## 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.
