Class DeviceFactoryHelper


public class DeviceFactoryHelper
extends Object
Helper class for automatically detecting the native device factory that will be used for provisioning I/O devices. Uses the Java ServiceLoader to detect NativeDeviceFactoryInterface implementations that are available on the class-path as defined in META-INF/services/com.diozero.internal.provider.NativeDeviceFactoryInterface. The first entry is used if there are multiple implementations present on the class-path. Alternatively you can specify the class to use via the command line or environment property diozero.devicefactory. The built-in device factory is used if the above logic fails to instantiate a device factory implementation.
