Package cells :: Module cell

Module cell
source code

Cell, and subclasses of Cell. You will almost certainly never use these directly, instead relying on Model and its subclasses to instantiate these into objects for you.

You should know what these do, though, as you can specify cells.makecell or cells.fun2cell instantiate a specific type of cell for you:

>>> class A(cells.Model):
...     l = cells.makecell(value=[1,3,5], celltype=cells.ListCell)
...     @cells.fun2cell(celltype=cells.RuleThenInputCell)
...     def from_a_global(self, prev):
...         global e
...         return e["something"]
