Detailed Description

The QXmppUtils class contains static utility functions.

Member Function Documentation

datetimeFromString()

QDateTime QXmppUtils::datetimeFromString ( const QString &  str )

static

Parses a date-time from a string according to XEP-0082: XMPP Date and Time Profiles.

datetimeToString()

QString QXmppUtils::datetimeToString ( const QDateTime &  dt )

static

Serializes a date-time to a string according to XEP-0082: XMPP Date and Time Profiles.

generateRandomBytes()

QByteArray QXmppUtils::generateRandomBytes ( int  length )

static

Returns a random byte array of the specified size.

Parameters

length

generateRandomInteger()

int QXmppUtils::generateRandomInteger ( int  N )

static

Generates a random integer x between 0 and N-1.

Parameters

N

generateStanzaHash()

QString QXmppUtils::generateStanzaHash ( int  length = 36 )

static

Returns a random alphanumerical string of the specified size.

Since QXmpp 1.3 this will generate a UUID, if the specified length is 36 which is also the new default value. The returned string is still 36 characters long, but will contain dashes (as specified in the UUID format).

Note

It is recommended to use UUIDs for cases where IDs must be unique and are possibly stored permanently. This can be done using QXmppUtils::generateStanzaUuid(). However, since that function is only available since QXmpp 1.3, you may also want to continue to use this function because of compatibility reasons.

Parameters

length

generateStanzaUuid()

QString QXmppUtils::generateStanzaUuid ( )

static

Creates a new stanza id in the UUID format.

Since

QXmpp 1.3

timezoneOffsetFromString()

int QXmppUtils::timezoneOffsetFromString ( const QString &  str )

static

Parses a timezone offset (in seconds) from a string according to XEP-0082: XMPP Date and Time Profiles.

timezoneOffsetToString()

QString QXmppUtils::timezoneOffsetToString ( int  secs )

static

Serializes a timezone offset (in seconds) to a string according to XEP-0082: XMPP Date and Time Profiles.
