com.hp.device.AbstractDeviceInfo

All Implemented Interfaces:

DeviceInfo, FacetProvider, MutableDeviceInfo

Direct Known Subclasses:

DefaultDeviceInfo

public abstract class AbstractDeviceInfo
extends Object
implements MutableDeviceInfo

A partial implementation of DeviceInfo that has default implementations of a couple of FacetProvider methods. Note that this class implements MutableDeviceInfo, allowing implementations access to their DeviceType reference.

Constructor Detail

AbstractDeviceInfo

public AbstractDeviceInfo(DefaultDeviceType deviceType)

Creates a device info associated with the specified device type.

Parameters:

deviceType - backing device type

Method Detail

getType

public DefaultDeviceType getType()

Downcast the DeviceType to AbstractDeviceType.

Returns:

the device type downcast

getTypeName

public String getTypeName()

Description copied from interface: DeviceInfo

Returns the name of the device type backing this instance. This method should delegate to the context method of the same name.

Specified by:

getTypeName in interface DeviceInfo

Returns:

the device type name

getFacetClasses

public Set<Class<? extends Facet>> getFacetClasses()

Description copied from interface: FacetProvider

Returns the set of facet classes for the facets that this provider provides.

Specified by:

getFacetClasses in interface FacetProvider

Returns:

the set of facet classes

getFacetClassNames

public Set<String> getFacetClassNames()

Description copied from interface: FacetProvider

Returns the set of facet class names for the facets that this provider provides. Implementations should iterate across their implementation of FacetProvider.getFacetClasses() and populate the returned set with the result of calling Class.getName() on each class.

Specified by:

getFacetClassNames in interface FacetProvider

Returns:

the set of facet class names

isSupported

public boolean isSupported(Class<? extends Facet> facetClass)

Description copied from interface: FacetProvider

Returns true if the specified facet class is supported by this provider. The following implementation (or its equivalent) should hold true:

 public boolean isSupported(Class<? extends Facet> facetClass) {
     return FacetProvider.getFacetClasses()().contains(facetClass);
 }
 

Specified by:

isSupported in interface FacetProvider

Parameters:

facetClass - a facet class

Returns:

true if this provider supports that class of facet

getFacet

public <T extends Facet> T getFacet(Class<T> facetClass)

Description copied from interface: FacetProvider

Returns an implementation of the specified facet class, or null if that facet is not supported by this provider.

Specified by:

getFacet in interface FacetProvider

Type Parameters:

T - Facet type

Parameters:

facetClass - the class of the required facet

Returns:

a facet implementation

getDeviceType

public DeviceType getDeviceType()

Description copied from interface: MutableDeviceInfo

Returns the device type that this device info instance is backed by.

Specified by:

getDeviceType in interface MutableDeviceInfo

Returns:

the device type

setDeviceType

public void setDeviceType(DeviceType type)

Description copied from interface: MutableDeviceInfo

Sets the device type for this device info instance.

Specified by:

setDeviceType in interface MutableDeviceInfo

Parameters:

type - the device type
