val make_c2i_table : ?default:int -> ?case_insensitive:bool -> string array -> c2i_table

Make conversion table of char -> int from a string array. For each string at position i of the array, each character of the string is associated with i. (The range of the conversion is limited from 0 to l-1 where l is the length of the array) Raises Invalid_argument if the same character corresponds to more than one value, or if any of the strings are empty. An optional default (default=-1) value can be specified for characters not appearing in the string array.

val make_i2c_table : string -> i2c_table

Make conversion table of int -> char from a string. For a given i, the ith character of the string is associated. (The domain of the conversion is limited from 0 to l-1 where l is the length of the string).

val make_bij_table : ?case_insensitive:bool -> string -> i2c_table * c2i_table

Make a table for the bijection (one-to-one correspondance) between each character of the string, and its position. Returns the pair of conversion tables for both ways.

val conv_c2i : c2i_table -> char -> int

Convert a character to integer using the conversion table.

val conv_i2c : i2c_table -> int -> char

Convert an integer to a character. Raises IntOutOfBounds if the integer does not correspond to any characters. If BC_Char.make_c2i_table was used, the first character of the string at position i of the array given to BC_Char.make_c2i_table is returned.
