Package com.sun.mail.imap

Class IMAPStore

java.lang.Object
javax.mail.Service
javax.mail.Store
com.sun.mail.imap.IMAPStore
All Implemented Interfaces:
ResponseHandler, AutoCloseable, QuotaAwareStore
Direct Known Subclasses:
IMAPSSLStore
public class IMAPStore extends Store implements QuotaAwareStore, ResponseHandler
This class provides access to an IMAP message store.

Applications that need to make use of IMAP-specific features may cast a Store object to an IMAPStore 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 id method supports the IMAP ID extension; see RFC 2971. The fields ID_NAME, ID_VERSION, etc. represent the suggested field names in RFC 2971 section 3.3 and may be used as keys in the Map containing client values or server values.

See the com.sun.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.

  • Field Details

  • Constructor Details

    • IMAPStore

      public IMAPStore(Session session, URLName url)
      Constructor that takes a Session object and a URLName that represents a specific IMAP server.
      Parameters:
      session - the Session
      url - the URLName of this store

  • Method Details

    • isSSL

      public boolean isSSL()
      Does this IMAPStore use SSL when connecting to the server?
      Returns:
      true if using SSL
      Since:
      JavaMail 1.4.6

    • setUsername

      public void setUsername(String user)
      Set the user name that will be used for subsequent connections after this Store is first connected (for example, when creating a connection to open a Folder). This value is overridden by any call to the Store's connect method.

      Some IMAP servers may provide an authentication ID that can be used for more efficient authentication for future connections. This authentication ID is provided in a server-specific manner not described here.

      Most applications will never need to use this method.

      Parameters:
      user - the user name for the store
      Since:
      JavaMail 1.3.3

    • setPassword

      public void setPassword(String password)
      Set the password that will be used for subsequent connections after this Store is first connected (for example, when creating a connection to open a Folder). This value is overridden by any call to the Store's connect method.

      Most applications will never need to use this method.

      Parameters:
      password - the password for the store
      Since:
      JavaMail 1.3.3

    • hasCapability

    • getQuota

      public Quota[] getQuota(String root) throws MessagingException
      Get the quotas for the named quota root. Quotas are controlled on the basis of a quota root, not (necessarily) a folder. The relationship between folders and quota roots depends on the IMAP server. Some servers might implement a single quota root for all folders owned by a user. Other servers might implement a separate quota root for each folder. A single folder can even have multiple quota roots, perhaps controlling quotas for different resources.
      Specified by:
      getQuota in interface QuotaAwareStore
      Parameters:
      root - the name of the quota root
      Returns:
      array of Quota objects
      Throws:
      MessagingException - if the server doesn't support the QUOTA extension

    • setQuota

      public void setQuota(Quota quota) throws MessagingException
      Set the quotas for the quota root specified in the quota argument. Typically this will be one of the quota roots obtained from the getQuota method, but it need not be.
      Specified by:
      setQuota in interface QuotaAwareStore
      Parameters:
      quota - the quota to set
      Throws:
      MessagingException - if the server doesn't support the QUOTA extension

    • handleResponse

      public void handleResponse(Response r)
      Response handler method.
      Specified by:
      handleResponse in interface ResponseHandler

    • idle

      public void idle() throws 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 without the need for the client to constantly poll the server. Use a ConnectionListener to be notified of events. When another thread (e.g., the listener thread) needs to issue an IMAP comand for this Store, the idle mode will be terminated and this method will return. Typically the caller will invoke this method in a loop.

      If the mail.imap.enableimapevents property is set, notifications received while the IDLE command is active will be delivered to ConnectionListeners as events with a type of IMAPStore.RESPONSE. The event's message will be the raw IMAP response string. Note that most IMAP servers will not deliver any events when using the IDLE command on a connection with no mailbox selected (i.e., this method). In most cases you'll want to use the idle method on IMAPFolder.

      NOTE: This capability is highly experimental and likely will change in future releases.

      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:
      MessagingException - if the server doesn't support the IDLE extension
      IllegalStateException - if the store isn't connected
      Since:
      JavaMail 1.4.1

    • id

      public Map<String,String> id(Map<String,String> clientParams) throws 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:
      MessagingException - if the server doesn't support the ID extension
      Since:
      JavaMail 1.5.1
