Describes a service.
This class is used to describe a service. The service can be published by the current application (in which case it is probably a PublicService) or by another application, either on the current machine or a remote machine, in which case it is probably a RemoteService returned by ServiceBrowser.
You should not normally need to create a ServiceBase object yourself.

Creates a ServiceBase object.
Note that name
, type
and domain
uniquely identify the service in the DNS-SD system, and host
and port
provide the actual location of the service.
For example, RemoteService populates host
and port
based on the name
, type
and domain
attributes using the DNS-SD resolution system.
name | service name |
type | service type |
domain | the DNS-SD domain name for service |
host | the host name of the service (a fully-qualified domain name) |
port | the port number of the service |
QString KDNSSD::ServiceBase::domain | ( | ) | const |
The domain that the service belongs to.
It is "local." for link-local services.
QString KDNSSD::ServiceBase::hostName | ( | ) | const |
The hostname of the service.
Only valid for local and resolved remote services.
Together with port(), this can be used to actually access the service.
bool KDNSSD::ServiceBase::operator!= | ( | const ServiceBase & | o | ) | const |
Compares services based on name, type and domain.
This is enough to for unique identification and omitting port, host and text data allows to compare resolved and unresolved services
o | the service to compare this service to |
false
if this service represents the same service (from the point of view of DNS-SD) as o
, true
otherwise bool KDNSSD::ServiceBase::operator== | ( | const ServiceBase & | o | ) | const |
Compares services based on name, type and domain.
This is enough to for unique identification and omitting port, host and text data allows to compare resolved and unresolved services
o | the service to compare this service to |
true
if this service represents the same service (from the point of view of DNS-SD) as o
, false
otherwise unsigned short KDNSSD::ServiceBase::port | ( | ) | const |
The port number of the service.
Only valid for local and resolved remote services.
Together with hostName(), this can be used to actually access the service.
QString KDNSSD::ServiceBase::serviceName | ( | ) | const |
The name of the service.
QMap< QString, QByteArray > KDNSSD::ServiceBase::textData | ( | ) | const |
Additional text data associated with the service.
Only valid for local and resolved remote services.
This is data that provides additional information about the service. For example, it might be used to specify a printer queue on the printer server specified by hostName() and port().
You can check for the data that might be associated with a particular service on the service types list. If a key=value
pair is given, this will appear with the value
in a QByteArray indexed by the key
. If the data is on its own (does not have an =
in it), it will be used to index an empty QByteArray, and can be checked for with QMap::contains().
For example, if you are accessing the _ipp._tcp service, you might do something like
since the TXT data of the IPP service may contain data like "ty=Apple LaserWriter Pro 630". Note that you actually have to be a bit more clever than this, since the key should usually be case insensitive.
QString KDNSSD::ServiceBase::type | ( | ) | const |
The type of the service.
This is always in the format _sometype._udp or _sometype._tcp.
See the DNS-SD website for a full list of service types.
