/* 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) (char *buf, int32 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.)
