Known Subclasses:

MapRule
, VarDef

a base class for map and var.

You must give a destDict class attribute to make these work.

Nested Classes
Inherited from `base.structure.StructureBase`: `__metaclass__`, `name_`

Instance Methods

completeElement(self, ctx)

source code

validate(self)
checks that code content is a parseable python expression and that the destination exists in the tableDef

source code

getCode(self, columns)
returns python source code for this map.
