val make : Linexpr1.t -> Generator0.typ -> t
Make a generator. Modifying later the linear expression (not advisable) modifies correspondingly the generator and conversely, except for changes of environments
val copy : t -> t
Copy (deep copy)
val print : Stdlib.Format.formatter -> t -> unit
Print the generator
val get_typ : t -> Generator0.typ
Get the generator type
val iter : (Coeff.t -> Var.t -> unit) -> t -> unit
Iter the function on the pair coefficient/variable of the underlying linear expression
val set_typ : t -> Generator0.typ -> unit
Set the generator type
val set_list : t -> (Coeff.t * 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 -> (Coeff.t * Var.t) array -> unit
Set simultaneously a number of coefficients, as set_list
.
val get_coeff : t -> Var.t -> Coeff.t
Get the coefficient of the variable in the underlying linear expression
val set_coeff : t -> Var.t -> Coeff.t -> unit
Set the coefficient of the variable in the underlying linear expression
val extend_environment : t -> Environment.t -> t
Change the environment of the generator for a super-environment. Raise Failure
if it is not the case
val extend_environment_with : t -> Environment.t -> unit
Side-effect version of the previous function
val array_make : Environment.t -> int -> earray
Make an array of generators with the given size and defined on the given environment. The elements are initialized with the line 0.
val array_print : ?first:(unit, Stdlib.Format.formatter, unit) Stdlib.format ->
?sep:(unit, Stdlib.Format.formatter, unit) Stdlib.format ->
?last:(unit, Stdlib.Format.formatter, unit) Stdlib.format ->
Stdlib.Format.formatter -> earray -> unit
Print an array of generators
val array_length : earray -> int
Get the size of the array
val array_get : earray -> int -> t
Get the element of the given index (which is not a copy)
val array_set : 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 environment; otherwise a Failure
exception is raised.
val array_extend_environment : earray -> Environment.t -> earray
Change the environment of the array of generators for a super-environment. Raise Failure
if it is not the case
val array_extend_environment_with : earray -> Environment.t -> unit
Side-effect version of the previous function
val get_env : t -> Environment.t
Get the environment of the generator
val get_linexpr1 : t -> Linexpr1.t
Get the underlying linear expression. Modifying the linear expression (not advisable) modifies correspondingly the generator and conversely, except for changes of environments
val get_generator0 : t -> 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 environments
