Detailed Description

This class is most important for application that wants to announce its service on network.

Suppose that you want to make your web server public - this is simplest way:

DNSSD::PublicService *service = new DNSSD::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 application's GUI for a moment. Asynchronous publishing is better for responsiveness. Example:

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

This class represents local service being published

Constructor & Destructor Documentation

DNSSD::PublicService::PublicService	(	const QString &	name = QString::null,
		const QString &	type = QString::null,
		unsigned int	port = 0,
		const QString &	domain = QString::null
	)

Parameters:

	name	Service name. If set to QString::null, computer name will be used and will be available via serviceName() after successful registration
	type	Service type. Has to be in form _sometype._udp or _sometype._tcp
	port	Port number. Set to 0 to "reserve" service name.
	domain	Domain name. If left as QString:null, user configuration will be used. "local." means local LAN

Member Function Documentation

void DNSSD::PublicService::customEvent

(

QCustomEvent *

event

)

[protected, virtual]

Reimplemented from QObject.

Definition at line 195 of file publicservice.cpp.

bool DNSSD::PublicService::isPublished

(

)

const

Returns true is currently published.

Definition at line 107 of file publicservice.cpp.

bool DNSSD::PublicService::publish

(

)

Synchrounous publish.

Application will be freezed until publishing is complete.

Returns:

true if successfull.

Definition at line 121 of file publicservice.cpp.

void DNSSD::PublicService::publishAsync

(

)

Asynchronous version of publish().

It return immediately and emits signal published(bool) when completed. Note that in case of early detected error (like bad service type) signal may be emitted before return of this function.

Definition at line 134 of file publicservice.cpp.

void DNSSD::PublicService::published

(

bool

)

[signal]

Emitted when publishing is complete - parameter is set to true if it was successfull.

It will also emitted when name, port or type of already published service is changed.

void DNSSD::PublicService::setDomain

(

const QString &

domain

)

Sets domain where service is published.

"local." means local LAN. If service is currently published, it will be re-announced with new data.

Definition at line 79 of file publicservice.cpp.

void DNSSD::PublicService::setPort

(

unsigned short

port

)

Sets port.

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

Definition at line 98 of file publicservice.cpp.

void DNSSD::PublicService::setServiceName

(

const QString &

serviceName

)

Sets name of the service.

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

Definition at line 70 of file publicservice.cpp.

void DNSSD::PublicService::setTextData

(

const QMap< QString, QString > &

textData

)

Sets new text properties.

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

Definition at line 112 of file publicservice.cpp.

void DNSSD::PublicService::setType

(

const QString &

type

)

Sets type of service.

It has to in form of _type._udp or _type._tcp. If service is currently published, it will be re-announced with new data.

Definition at line 89 of file publicservice.cpp.

void DNSSD::PublicService::stop

(

)

Stops publishing or abort incomplete publish request.

Useful when you want to disable service for some time.

Definition at line 128 of file publicservice.cpp.

const KURL DNSSD::PublicService::toInvitation

(

const QString &

host = QString::null

)

Translates service into URL that can be sent to another user.

Parameters:

host

Use specified hostname. If left empty, public IP address (the one used for default route) will be used.

Since:

3.5

void DNSSD::PublicService::virtual_hook	(	int	,
		void *
	)			[protected, virtual]

Reimplemented from DNSSD::ServiceBase.

Definition at line 208 of file publicservice.cpp.
