public interface GPIBDriver

An abstract GPIB driver interface that any driver implementation should implement.

Method Summary

void	clearDevice(int _descriptor) Clears a specific device
be.ac.ulb.gpib.GPIBDevice	getDevice(int address) returns a GPIB device using its GPIB address.
void	initialize() initialize() will be called by the GPIBDeviceIdentifier's static initializer.
int	openDevice(int _address) Opens a GPIB device present at specific address.
java.lang.String	sendCommand(java.lang.String _message, int _address) sends a valid GPIB command to the device.
void	writeCommand(java.lang.String _message, int _address) sends a valid GPIB command to the device.

Method Detail

initialize

public void initialize()

initialize() will be called by the GPIBDeviceIdentifier's static initializer. The responsibility of this method is: 1) Ensure that that the hardware is present. 2) Load any required native libraries. 3) Register the port names with the CommPortIdentifier.

getDevice

public be.ac.ulb.gpib.GPIBDevice getDevice(int address)

returns a GPIB device using its GPIB address. See IEEE488 and IEEE488.2 specifications

Parameters:

address - the GPIB address (from 0 to 31)

sendCommand

public java.lang.String sendCommand(java.lang.String _message,
                                    int _address)
                             throws java.io.IOException

sends a valid GPIB command to the device.

Returns:

a String representing device's answer to the command

java.io.IOException

writeCommand

public void writeCommand(java.lang.String _message,
                         int _address)
                  throws java.io.IOException

sends a valid GPIB command to the device.

java.io.IOException

clearDevice

public void clearDevice(int _descriptor)
                 throws java.io.IOException

Clears a specific device

Parameters:

_descriptor - an unique integer referecing the device internally. It is not necessarely the GPIB address.

java.io.IOException

openDevice

public int openDevice(int _address)
               throws java.io.IOException

Opens a GPIB device present at specific address.

Parameters:

_address - the GPIB address of the device.

java.io.IOException
