Detailed Description

Represents a service to be published.

This class allows you to publish the existence of a network service provided by your application.

If you are providing a web server and want to advertise it on the local network, you might do

KDNSSD::PublicService *service = new KDNSSD::PublicService("My files", "_http._tcp", 80);
bool isOK = service->publish();

In this example publish() is synchronous: it will not return until publishing is complete. This is usually not too long but it can freeze an application's GUI for a moment. To publish asynchronously instead, do:

KDNSSD::PublicService *service = new KDNSSD::PublicService("My files", "_http._tcp", 80);
connect(service, SIGNAL(published(bool)), this, SLOT(wasPublished(bool)));
service->publishAsync();

Constructor & Destructor Documentation

PublicService()

KDNSSD::PublicService::PublicService ( const QString & name = QString(), const QString & type = QString(), unsigned int port = 0, const QString & domain = QString(), const QStringList & subtypes = QStringList() )

explicit

Creates a service description that can be published.

If no name is given, the computer name is used instead. If there is already a service with the same name, type and domain a number will be appended to the name to make it unique.

If no domain is specified, the service is published on the link-local domain (.local).

The subtypes can be used to specify server attributes, such as "_anon" for anonymous FTP servers, or can specify a specific protocol (such as a web service interface) on top of a generic protocol like SOAP.

There is a comprehensive list of possible types available, but you are largely on your own for subtypes.

Parameters

name	a service name to use instead of the computer name
type	service type, in the form _sometype._udp or _sometype._tcp
port	port number, or 0 to "reserve" the service name
domain	the domain to publish the service on (see DomainBrowser)
subtypes	optional list of subtypes, each with a leading underscore

Member Function Documentation

isPublished()

bool KDNSSD::PublicService::isPublished

(

)

const

Whether the service is currently published.

Returns

true if the service is being published to the domain, false otherwise

Definition at line 126 of file avahi-publicservice.cpp.

publish()

bool KDNSSD::PublicService::publish

(

)

Publish the service synchronously.

The method will not return (and hence the application interface will freeze, since KDElibs code should be executed in the main thread) until either the service is published or publishing fails.

published(bool) is emitted before this method returns.

Returns

true if the service was successfully published, false otherwise

Definition at line 132 of file avahi-publicservice.cpp.

publishAsync()

void KDNSSD::PublicService::publishAsync

(

)

Publish the service asynchronously.

Returns immediately and emits published(bool) when completed. Note that published(bool) may be emitted before this method returns when an error is detected immediately.

Definition at line 253 of file avahi-publicservice.cpp.

published

void KDNSSD::PublicService::published ( bool successful )

signal

Emitted when publishing is complete.

It will also emitted when an already-published service is republished after a property of the service (such as the name or port) is changed.

setDomain()

void KDNSSD::PublicService::setDomain

(

const QString &

domain

)

Sets the domain where the service is published.

"local." means link-local, ie: the IP subnet on the LAN containing this computer.

If service is already published, it will be removed from the current domain and published on domain instead.

Parameters

domain

the new domain to publish the service on

Definition at line 70 of file avahi-publicservice.cpp.

setPort()

void KDNSSD::PublicService::setPort

(

unsigned short

port

)

Sets the port.

If the service is already published, it will be re-announced with the new port.

Parameters

port	the port of the service, or 0 to simply "reserve" the name

Definition at line 106 of file avahi-publicservice.cpp.

setServiceName()

void KDNSSD::PublicService::setServiceName

(

const QString &

serviceName

)

Sets the name of the service.

If the service is already published, it will be re-announced with the new name.

Parameters

serviceName

the new name of the service

Definition at line 60 of file avahi-publicservice.cpp.

setSubTypes()

void KDNSSD::PublicService::setSubTypes

(

const QStringList &

subtypes

)

Sets the subtypetypes of the service.

If the service is already published, it will be re-announced with the new subtypes.

The existing list of substypes is replaced, so an empty list will cause all existing subtypes to be removed.

Parameters

subtypes

the new list of subtypes

Definition at line 90 of file avahi-publicservice.cpp.

setTextData()

void KDNSSD::PublicService::setTextData

(

const QMap< QString, QByteArray > &

textData

)

Sets new text properties.

If the service is already published, it will be re-announced with the new data.

Parameters

textData

the new text properties for the service

See also

ServiceBase::textData()

Definition at line 116 of file avahi-publicservice.cpp.

setType()

void KDNSSD::PublicService::setType

(

const QString &

type

)

Sets the service type.

If the service is already published, it will be re-announced with the new type.

Parameters

type	the new type of the service

See PublicService() for details on the format of type

Definition at line 80 of file avahi-publicservice.cpp.

stop()

void KDNSSD::PublicService::stop

(

)

Stops publishing or aborts an incomplete publish request.

Useful when you want to disable the service for some time.

Note that if you stop providing a service (without exiting the application), you should stop publishing it.

Definition at line 142 of file avahi-publicservice.cpp.

subtypes()

QStringList KDNSSD::PublicService::subtypes

(

)

const

The subtypes of service.

virtual_hook()

void KDNSSD::PublicService::virtual_hook ( int , void *  )

overrideprotectedvirtual

Reimplemented from KDNSSD::ServiceBase.
