TIdDecoder4to3 is a
TIdDecoder descendant that implements decoding capabilities for data encoded using
TIdEncoder3to4. TIdDecoder4to3 provides a decoding table to represent the valid characters in the encoder alphabet.
Note: TIdDecoder4to3 does not specify the valid characters in the decoding table. Application will generally use a descendant class, like TIdDeCoderMIME or
TIdDecoderUUE, where the alphabet is specified.
TIdDecoder4to3 provides methods to decode string values to as stream destination, and method to handle the low-level conversion performed when processing string input values.
