ITcore API
From Intoj.org
The API of ITcore is designed in a demand-driven fashion: initially, applications are allowed to access the internals of ITcore; once an application has stabilized, this access is refactored into the API. intoJ tools are used for this refactoring.
Basically, the API divides into methods for creating a constraint net from a (set of) declaration element(s) and methods for solving the constraints as well as extracting the solution.
