public interface Driver
extends Initializable

A simple interface describing an object that can be used as a device driver. It supports only two methods, Initializable.init() to perform some basic steps when the driver is loaded, like opening a serial port for a RS485Server, and close() to perform some clean-up operations when the driver is unloaded, e.g. closing of a serial port.

Method Summary

Modifier and Type	Method and Description
boolean	close() Performs clean-up step when the driver is unloaded.
String	getDriverName() If more than one driver of a certain class is present, but registering is only allowed to a certain driver, we can use this method to distinguish between different instances of the driver.
boolean	isOpen() Queries the initalization status of the driver.
boolean	open() Performs initialization steps when the driver is loaded for the first time.

Methods inherited from interface util.Initializable

init

Method Detail

open

boolean open()
      throws IOException

Performs initialization steps when the driver is loaded for the first time. A driver that communicates with the serial port will open the port in this instance.

Returns:

True if initialization was successful.

Throws:

IOException

isOpen

boolean isOpen()

Queries the initalization status of the driver. If the driver has been successfully initalized this method should return true.

Returns:

True, if a previous initialization was successful

close

boolean close()
       throws IOException

Performs clean-up step when the driver is unloaded. A serial-port driver will probably close the serial port in this method.

Returns:

True if clean-up was successful.

Throws:

IOException

getDriverName

String getDriverName()

If more than one driver of a certain class is present, but registering is only allowed to a certain driver, we can use this method to distinguish between different instances of the driver.
