int	getNumInterfacesAvailable() Returns the number of available interfaces, i.e., the number of available hardware devices.

Method Detail

getNumInterfacesAvailable

int getNumInterfacesAvailable()

Returns the number of available interfaces, i.e., the number of available hardware devices. If the driver only supports one interface, then 1 will always be returned.

Returns:

number of interfaces

getFirstAvailableInterface

HardwareInterface getFirstAvailableInterface()
                                             throws HardwareInterfaceException

Gets the first available interface.

Returns:

first available interface, or null if no interfaces are found.

Throws:

HardwareInterfaceException

getInterface

HardwareInterface getInterface(int n)
                               throws HardwareInterfaceException

Returns one of the interfaces

Parameters:

n - the number starting from 0

Returns:

the HardwareInterface

Throws:

HardwareInterfaceException - if there is some error
