Field accessors

Accessors are used to model methods used to access data defined by fields. Accessors are fields that work by decorating existing fields.

 class IMyInterface(Interface):

    getFoo, setFoo = accessors(Text(title=u'Foo', ...))

    getBar, = accessors(TextLine(title=u'Foo', readonly=True, ...)

Normally a read accessor and a write accessor are defined. Only a read accessor is defined for read-only fields.

Read accessors function as access method specifications and as field specifications. Write accessors are solely method specifications.
