TIdDecoder4to3
Implements a decoder using a table-driven alphabet to produce output represented in the US-ASCII character set.

TIdDecoder4to3 = class(TIdDecoder)
Description
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.
