Detailed Description

Lookup a host.

About Zero Config

This class handles lookup of a host. It can be booth Multicast and Unicast DNS lookup.

Example usage

    ArnZeroConfLookup*  ds = new ArnZeroConfLookup("myhost.local", this);
    ds->setId( myId);  // Optional id, later used in the signals
    connect( ds, SIGNAL(lookupError(int,int)), this, SLOT(onLookupError(int,int)));
    connect( ds, SIGNAL(lookuped(int)), this, SLOT(onLookuped(int)));
    ds->lookup();
void  XXX::onLookuped( int id)
{
    ArnZeroConfLookup*  ds = qobject_cast<ArnZeroConfLookup*>( sender());
    QString  hostName = ds->host();
    QHostAddress  hostIp = ds->hostAddr();
    ds->releaseLookup();
    ds->deleteLater();
}

Constructor & Destructor Documentation

◆ ArnZeroConfLookup() [1/2]

ArnZeroConfLookup::ArnZeroConfLookup ( QObject * parent = arnNullptr )

Standard constructor of an ArnZeroConfLookup object.

Parameters

[in] parent

Definition at line 690 of file ArnZeroConf.cpp.

◆ ArnZeroConfLookup() [2/2]

ArnZeroConfLookup::ArnZeroConfLookup	(	const QString &	hostName,
		QObject *	parent = `arnNullptr`
	)

Constructor of an ArnZeroConfLookup object.

All needed parameters for a lookup of a host.

Parameters

[in]	hostName	the name of the host.
[in]	parent

Definition at line 697 of file ArnZeroConf.cpp.

◆ ~ArnZeroConfLookup()

ArnZeroConfLookup::~ArnZeroConfLookup ( )

virtual

Destructor of an ArnZeroConfLookup object.

If the lookup is ongoing, it will be released.

Definition at line 706 of file ArnZeroConf.cpp.

Member Function Documentation

◆ host()

QString ArnZeroConfLookup::host ( ) const

inline

Returns the host name for this Lookup.

Returns: current host name

See also: setHost()

Definition at line 824 of file ArnZeroConf.hpp.

◆ hostAddr()

QHostAddress ArnZeroConfLookup::hostAddr ( ) const

inline

Returns the host address for this Lookup.

Returns: current host adress

Definition at line 838 of file ArnZeroConf.hpp.

◆ id()

int ArnZeroConfLookup::id ( ) const

Returns the id number for this lookup.

Return values

the id number

See also: setId()

Definition at line 716 of file ArnZeroConf.cpp.

◆ isForceQtDnsLookup()

bool ArnZeroConfLookup::isForceQtDnsLookup ( )

static

Return Force using Qt for DNS lookup.

Return values

true	if Force using Qt for DNS lookup

See also: setForceQtDnsLookup()

Definition at line 875 of file ArnZeroConf.cpp.

◆ lookup()

void ArnZeroConfLookup::lookup ( bool forceMulticast = false )

Lookup the host address.

Tries to lookup the host address necessary to establish a connection.

Result is indicated by lookuped() and lookupError() signals.

Parameters

[in] forceMulticast when true, ArnZeroConfLookup will use a mDns request to lookup the host address, even if the host name is a unicast address, i.e. outside the local network.

See also: lookuped(); lookupError()

Definition at line 728 of file ArnZeroConf.cpp.

◆ lookuped

void ArnZeroConfLookup::lookuped ( int id )

signal

Indicate successfull lookup of host.

Parameters

[in] id is the id number for this lookup

See also: lookup()

◆ lookupError

void ArnZeroConfLookup::lookupError	(	int	id,
		int	code
	)

signal

Indicate unsuccessfull lookup of host.

Parameters

[in]	id	is the id number for this lookup
[in]	code	error code.

See also: lookup()

◆ releaseLookup()

void ArnZeroConfLookup::releaseLookup ( )

Release the lookup.

Any lookup attempts in progress will be aborted.

Definition at line 784 of file ArnZeroConf.cpp.

◆ setForceQtDnsLookup()

void ArnZeroConfLookup::setForceQtDnsLookup ( bool isForceQtDnsLookup )

static

Set Force using Qt for DNS lookup.

If mDns lookup doesn't work for a platform, try force using Qt:s built in DNS-lookup.

This is a global setting for all instances of ArnZeroConfLookup.

Parameters

[in] isForceQtDnsLookup

See also: isForceQtDnsLookup()

Definition at line 881 of file ArnZeroConf.cpp.

◆ setHost()

void ArnZeroConfLookup::setHost ( const QString & host )

inline

Set the host name for this Lookup.

Usually hostname contain domain, e.g. "myserver.local" but it can also be "myserver".

Parameters

[in] host is the current host name (se above)

See also: host()

Definition at line 832 of file ArnZeroConf.hpp.

◆ setId()

void ArnZeroConfLookup::setId ( int id )

Sets the id number for this this lookup.

This id can be used to identify different lookup:s when using a common handler.

When not set, it will be automatically asigned during lookup().

Parameters

[in] id the id number

See also: id()

Definition at line 722 of file ArnZeroConf.cpp.
