start ( )

Start monitoring network interfaces.

void PInterfaceMonitor::Stop ( )

Stop monitoring network interfaces.

PStringArray PInterfaceMonitor::GetInterfaces	(	BOOL	includeLoopBack = `FALSE`,
		const PIPSocket::Address &	destination = `PIPSocket::GetDefaultIpAny()`
	)

Get an array of all current interface descriptors, possibly including the loopback (127.0.0.1) interface. Note the names are of the form ipname, eg "10.0.1.11%3Com 3C90x Ethernet Adapter" or "192.168.0.10%eth0"

Parameters:

destination

Flag for if loopback is to included in list

BOOL PInterfaceMonitor::IsValidBindingForDestination	(	const PIPSocket::Address &	binding,
		const PIPSocket::Address &	destination
	)

Returns whether destination is reachable through binding or not. The default behaviour returns TRUE unless there is an interface filter installed an the filter does not return 'binding' among it's interfaces.

BOOL PInterfaceMonitor::GetInterfaceInfo	(	const PString &	iface,
		InterfaceEntry &	info
	)

Return information about an active interface given the descriptor string. Note that when searchin the descriptor may be a partial match e.g. "10.0.1.11" or "%eth0" may be used.

Parameters:

info

Interface desciptor name Information on the interface

void PInterfaceMonitor::SetInterfaceFilter ( PInterfaceFilter * filter )

Sets the monitor's interface filter. Note that the monitor instance handles deletion of the filter.
