An assignment for an equation system is a map from unknowns to values.
This is the type for the body of an equation system, i.e., a map which takes an assignment of values to unknowns and returns a new assignment of values to unknowns.

A Box is a way to combine two values into a new one.
A Box is a way to combine two values into a new one. It is a specialization of the functional type
(V,V) => V
, where the first parameter is the old value of an unknown and the second parameter
is the new contribution. Both widenings and narrowings are examples of boxes. Boxes are mutable, i.e.,
the apply method may give different results for the same input when called multiple times.
Another function of boxes is to be blueprints for building other equivalent boxes. Each box has a copy
method which should produce a functionally equivalent copy of this
. The copy method should try to
minimize object duplication.
the type of the values to combine.
A BoxAssignment maps a subset of the program's points to a Box.
A BoxAssignment maps a subset of the program's points to a Box. When isDefinedAt(u)
is false for a given unknown u
, the corresponding apply(u)
should be a right box.
Like it was the case for Box, a BoxAssignent is also a blueprint for buildind equivalent
BoxAssignments. Each BoxAssignmant has a copy method which should produce a functionally
equivalent copy of this
. The copy method should try to minimize object duplication.

This abstract class implements a listener for fixpoint solvers which does nothing.
This abstract class implements a listener for fixpoint solvers which does nothing. May be sub-classed in order to override only the methods we are interested in.
A partial assignment for an equation system is an iterable function from unknowns to values.
The Body
object defines several factories for building bodies.
The Box
object defines several factories for building boxes.
The BoxAssignment
object defines factories for building box assignments.
The FixpointSolver
object contains many enumerations and auxiliary classes which are used by
other fixpoint solvers.
The fixpoint package contains everything which is related to defining and solving systems of equations. This package object defines some type aliases which are used in the API.
