Class enthought.traits.trait_handlers.TraitCompound

API Reference for Enthought Tool Suite 2.7.1

Provides a logical-OR combination of other trait handlers.

This class provides a means of creating complex trait definitions by combining several simpler trait definitions. TraitCompound is the underlying handler for the general forms of the Trait() function.

A value is a valid value for a trait attribute based on a TraitCompound instance if the value is valid for at least one of the TraitHandler or trait objects supplied to the constructor. In addition, if at least one of the TraitHandler or trait objects is mapped (e.g., based on a TraitMap or TraitPrefixMap instance), then the TraitCompound is also mapped. In this case, any non-mapped traits or trait handlers use identity mapping.
