Package com.diozero.internal.spi

Class BaseNativeDeviceFactory

java.lang.Object

com.diozero.internal.spi.AbstractDeviceFactory

com.diozero.internal.spi.BaseNativeDeviceFactory

All Implemented Interfaces:

AnalogInputDeviceFactoryInterface, AnalogOutputDeviceFactoryInterface, DeviceFactoryInterface, GpioDeviceFactoryInterface, I2CDeviceFactoryInterface, NativeDeviceFactoryInterface, PwmOutputDeviceFactoryInterface, SerialDeviceFactoryInterface, SpiDeviceFactoryInterface, AutoCloseable

Direct Known Subclasses:

DefaultDeviceFactory

public abstract class BaseNativeDeviceFactory
extends AbstractDeviceFactory
implements NativeDeviceFactoryInterface

Helper class for instantiating different devices via the configured provider. To set the provider edit META-INF/services/com.diozero.spi.provider.NativeDeviceFactoryInterface While the ServiceLoader supports multiple service providers, only the first entry in this file is used
