Class SystemInfo

java.lang.Object

oshi.nativefree.SystemInfo

All Implemented Interfaces:

SystemInfoProvider

public class SystemInfo
extends Object
implements SystemInfoProvider

Native-free SystemInfoProvider for Linux. Uses only procfs, sysfs, and standard Java APIs — no JNA, no FFM, no --enable-native-access required.

This provider is registered at priority 0 (lowest) and is only selected when no higher-priority provider (JNA or FFM) is available on the classpath.

Constructor Details

SystemInfo

public SystemInfo()

Creates a new native-free Linux SystemInfo instance.

Method Details

getOperatingSystem

public OperatingSystem getOperatingSystem()

Description copied from interface: SystemInfoProvider

Creates a new instance of the appropriate platform-specific OperatingSystem.

Specified by:

getOperatingSystem in interface SystemInfoProvider

Returns:

A new instance of OperatingSystem.

getHardware

public HardwareAbstractionLayer getHardware()

Description copied from interface: SystemInfoProvider

Creates a new instance of the appropriate platform-specific HardwareAbstractionLayer.

Specified by:

getHardware in interface SystemInfoProvider

Returns:

A new instance of HardwareAbstractionLayer.

getPriority

public int getPriority()

Description copied from interface: SystemInfoProvider

Returns the priority of this provider. Higher values indicate higher priority. When multiple providers are available, the one with the highest priority is selected.

Priority 0 is reserved for a potential future no-native-access fallback. The JNA-based provider (oshi-core) returns 10. The FFM-based provider (oshi-core-ffm) returns 20 (preferred when available).

Specified by:

getPriority in interface SystemInfoProvider

Returns:

the priority of this provider

isAvailable

public boolean isAvailable()

Description copied from interface: SystemInfoProvider

Returns whether this provider is available in the current runtime environment.

A provider may be unavailable if the current platform is not supported or if required runtime features (such as the FFM API on JDK 25+) are not present.

Specified by:

isAvailable in interface SystemInfoProvider

Returns:

true if this provider can be used in the current environment
