public class TextSet extends Set<String>
Class for representing a set of text values.

"TextSet" objects can be created with a single argument of type string as in MobilityDB.

>>> TextSet(string='{a, b, c, def}')

Another possibility is to create a ``TextSet`` object from a list of strings.

>>> TextSet(elements=['a', 'b', 'c', 'def'])
