Class enthought.traits.trait_handlers.TraitString

API Reference for Enthought Tool Suite 2.7.1

Ensures that a trait attribute value is a string that satisfied some additional, optional constraints.

The optional constraints include minimum and maximum lengths, and a regular expression that the string must match.

If the value assigned to the trait attribute is a Python numeric type, the TraitString handler first coerces the value to a string. Values of other non-string types result in a TraitError being raised. The handler then makes sure that the resulting string is within the specified length range and that it matches the regular expression.
