Method Detail

instance

public static HardwareInterfaceFactoryInterface instance()

Returns:

singleton instance

getNumInterfacesAvailable

public int getNumInterfacesAvailable()

Description copied from interface: HardwareInterfaceFactoryInterface

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.

Specified by:

getNumInterfacesAvailable in interface HardwareInterfaceFactoryInterface

Returns:

number of interfaces

getFirstAvailableInterface

public HardwareInterface getFirstAvailableInterface()
                                             throws HardwareInterfaceException

Description copied from interface: HardwareInterfaceFactoryInterface

Gets the first available interface.

Specified by:

getFirstAvailableInterface in interface HardwareInterfaceFactoryInterface

Returns:

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

Throws:

HardwareInterfaceException

getInterface

public HardwareInterface getInterface(int n)
                               throws HardwareInterfaceException

Description copied from interface: HardwareInterfaceFactoryInterface

Returns one of the interfaces

Specified by:

getInterface in interface HardwareInterfaceFactoryInterface

Parameters:

n - the number starting from 0

Returns:

the HardwareInterface

Throws:

HardwareInterfaceException - if there is some error

onAdd

public void onAdd()

Specified by:

onAdd in interface de.thesycon.usbio.PnPNotifyInterface

onRemove

public void onRemove()

Specified by:
