Class enthought.​tvtk.​tvtk_base.​TraitRevPrefixMap

A reverse mapped TraitPrefixMap. This handler allows for something like the following:

>>> class A(HasTraits):
...     a = Trait('ab', TraitRevPrefixMap({'ab':1, 'cd':2}))
...
>>> a = A()
>>> a.a = 'c'
>>> print a.a
'cd'
>>> a.a = 1
>>> print a.a
'ab'

That is, you can set the trait to the value itself. If multiple keys map to the same value, one of the valid keys will be used.
