Class IMAPFolder

  • All Implemented Interfaces:
    jakarta.mail.UIDFolder, java.lang.AutoCloseable, ResponseHandler
    Direct Known Subclasses:
    DefaultFolder
    public class IMAPFolder
extends jakarta.mail.Folder
implements jakarta.mail.UIDFolder, ResponseHandler
    This class implements an IMAP folder.

    A closed IMAPFolder object shares a protocol connection with its IMAPStore object. When the folder is opened, it gets its own protocol connection.

    Applications that need to make use of IMAP-specific features may cast a Folder object to an IMAPFolder object and use the methods on this class.

    The getQuota and setQuota methods support the IMAP QUOTA extension. Refer to RFC 2087 for more information.

    The getACL, addACL, removeACL, addRights, removeRights, listRights, and myRights methods support the IMAP ACL extension. Refer to RFC 2086 for more information.

    The getSortedMessages methods support the IMAP SORT extension. Refer to RFC 5256 for more information.

    The open(int,ResyncData) method and ResyncData class supports the IMAP CONDSTORE and QRESYNC extensions. Refer to RFC 4551 and RFC 5162 for more information.

    The doCommand method and IMAPFolder.ProtocolCommand interface support use of arbitrary IMAP protocol commands.

    See the org.eclipse.angus.mail.imap package documentation for further information on the IMAP protocol provider.

    WARNING: The APIs unique to this class should be considered EXPERIMENTAL. They may be changed in the future in ways that are incompatible with applications using the current APIs.

        Get the quotas for the quotaroot associated with this folder. Note that many folders may have the same quotaroot. Quotas are controlled on the basis of a quotaroot, not (necessarily) a folder. The relationship between folders and quotaroots depends on the IMAP server. Some servers might implement a single quotaroot for all folders owned by a user. Other servers might implement a separate quotaroot for each folder. A single folder can even have multiple quotaroots, perhaps controlling quotas for different resources.
        Returns:

      • idle

        public void idle()
          throws jakarta.mail.MessagingException
        Use the IMAP IDLE command (see RFC 2177), if supported by the server, to enter idle mode so that the server can send unsolicited notifications of new messages arriving, etc. without the need for the client to constantly poll the server. Use an appropriate listener to be notified of new messages or other events. When another thread (e.g., the listener thread) needs to issue an IMAP comand for this folder, the idle mode will be terminated and this method will return. Typically the caller will invoke this method in a loop.

        The mail.imap.minidletime property enforces a minimum delay before returning from this method, to ensure that other threads have a chance to issue commands before the caller invokes this method again. The default delay is 10 milliseconds.

        Throws:
        jakarta.mail.MessagingException - if the server doesn't support the IDLE extension
        java.lang.IllegalStateException - if the folder isn't open
        Since:
        JavaMail 1.4.1

      • idle

        public void idle​(boolean once)
          throws jakarta.mail.MessagingException
        Like idle(), but if once is true, abort the IDLE command after the first notification, to allow the caller to process any notification synchronously.
        Parameters:
        once - only do one notification?
        Throws:
        jakarta.mail.MessagingException - if the server doesn't support the IDLE extension
        java.lang.IllegalStateException - if the folder isn't open
        Since:
        JavaMail 1.4.3

      • id

        public java.util.Map<java.lang.String,​java.lang.String> id​(java.util.Map<java.lang.String,​java.lang.String> clientParams)
                                                          throws jakarta.mail.MessagingException
        Send the IMAP ID command (if supported by the server) and return the result from the server. The ID command identfies the client to the server and returns information about the server to the client. See RFC 2971. The returned Map is unmodifiable.
        Parameters:
        clientParams - a Map of keys and values identifying the client
        Returns:
        a Map of keys and values identifying the server
        Throws:
        jakarta.mail.MessagingException - if the server doesn't support the ID extension
        Since:
        JavaMail 1.5.1

      • getStatusItem

        public long getStatusItem​(java.lang.String item)
                   throws jakarta.mail.MessagingException
        Use the IMAP STATUS command to get the indicated item. The STATUS item may be a standard item such as "RECENT" or "UNSEEN", or may be a server-specific item. The folder must be closed. If the item is not found, or the folder is open, -1 is returned.
        Parameters:
        item - the STATUS item to fetch
        Returns:
        the value of the STATUS item, or -1
        Throws:
        jakarta.mail.MessagingException - for errors
        Since:
        JavaMail 1.5.2

      • handleResponse

        public void handleResponse​(Response r)
        The response handler. This is the callback routine that is invoked by the protocol layer.
        Specified by:
        handleResponse in interface ResponseHandler

      • getStoreProtocol

        protected IMAPProtocol getStoreProtocol()
                                 throws ProtocolException
        Get this folder's Store's protocol connection. When acquiring a store protocol object, it is important to use the following steps: 
             IMAPProtocol p = null;
     try {
         p = getStoreProtocol();
         // perform the command
     } catch (WhateverException ex) {
         // handle it
     } finally {
         releaseStoreProtocol(p);
     }
        ASSERT: Must be called with this folder's synchronization lock held.
        Returns:
        the IMAPProtocol for the Store's connection
        Throws:
        ProtocolException - for protocol errors

      • throwClosedException

        protected void throwClosedException​(ConnectionException cex)
                             throws jakarta.mail.FolderClosedException,
                                    jakarta.mail.StoreClosedException
        Throw the appropriate 'closed' exception.
        Parameters:
        cex - the ConnectionException
        Throws:
        jakarta.mail.FolderClosedException - if the folder is closed
        jakarta.mail.StoreClosedException - if the store is closed

      • getProtocol

        protected IMAPProtocol getProtocol()
                            throws ProtocolException
        Return the IMAPProtocol object for this folder.

        This method will block if necessary to wait for an IDLE command to finish.

        Returns:
        the IMAPProtocol object used when the folder is open
        Throws:
        ProtocolException - for protocol errors

      • doCommand

        public java.lang.Object doCommand​(IMAPFolder.ProtocolCommand cmd)
                           throws jakarta.mail.MessagingException
        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 org.eclipse.angus.mail.iap and org.eclipse.angus.mail.imap.protocol packages, best acquired by reading the source code. 

         import org.eclipse.angus.mail.iap.*;
 import org.eclipse.angus.mail.imap.*;
 import org.eclipse.angus.mail.imap.protocol.*;

 ...

 IMAPFolder f = (IMAPFolder)folder;
 Object val = f.doCommand(new IMAPFolder.ProtocolCommand() {
        public Object doCommand(IMAPProtocol p)
                        throws ProtocolException {
            p.simpleCommand("NOOP", null);
            return null;
    }
 });

        Here's a more complex example showing how to use the proposed IMAP SORT extension: 

         import org.eclipse.angus.mail.iap.*;
 import org.eclipse.angus.mail.imap.*;
 import org.eclipse.angus.mail.imap.protocol.*;

 ...

 IMAPFolder f = (IMAPFolder)folder;
 Object val = f.doCommand(new IMAPFolder.ProtocolCommand() {
        public Object doCommand(IMAPProtocol p)
                        throws ProtocolException {
            // Issue command
            Argument args = new Argument();
            Argument list = new Argument();
            list.writeString("SUBJECT");
            args.writeArgument(list);
            args.writeString("UTF-8");
            args.writeString("ALL");
            Response[] r = p.command("SORT", args);
            Response response = r[r.length-1];

            // Grab response
            Vector v = new Vector();
            if (response.isOK()) { // command succesful
                for (int i = 0, len = r.length; i < len; i++) {
                    if (!(r[i] instanceof IMAPResponse))
                        continue;

                    IMAPResponse ir = (IMAPResponse)r[i];
                    if (ir.keyEquals("SORT")) {
                        String num;
                        while ((num = ir.readAtomString()) != null)
                            System.out.println(num);
                        r[i] = null;
            }
        }
        }

            // dispatch remaining untagged responses
            p.notifyResponseHandlers(r);
            p.handleResult(response);

            return null;
    }
 });

        cmd - the protocol command
        Returns:
        the result of the command
