Module Apronext.GeneratorextSource

This file is an extension for the Generator1 module from the apron Library

Note : It only adds function, nothing is removed. Extensions are at the end of the documentation

type t = Apron.Generator1.t
val make : Apron.Linexpr1.t -> Apron.Generator0.typ -> t

Make a generator. Modifying later the linear expression (not advisable) modifies correspondingly the generator and conversely, except for changes of environements

val copy : t -> t

Copy (deep copy)

val print : Format.formatter -> t -> unit

Print the generator

val get_typ : t -> Apron.Generator0.typ

Get the generator type

val iter : (Apron.Coeff.t -> Apron.Var.t -> unit) -> t -> unit

Iter the function on the pair coefficient/variable of the underlying linear expression

val set_typ : t -> Apron.Generator0.typ -> unit

Set the generator type

val set_list : t -> (Apron.Coeff.t * Apron.Var.t) list -> unit

Set simultaneously a number of coefficients.

set_list expr [(c1,"x"); (c2,"y")] assigns coefficients c1 to variable "x" and coefficient c2 to variable "y".

val set_array : t -> (Apron.Coeff.t * Apron.Var.t) array -> unit

Set simultaneously a number of coefficients, as set_list.

val get_coeff : t -> Apron.Var.t -> Apron.Coeff.t

Get the coefficient of the variable in the underlying linear expression

val set_coeff : t -> Apron.Var.t -> Apron.Coeff.t -> unit

Set the coefficient of the variable in the underlying linear expression

val extend_environment : t -> Apron.Environment.t -> t

Change the environement of the generator for a super-environement. Raise Failure if it is not the case

val extend_environment_with : t -> Apron.Environment.t -> unit

Side-effect version of the previous function

Type earray

val array_make : Apron.Environment.t -> int -> Apron.Generator1.earray

Make an array of generators with the given size and defined on the given environement. The elements are initialized with the line 0.

val array_print : ?first:(unit, Format.formatter, unit) format -> ?sep:(unit, Format.formatter, unit) format -> ?last:(unit, Format.formatter, unit) format -> Format.formatter -> Apron.Generator1.earray -> unit

Print an array of generators

val array_length : Apron.Generator1.earray -> int

Get the size of the array

val array_get : Apron.Generator1.earray -> int -> t

Get the element of the given index (which is not a copy)

val array_set : Apron.Generator1.earray -> int -> t -> unit

Set the element of the given index (without any copy). The array and the generator should be defined on the same environement; otherwise a Failure exception is raised.

val array_extend_environment : Apron.Generator1.earray -> Apron.Environment.t -> Apron.Generator1.earray

Change the environement of the array of generators for a super-environement. Raise Failure if it is not the case

val array_extend_environment_with : Apron.Generator1.earray -> Apron.Environment.t -> unit

Side-effect version of the previous function

val get_env : t -> Apron.Environment.t

Get the environement of the generator

val get_linexpr1 : t -> Apron.Linexpr1.t

Get the underlying linear expression. Modifying the linear expression (not advisable) modifies correspondingly the generator and conversely, except for changes of environements

val get_generator0 : t -> Apron.Generator0.t

Get the underlying generator of level 0. Modifying the generator of level 0 (not advisable) modifies correspondingly the generator and conversely, except for changes of environements

Extensions

Sourceval neg : t -> t

constructs a new generator in opposite direction

Sourceval to_float_array : Apron.Generator1.earray -> float array array

Converts a Generator1 into a float array array.

Sourceval of_float_point : Apron.Environment.t -> float list -> t

returns a generator corresponding to a float point
