Class HardwareIdService

java.lang.Object
io.github.eggy03.ferrumx.windows.service.compounded.HardwareIdService
All Implemented Interfaces:
OptionalCommonServiceInterface<HardwareId>
public class HardwareIdService extends Object implements OptionalCommonServiceInterface<HardwareId>
Service class for fetching the HWID information from a system running Windows.

This class executes the ScriptEnum.HWID PowerShell script and maps the resulting JSON into an Optional HardwareId object.

Usage examples

// Convenience API (creates its own short-lived session)
HardwareIdService service = new HardwareIdService();
Optional<HardwareId> hwid = service.get();

// API with re-usable session (caller manages session lifecycle)
try (PowerShell session = PowerShell.openSession()) {
      HardwareIdService service = new HardwareIdService();
      Optional<HardwareId> hwid = service.get(session);
}

// API with execution timeout (auto-created session is terminated if the timeout is exceeded)
HardwareIdService service = new HardwareIdService();
Optional<HardwareId> hwid = service.get(10);

Execution models and concurrency

This service supports multiple PowerShell execution strategies:

  • jPowerShell-based execution via get() and get(PowerShell):
    These methods rely on jPowerShell sessions. Due to internal global configuration of jPowerShell, the PowerShell sessions launched by it is not safe to use concurrently across multiple threads or executors. Running these methods in parallel may result in runtime exceptions.
  • Isolated PowerShell execution via get(long timeout):
    This method doesn't rely on jPowerShell and instead, launches a standalone PowerShell process per invocation using TerminalUtility. Each call is fully isolated and safe to use in multithreaded and executor-based environments.

For concurrent or executor-based workloads, prefer get(long timeout).
