Package jdk.dio

Provides interfaces and classes for device I/O access and control.

See: Description

Interface Summary

Interface	Description
AsyncErrorHandler<P extends Device<? super P>>	The AsyncErrorHandler interface defines methods for getting notified of errors of asynchronous I/O operations.
BufferAccess<B extends java.nio.Buffer>	The BufferAccess interface provides methods for getting access to the device (or the driver thereof) I/O buffers, if any.
Device<P extends Device<? super P>>	The Device interface represents devices in the system.
DeviceConfig<P extends Device<? super P>>	The DeviceConfig class is a tagging interface for all device configuration classes.
DeviceConfig.HardwareAddressing	The HardwareAddressing interface defines an abstraction of an hardware addressing information common on different platforms.
DeviceDescriptor<P extends Device<? super P>>	The DeviceDescriptor interface encapsulates the identifying and descriptive information of a device as well as its registered configuration (hardware addressing parameters, and static and dynamic configuration parameters).
DeviceEventListener	The DeviceEventListener interface is a tagging interface that all event listeners must implement.
InputRoundListener<P extends Device<? super P>,B extends java.nio.Buffer>	The InputRoundListener interface defines methods for getting notified of the completion of an input round.
OutputRoundListener<P extends Device<? super P>,B extends java.nio.Buffer>	The OutputRoundListener interface defines methods for getting notified of the completion of an output round.
RegistrationListener<P extends Device<? super P>>	The RegistrationListener interface defines methods for getting notified of the registration and unregistration of devices.
Transactional	The Transactional interface provides methods for demarcating a communication transaction.

Class Summary

Class	Description
DeviceEvent<P extends Device<? super P>>	The DeviceEvent class encapsulates events fired by or on behalf of a device.
DeviceManager	The DeviceManager class provides methods for opening and registering devices that can then be handled as Device instances.
DeviceMgmtPermission	The DeviceMgmtPermission class defines permissions for registering and unregistering devices as well as opening devices using their registered configurations.
DevicePermission	The DevicePermission abstract class is the superclass of all device permissions.
RegistrationEvent<P extends Device<? super P>>	The RegistrationEvent class encapsulates device registration and unregistration conditions.
RoundCompletionEvent<P extends Device<? super P>,B extends java.nio.Buffer>	The RoundCompletionEvent class encapsulates the completion condition of a round of I/O operation.

Exception Summary

Exception	Description
ClosedDeviceException	Thrown by an instance of Device to indicate that an operation is attempted on a device which is closed.
DeviceAlreadyExistsException	Thrown by the DeviceManager to indicate that a device is already registered for the specified ID.
DeviceException	Thrown to indicate that a general exception occurred on a device operation.
DeviceNotFoundException	Thrown to indicate that there is no device matching the provided device numerical ID, name or properties.
InvalidDeviceConfigException	Thrown to indicate that the provided device configuration is invalid/is not supported.
UnavailableDeviceException	Thrown by the DeviceManager to indicate that a device cannot be open because it is already open or that a device cannot be acquired for exclusive access.
UnsupportedAccessModeException	Thrown by the DeviceManager to indicate that the looked-up device cannot be opened in the requested access mode.
UnsupportedDeviceTypeException	Thrown by the DeviceManager to indicate permanent unavailability of the looked up device.

Package jdk.dio Description

Provides interfaces and classes for device I/O access and control. Devices are of defined types and can be accessed and control by the means of Device sub-interfaces. Devices are registered under a device ID and with optionally a name and a set of properties.

Unless otherwise noted, passing a null argument to a constructor or method in any class or interface in this package will cause a NullPointerException to be thrown.
