Field Detail

TYPE

static final String TYPE

Property key for the optional service type uri. The service type property is used when registering UPnP Device services and UPnP Event Listener services. The property contains a String array (String[]) of service types. A UPnP Device service can thus announce what types of services it contains. A UPnP Event Listener service can announce for what type of UPnP services it wants notifications. The service version is encoded in the type string as specified in the UPnP specification. A null value is a wildcard, matching all service types. Value is "UPnP.service.type".

ID

static final String ID

Property key for the optional service id. The service id property is used when registering UPnP Device services or UPnP Event Listener services. The value of the property contains a String array (String[]) of service ids. A UPnP Device service can thus announce what service ids it contains. A UPnP Event Listener service can announce for what UPnP service ids it wants notifications. A service id does not have to be universally unique. It must be unique only within a device. A null value is a wildcard, matching all services. The value is "UPnP.service.id".

Method Detail

getId

String getId()

Returns the serviceId field in the UPnP service description.

For standard services defined by a UPnP Forum working committee, the serviceId must contain the following components in the indicated order:

• urn:upnp-org:serviceId:
• service ID suffix

Example: urn:upnp-org:serviceId:serviceID.

Note that upnp-org is used instead of schemas-upnp-org in this example because an XML schema is not defined for each serviceId.

For non-standard services specified by UPnP vendors, the serviceId must contain the following components in the indicated order:

• urn:
• ICANN domain name owned by the vendor
• :serviceId:
• service ID suffix

Example: urn:domain-name:serviceId:serviceID.

This method must continue to return the service id after the UPnP service has been removed from the network.

Returns:

The service ID suffix defined by a UPnP Forum working committee or specified by a UPnP vendor. Must be <= 64 characters. Single URI.

getType

String getType()

Returns the serviceType field in the UPnP service description.

For standard services defined by a UPnP Forum working committee, the serviceType must contain the following components in the indicated order:

• urn:schemas-upnp-org:service:
• service type suffix:
• integer service version

Example: urn:schemas-upnp-org:service:serviceType:v.

For non-standard services specified by UPnP vendors, the serviceType must contain the following components in the indicated order:

• urn:
• ICANN domain name owned by the vendor
• :service:
• service type suffix:
• integer service version

Example: urn:domain-name:service:serviceType:v.

This method must continue to return the service type after the UPnP service has been removed from the network.

Returns:

The service type suffix defined by a UPnP Forum working committee or specified by a UPnP vendor. Must be <= 64 characters, not including the version suffix and separating colon. Single URI.

getVersion

String getVersion()

Returns the version suffix encoded in the serviceType field in the UPnP service description.

This method must continue to return the service version after the UPnP service has been removed from the network.

Returns:

The integer service version defined by a UPnP Forum working committee or specified by a UPnP vendor.
