Detailed Description
Utils::Id is used as facility to identify objects of interest in a more typesafe and faster manner than a plain QString or QByteArray would provide.
An id is associated with a plain 7-bit-clean ASCII name used for display and persistency.
Member Function Documentation
[static] Utils::Id Id::fromSetting(const QVariant &variant)
Reconstructs an id from the persistent value variant.
See also toSetting().
QByteArrayView Id::name() const
Returns an internal representation of the id.
QString Id::suffixAfter(Utils::Id baseId) const
Extracts a part of the id string representation. This function can be used to split off the base part specified by baseId used when generating an id with withSuffix().
See also withSuffix().
QVariant Id::toSetting() const
Returns a persistent value representing the id which is suitable to be stored in QSettings.
See also fromSetting().
QString Id::toString() const
Returns a string representation of the id suitable for UI display.
This should not be used to create a persistent version of the Id, use toSetting() instead.
See also fromString() and toSetting().
Utils::Id Id::withPrefix(const char *prefix) const
Constructs a derived id.
This can be used to construct groups of ids logically belonging together. The associated internal name will be generated by prepending prefix.
Utils::Id Id::withSuffix(qsizetype suffix) const
Constructs a derived id.
This can be used to construct groups of ids logically belonging together. The associated internal name will be generated by appending suffix.
Utils::Id Id::withSuffix(int suffix) const
This is an overloaded function.
Utils::Id Id::withSuffix(char suffix) const
This is an overloaded function.
Utils::Id Id::withSuffix(const char *suffix) const
This is an overloaded function.
Utils::Id Id::withSuffix(QStringView suffix) const
This is an overloaded function.
