Module enthought.block_canvas.function_tools.function

API Reference for Enthought Tool Suite 3.0.1

Classes to represent function input and output variables along with "bindings" (variable names or values) to them. There are also classes that store information about the units of a variable.

Note: The Variable class could "grow" another trait called "unique_name": or something like that to handle re-writing of variables to enforce uniqueness during execution.
