CharacterMap class

A CharacterMap class object contains a mapping of characters to characters. Each character in an In string (the “input table”) is associated with, or mapped to, an individual character from an Out string (the “output table”). The output table may be supplemented with instances of a pad character to ensure a one-to-one mapping with the input table characters.

List of CharacterMap methods lists all the methods in this class.

CharacterMap includes a constructor, copy methods, and an update method for modifying the map.

Example

Most of these methods are shown in the following example, which features the intrinsic String Translate function. In the example, a new CharacterMap is the argument for the Translate method; then that map is copied and modified, and the modified map is used in a second Translate call:

   begin
   %map is object characterMap
   %map2 is object characterMap
   %ls is longstring

   %map = New(in='x-', out='!c')
   %ls = 'xu--exx'
   printtext {~} = '{%ls:translate(%map)}'

   %map2 = %map:Copy
   %map2:Update(in='x',out='s')
   printtext {~} = '{%ls:translate(%map2)}'

   end

The result is:

    %ls:translate(%map) = '!ucce!!'
    %ls:translate(%map2) = 'success'

This class is new as of version 7.3 of the Sirius Mods.
