public class SplitAttachmentsExpression
extends org.apache.camel.support.ExpressionAdapter

A Expression which can be used to split a MailMessage per attachment. For example if a mail message has 5 attachments, then this expression will return a List<Message> that contains 5 Message. The message can be split 2 ways:

As an attachment	The message is split into cloned messages, each has only one attachment. The mail attachment in each message remains unprocessed.
As a byte[] or String	The attachments are split into new messages as the body. This allows the split messages to be easily used by other processors / routes, as many other camel components can work on the byte[] or String, e.g. it can be written to disk using camel-file.

In both cases the attachment name is written to a the camel header "CamelSplitAttachmentId"
