Interface DriverData

All Superinterfaces:

Annotations, MutableAnnotations

All Known Implementing Classes:

AbstractProjectableModel.AnnotationDriverData, DefaultDevice.DeviceDriverData, DefaultDriverData

public interface DriverData
extends MutableAnnotations

Container for data about an entity, e.g. device, link. Data is stored using MutableAnnotations. Note that only derivatives of HandlerBehaviour can expect mutability from the backing driver data instance; other behaviours must rely on immutable Annotations only.

Method Summary

Modifier and Type	Method and Description
default <T extends Behaviour> T	behaviour(java.lang.Class<T> behaviourClass) Returns the specified facet of behaviour to access the device data.
DeviceId	deviceId() Returns the device identifier.
Driver	driver() Returns the parent device driver.

Method Detail

driver

Driver driver()

Returns the parent device driver.

Returns:

device driver

deviceId

DeviceId deviceId()

Returns the device identifier.

Returns:

device identifier

behaviour

default <T extends Behaviour> T behaviour(java.lang.Class<T> behaviourClass)

Returns the specified facet of behaviour to access the device data. Implementations are expected to defer to the backing driver for creation of the requested behaviour.

Type Parameters:

T - type of behaviour

Parameters:

behaviourClass - behaviour class

Returns:

requested behaviour or null if not supported
