public DefaultDeviceHandler(AbstractDeviceInfo deviceInfo,
                    IpAddress ip)

Create a device handler for the specified device info and IP address.

Parameters:

deviceInfo - device info context

ip - IP address of the target device

Method Detail

getDeviceInfo

public DeviceInfo getDeviceInfo()

Description copied from interface: DeviceHandler

Returns the DeviceInfo instance associated with this handler.

Specified by:

getDeviceInfo in interface DeviceHandler

Returns:

the device info instance

getIpAddress

public IpAddress getIpAddress()

Description copied from interface: DeviceHandler

Returns the IP address of the device to which this handler is bound.

Specified by:

getIpAddress in interface DeviceHandler

Returns:

the device IP address

toString

public String toString()

Overrides:

toString in class Object

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
