| 32 -- This child package of Ada.Strings.Wide_Wide_Unbounded provides some | |
| 33 -- specialized access functions which are intended to allow more efficient | |
| 34 -- use of the facilities of Ada.Strings.Wide_Wide_Unbounded, particularly by | |
| 35 -- other layered utilities. | |
| 36 | |
| 37 package Ada.Strings.Wide_Wide_Unbounded.Aux is | |
| 38 pragma Preelaborate; | |
| 39 | |
| 40 subtype Big_Wide_Wide_String is Wide_Wide_String (Positive); | |
| 41 type Big_Wide_Wide_String_Access is access all Big_Wide_Wide_String; | |

| 43 procedure Get_Wide_Wide_String | |
| 44 (U : Unbounded_Wide_Wide_String; | |
| 45 S : out Big_Wide_Wide_String_Access; | |
| 46 L : out Natural); | |
| 47 pragma Inline (Get_Wide_Wide_String); | |
| 48 -- This procedure returns the internal string pointer used in the | |
| 49 -- representation of an unbounded string as well as the actual current | |
| 50 -- length (which may be less than S.all'Length because in general there | |
| 51 -- can be extra space assigned). The characters of this string may be | |
| 52 -- not be modified via the returned pointer, and are valid only as | |
| 53 -- long as the original unbounded string is not accessed or modified. | |
| 54 -- | |
| 55 -- This procedure is more efficient than the use of To_Wide_Wide_String | |
| 56 -- since it avoids the need to copy the string. The lower bound of the | |
| 57 -- referenced string returned by this call is always one, so the actual | |
| 58 -- string data is always accessible as S (1 .. L). | |
| 59 | |
| 60 procedure Set_Wide_Wide_String | |
| 61 (UP : out Unbounded_Wide_Wide_String; | |
| 62 S : Wide_Wide_String) | |
| 63 renames Set_Unbounded_Wide_Wide_String; | |
| 64 -- This function sets the string contents of the referenced unbounded | |
| 65 -- string to the given string value. It is significantly more efficient | |
| 66 -- than the use of To_Unbounded_Wide_Wide_String with an assignment, since | |
| 67 -- it avoids the necessity of messing with finalization chains. The lower | |
| 68 -- bound of the string S is not required to be one. | |
| 69 | |
| 70 procedure Set_Wide_Wide_String | |
| 71 (UP : in out Unbounded_Wide_Wide_String; | |
| 72 S : Wide_Wide_String_Access); | |
| 73 pragma Inline (Set_Wide_Wide_String); | |
| 74 -- This version of Set_Wide_Wide_String takes a string access value, rather | |
| 75 -- than string. The lower bound of the string value is required to be one, | |
| 76 -- and this requirement is not checked. | |
