| Methods Summary |
|---|
| public void | addACL(com.sun.mail.imap.ACL acl)Add an access control list entry to the access control list
for this folder.

Return array of Message objects representing

that the folder must be open.
Each element of the returned array corresponds to
an element of the msgs array. A null
element means the server didn't return UID information
for the appended message.
Depends on the APPENDUID response code defined by the
UIDPLUS extension -
RFC 2359.

| public java.lang.Object | doCommand(com.sun.mail.imap.IMAPFolder$ProtocolCommand cmd)Execute a user-supplied IMAP command. The command is executed
in the appropriate context with the necessary locks held and
using the appropriate IMAPProtocol object.
This method returns whatever the ProtocolCommand
object's doCommand method returns. If the
doCommand method throws a ConnectionException
it is translated into a StoreClosedException or
FolderClosedException as appropriate. If the
doCommand method throws a ProtocolException
it is translated into a MessagingException.
The following example shows how to execute the IMAP NOOP command.
Executing more complex IMAP commands requires intimate knowledge
of the com.sun.mail.iap and
com.sun.mail.imap.protocol packages, best acquired by
reading the source code.
