public class ImapMailReceiver
extends AbstractMailReceiver

A MailReceiver implementation for receiving mail messages from a mail server that supports the IMAP protocol. In addition to the pollable AbstractMailReceiver.receive() method, the waitForNewMessages() method provides the option of blocking until new messages are available prior to calling AbstractMailReceiver.receive(). That option is only available if the server supports the idle command.

Method Detail

isShouldMarkMessagesAsRead

public Boolean isShouldMarkMessagesAsRead()

Check if messages should be marked as read.

Returns:

true if messages should be marked as read.

setSearchTermStrategy

public void setSearchTermStrategy(SearchTermStrategy searchTermStrategy)

Provides a way to set custom SearchTermStrategy to compile a SearchTerm to be applied when retrieving mail

Parameters:

searchTermStrategy - The search term strategy implementation.

setShouldMarkMessagesAsRead

public void setShouldMarkMessagesAsRead(Boolean shouldMarkMessagesAsRead)

Specify if messages should be marked as read.

Parameters:

shouldMarkMessagesAsRead - true if messages should be marked as read.

setCancelIdleInterval

public void setCancelIdleInterval(long cancelIdleInterval)

IDLE commands will be terminated after this interval; useful in cases where a connection might be silently dropped. A new IDLE will usually immediately be processed. Specified in seconds; default 120 (2 minutes). RFC 2177 recommends an interval no larger than 29 minutes.

Parameters:

cancelIdleInterval - the cancelIdleInterval to set

Since:

3.0.5

onInit

protected void onInit()
               throws Exception

Description copied from class: IntegrationObjectSupport

Subclasses may implement this for initialization logic.

Overrides:

onInit in class AbstractMailReceiver

Throws:

Exception - Any exception.

waitForNewMessages

public void waitForNewMessages()
                        throws MessagingException

This method is unique to the IMAP receiver and only works if IMAP IDLE is supported (see RFC 2177 for more detail).

Throws:

MessagingException - Any MessagingException.

searchForNewMessages

protected Message[] searchForNewMessages()
                                  throws MessagingException

Retrieves new messages from this receiver's folder. This implementation creates a SearchTerm that searches for all messages in the folder that are RECENT, not ANSWERED, and not DELETED. The search term is used to search for new messages.

Specified by:

searchForNewMessages in class AbstractMailReceiver

Returns:

the new messages

Throws:

MessagingException - in case of JavaMail errors

setAdditionalFlags

protected void setAdditionalFlags(Message message)
                           throws MessagingException

Description copied from class: AbstractMailReceiver

Optional method allowing you to set additional flags. Currently only implemented in IMapMailReceiver.

Overrides:

setAdditionalFlags in class AbstractMailReceiver

Parameters:

message - The message.

Throws:

MessagingException - A MessagingException.
