/* MimeLeaf is the class for the objects representing all MIME types which
are not containers for other MIME objects. The implication of this is
that they are MIME types which can have Content-Transfer-Encodings
applied to their data. This class provides that service in its
parse_buffer() method:
int (*parse_decoded_buffer) (const char *buf, int32_t size, MimeObject
*obj)
The `parse_buffer' method of MimeLeaf passes each block of data through
the appropriate decoder (if any) and then calls `parse_decoded_buffer'
on each block (not line) of output.
The default `parse_decoded_buffer' method of MimeLeaf line-buffers the
now-decoded data, handing each line to the `parse_line' method in turn.
If different behavior is desired (for example, if a class wants access
to the decoded data before it is line-buffered) the `parse_decoded_buffer'
method should be overridden. (MimeExternalObject does this.)
