QgsNumericFormat * QgsBasicNumericFormat::clone ( ) const

overridevirtual

Clones the format, returning a new object.

The caller takes ownership of the returned object.

Implements QgsNumericFormat.

Reimplemented in QgsBearingNumericFormat, QgsGeographicCoordinateNumericFormat, QgsCurrencyNumericFormat, QgsPercentageNumericFormat, and QgsScientificNumericFormat.
