-- This child package of Ada.Strings.Unbounded provides some specialized
-- Text_IO routines that work directly with unbounded strings, avoiding the
-- inefficiencies of access via the standard interface, and also taking
-- direct advantage of the variable length semantics of these strings.
with Ada.Text_IO;
package Ada.Strings.Unbounded.Text_IO is
function Get_Line return Unbounded_String;
function Get_Line (File : Ada.Text_IO.File_Type) return Unbounded_String;
-- Reads up to the end of the current line, returning the result
-- as an unbounded string of appropriate length. If no File parameter
-- is present, input is from Current_Input.
procedure Get_Line
(File : Ada.Text_IO.File_Type;
Item : out Unbounded_String);
procedure Get_Line (Item : out Unbounded_String);
-- Similar to the above, but in procedure form with an out parameter
procedure Put (U : Unbounded_String);
procedure Put (File : Ada.Text_IO.File_Type; U : Unbounded_String);
procedure Put_Line (U : Unbounded_String);
procedure Put_Line (File : Ada.Text_IO.File_Type; U : Unbounded_String);
-- These are equivalent to the standard Text_IO routines passed the
-- value To_String (U), but operate more efficiently, because the extra
-- copy of the argument is avoided.
