PartType is a read-only
TIdMessageCoderPartType property that represents the type detected for an RFC-822 compliant message part. PartType is used in
TIdMessageDecoder descendants, like
TIdMessageDecoderMIME,
TIdMessageDecoderUUE, and
TIdMessageDecoderUUE. PartType is updated when
ReadHeader is called to extract the RFC messaage headers in a message part. PartType is used in
ReadBody to determine the
TIdDecoder descendant that will be needed to process thte message part.
