Module Stream
: sig end
Streams and parsers.
type 'a t
The type of streams holding values of type 'a .
exception Failure
Raised by parsers when none of the first components of the stream patterns is accepted.
exception Error of string
Raised by parsers when the first component of a stream pattern is accepted, but one of the following components is rejected.
=== Stream builders Warning: these functions create streams with fast access; it is illegal to mix them with streams built with [< >];
would raise Failure when accessing such mixed streams. ===
val from : (int -> 'a option) -> 'a t
Stream.from f returns a stream built from the function f . To create a new stream element, the function f is called with the current
stream count. The user function f must return either Some <value> for a value or None to specify the end of the stream.
val of_list : 'a list -> 'a t
Return the stream holding the elements of the list in the same order.
val of_string : string -> char t
Return the stream of the characters of the string parameter.
val of_channel : Pervasives.in_channel -> char t
Return the stream of the characters read from the input channel.
=== Stream iterator ===
val iter : ('a -> unit) -> 'a t -> unit
Stream.iter f s scans the whole stream s, applying function f in turn to each stream element encountered.
=== Predefined parsers ===
val next : 'a t -> 'a
Return the first element of the stream and remove it from the stream. Raise Stream.Failure if the stream is empty.
val empty : 'a t -> unit
Return () if the stream is empty, else raise Stream.Failure .
=== Useful functions ===
val peek : 'a t -> 'a option
Return Some of "the first element" of the stream, or None if the stream is empty.
val junk : 'a t -> unit
Remove the first element of the stream, possibly unfreezing it before.
val count : 'a t -> int
Return the current count of the stream elements, i.e. the number of the stream elements discarded.
val npeek : int -> 'a t -> 'a list
npeek n returns the list of the n first elements of the stream, or all its remaining elements if less than n elements are available.
