IdMessageCoder

TIdMessageDecoder is a TIdComponent descendant that implements a decoder for RFC-2822 compliant message parts. 

TIdMessageDecoder provides properties and methods used to read and process RFC message headers and body lines from a TStream descendant. 

TIdMessageDecoder is a base class that establishes the framework for Indy message decoders. TIdMessageDecoder descendants, like TIdMessageDecoderMIME and TIdMessageDecoderUUE, further refine the message decoder framework by implementing support for encoding schemes for message parts. 

TIdMessageDecoder and descendant classes are used when TIdMessageClient (or a descendant like TIdIMAP4) needs to decode message parts during receipt of the body for a message.
