Method Summary

Modifier and Type	Method	Description
Baseboard	getBaseboard()	Get the computer system baseboard/motherboard.
Firmware	getFirmware()	Get the computer system firmware/BIOS.
String	getHardwareUUID()	Get the computer system hardware UUID, if available.
String	getManufacturer()	Get the computer system manufacturer.
String	getModel()	Get the computer system model.
String	getSerialNumber()	Get the computer system serial number, if available.

Method Details

getManufacturer

String getManufacturer()

Get the computer system manufacturer.

Returns:

The manufacturer.

getModel

String getModel()

Get the computer system model.

Returns:

The model.

getSerialNumber

String getSerialNumber()

Get the computer system serial number, if available.

Performs a best-effort attempt to retrieve a unique serial number from the computer system. This may originate from the baseboard, BIOS, processor, etc.

This value is provided for information only. Caution should be exercised if using this result to "fingerprint" a system for licensing or other purposes, as the result may change based on program permissions or installation of software packages. Specifically, on Linux and FreeBSD, this requires either root permissions, or installation of the (deprecated) HAL library (lshal command). Linux also attempts to read the dmi/id serial number files in sysfs, which are read-only root by default but may have permissions altered by the user.

Returns:

the System Serial Number, if available, otherwise returns "unknown"

getHardwareUUID

String getHardwareUUID()

Get the computer system hardware UUID, if available.

Performs a best-effort attempt to retrieve the hardware UUID.

Returns:

the Hardware UUID, if available, otherwise returns "unknown"

getFirmware

Firmware getFirmware()

Get the computer system firmware/BIOS.

Returns:

A Firmware object for this system

getBaseboard

Baseboard getBaseboard()

Get the computer system baseboard/motherboard.

Returns:

A Baseboard object for this system
