|
Calculator for summary statistics and aggregates for a list of strings.
|
|
|
|
Statistics are calculated by calling :py:func:`~calculate` and passing a list of strings. The
|
|
individual statistics can then be retrieved using the associated methods. Note that not all statistics
|
|
are calculated by default. Statistics which require slower computations are only calculated by
|
|
specifying the statistic in the constructor or via :py:func:`~setStatistics`.

Adds a single string to the statistics calculation. Calling this method

allows strings to be added to the calculation one at a time. For large

quantities of strings this may be more efficient then first adding all the

strings to a list and calling :py:func:`~QgsStringStatisticalSummary.calculate`.

to clear the results from any previous calculations

.. note::

:py:func:`~QgsStringStatisticalSummary.finalize` must be called after adding the final string and before

retrieving calculated statistics.
