Interface UPnPDevice

public interface UPnPDevice

Represents a UPnP device. For each UPnP root and embedded device, an object is registered with the framework under the UPnPDevice interface.

The relationship between a root device and its embedded devices can be deduced using the UPnPDevice.CHILDREN_UDN and UPnPDevice.PARENT_UDN service registration properties.

The values of the UPnP property names are defined by the UPnP Forum.

All values of the UPnP properties are obtained from the device using the device's default locale.

If an application wants to query for a set of localized property values, it has to use the method UPnPDevice.getDescriptions(String locale).

Constant Field Values

UDN

public static final java.lang.String UDN

Property key for the Unique Device Name (UDN) property. It is the unique identifier of an instance of a UPnPDevice. The value of the property is a String object of the Device UDN. Value of the key is "UPnP.device.UDN". This property must be set.

See Also:

Constant Field Values

ID

public static final java.lang.String ID

Property key for the Unique Device ID property. This property is an alias to UPnPDevice.UDN. It is merely provided for reasons of symmetry with the UPnPService.ID property. The value of the property is a String object of the Device UDN. The value of the key is "UPnP.device.UDN".

See Also:

Constant Field Values

TYPE

public static final java.lang.String TYPE

Property key for the UPnP Device Type property. Some standard property values are defined by the Universal Plug and Play Forum. The type string also includes a version number as defined in the UPnP specification. This property must be set.

For standard devices defined by a UPnP Forum working committee, this must consist of the following components in the given order separated by colons:

• urn
• schemas-upnp-org
• device
• a device type suffix
• an integer device version

For non-standard devices specified by UPnP vendors following components must be specified in the given order separated by colons:

• urn
• an ICANN domain name owned by the vendor
• device
• a device type suffix
• an integer device version

To allow for backward compatibility the UPnP driver must automatically generate additional Device Type property entries for smaller versions than the current one. If for example a device announces its type as version 3, then properties for versions 2 and 1 must be automatically generated.

In the case of exporting a UPnPDevice, the highest available version must be announced on the network.

Syntax Example: urn:schemas-upnp-org:device:deviceType:v

The value is "UPnP.device.type".

Method Detail

getService

public UPnPService getService(java.lang.String serviceId)

Locates a specific service by its service id.

Parameters:

serviceId - The service id

Returns:

The requested service or null if not found.

getServices

public UPnPService[] getServices()

Lists all services provided by this device.

Returns:

Array of services or null if no services are available.

getIcons

public UPnPIcon[] getIcons(java.lang.String locale)

Lists all icons for this device in a given locale. The UPnP specification allows a device to present different icons based on the client's locale.

Parameters:

locale - A language tag as defined by RFC 1766 and maintained by ISO 639. Examples include "de", "en" or "en-US". The default locale of the device is specified by passing a null argument.

Returns:

Array of icons or null if no icons are available.

getDescriptions

public java.util.Dictionary getDescriptions(java.lang.String locale)

Get a set of localized UPnP properties. The UPnP specification allows a device to present different device properties based on the client's locale. The properties used to register the UPnPDevice service in the OSGi registry are based on the device's default locale. To obtain a localized set of the properties, an application can use this method.

Not all properties might be available in all locales. This method does not substitute missing properties with their default locale versions.

Parameters:

locale - A language tag as defined by RFC 1766 and maintained by ISO 639. Examples include "de", "en" or "en-US". The default locale of the device is specified by passing a null argument.

Returns:

Dictionary mapping property name Strings to property value Strings
