Detailed Description

The QDnsServiceRecord class stores information about a DNS SRV record.

When performing a lookup on a service, zero or more records will be returned. Each record is represented by a QDnsServiceRecord instance.

The meaning of the fields is defined in RFC 2782.

Member Function Documentation


Constructs an empty service record object.

QDnsServiceRecord::QDnsServiceRecord(const QDnsServiceRecord &other)

Constructs a copy of other.


Destroys a service record.

QString QDnsServiceRecord::name() const

Returns the name for this record.

quint16 QDnsServiceRecord::port() const

Returns the port on the target host for this service record.

quint16 QDnsServiceRecord::priority() const

Returns the priority for this service record.

A client must attempt to contact the target host with the lowest-numbered priority.

void QDnsServiceRecord::swap(QDnsServiceRecord &other)

Swaps this service record instance with other. This function is very fast and never fails.

QString QDnsServiceRecord::target() const

Returns the domain name of the target host for this service record.

quint32 QDnsServiceRecord::timeToLive() const

Returns the duration in seconds for which this record is valid.

quint16 QDnsServiceRecord::weight() const

Returns the weight for this service record.

The weight field specifies a relative weight for entries with the same priority. Entries with higher weights should be selected with a higher probability.

QDnsServiceRecord &QDnsServiceRecord::operator=(QDnsServiceRecord &&other)

Move-assignment operator.

QDnsServiceRecord &QDnsServiceRecord::operator=(const QDnsServiceRecord &other)

Assigns the data of the other object to this record object, and returns a reference to it.
