/**
|
|
* Interface for message attachments.
|
|
*
|
|
* Message attachments are optional bulk data objects that can be attached to a message, such as
|
|
* files or memory buffers. Transferring attachments within the same process is very efficient and
|
|
* amounts to copying a pointer to the data. On the other hand, sending message attachments to
|
|
* applications running in other processes or on other computers may - depending on their size -
|
|
* take a considerable amount of time, because they need to be serialized and transferred. For this
|
|
* reason, attachments are transferred separately from messages in such cases.
|
|
*
|
|
* NOTE: Message attachments are not fully implemented yet. In particular, transferring attachments
|
|
* over a network does not work yet. This API may change in the near future, so please use with care.
