It demonstrates the -- use of these types and functions as they would be used in common -- programming practice. -- Character set creation, assignment, and comparison are evaluated -- in this test. Each of the functions provided in package -- Ada.Strings.Maps is utilized in creating or manipulating set objects, -- and the function results are evaluated for correctness. -- Character sequences are examined using the functions provided for -- manipulating objects of this type. Likewise, character maps are -- created, and their contents evaluated. Exception raising conditions -- from the function To_Mapping are also created. -- Note: Throughout this test, the set logical operators are printed in -- capital letters to enhance their visibility. -- -- -- CHANGE HISTORY: -- 06 Dec 94 SAIC ACVC 2.0 -- --! with Ada.Strings.Maps; with Report; procedure CXA4001 is use Ada.Strings; use type Maps.Character_Set; begin Report.Test ("CXA4001", "Check that the types, operations, and other " & "entities defined within the package " & "Ada.Strings.Maps are available and/or produce " & "correct results"); Test_Block: declare MidPoint_Letter : constant := 13; Last_Letter : constant := 26; Vowels : constant Maps.Character_Sequence := "aeiou"; Quasi_Vowel : constant Character := 'y'; Alphabet : Maps.Character_Sequence (1..Last_Letter); Half_Alphabet : Maps.Character_Sequence (1..MidPoint_Letter); Inverse_Alphabet : Maps.Character_Sequence (1..Last_Letter); Alphabet_Set, Consonant_Set, Vowel_Set, Full_Vowel_Set, First_Half_Set, Second_Half_Set : Maps.Character_Set; begin -- Load the alphabet string for use in creating sets. for i in 0..12 loop Half_Alphabet(i+1) := Character'Val(Character'Pos('a') + i); end loop; for i in 0..25 loop Alphabet(i+1) := Character'Val(Character'Pos('a') + i); end loop; -- Initialize a series of Character_Set objects.
