MIME::Decoder::Binary - perform no encoding/decoding

SYNOPSIS

Top

A generic decoder object; see MIME::Decoder for usage.

DESCRIPTION

Top

A MIME::Decoder subclass for the "binary" encoding (in other words, no encoding).

The "binary" decoder is a special case, since it's ill-advised to read the input line-by-line: after all, an uncompressed image file might conceivably have loooooooooong stretches of bytes without a "\n" among them, and we don't want to risk blowing out our core. So, we read-and-write fixed-size chunks.

Both the encoder and decoder do a simple pass-through of the data from input to output.
