    public class IMAPStore

extends Store
implements QuotaAwareStore, com.sun.mail.iap.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.

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 Summary
`static int` `RESPONSE` A special event type for a StoreEvent to indicate an IMAP response, if the mail.imap.enableimapevents property is set.

Method Detail

### protocolConnect

    protected boolean protocolConnect(String host,
                                      int pport,
                                      String user,
                                      String password)
                               throws MessagingException

  Implementation of protocolConnect(). Will create a connection to the server and authenticate the user using the mechanisms specified by various properties.

  The `host`, `user`, and `password` parameters must all be non-null. If the authentication mechanism being used does not require a password, an empty string or other suitable dummy password should be used.

  Overrides:
    `protocolConnect` in class `Service`
  Parameters:
    `host` - the name of the host to connect to
    `pport` - the port to use (-1 means use default port)
    `user` - the name of the user to login as
    `password` - the user's password
  Returns:
    true if connection successful, false if authentication failed
  Throws:
    `AuthenticationFailedException` - for authentication failures
    `MessagingException` - for non-authentication failures

### 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.

  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.

  Since:
    JavaMail 1.3.3

### hasCapability

    public boolean hasCapability(String capability)
                          throws MessagingException

  Throws:
    `MessagingException`
  Since:
    JavaMail 1.3.3

### isConnected

    public boolean isConnected()

  Check whether this store is connected. Override superclass method, to actually ping our server connection.

  Overrides:

  Throws:
    `Throwable`

### getDefaultFolder

    public Folder getDefaultFolder()
                            throws MessagingException

  Get named folder. Returns a new, closed IMAPFolder.

  Specified by:
    `getFolder` in class `Store`
  Parameters:

  Returns:
    Folder object
  Throws:
    `MessagingException`
  See Also:
    `Folder.exists()`, `Folder.create(int)`

### getFolder

    public Folder getFolder(URLName url)
                     throws MessagingException

  Get named folder. Returns a new, closed IMAPFolder.

  Specified by:
    `getFolder` in class `Store`
  Parameters:
    `url` - URLName that denotes a folder
  Returns:

  Throws:
    `MessagingException`
  See Also:
    `URLName`

### getPersonalNamespaces

    public Folder[] getPersonalNamespaces()
                                   throws MessagingException

  Using the IMAP NAMESPACE command (RFC 2342), return a set of folders representing the Personal namespaces.

  Overrides:
    `getPersonalNamespaces` in class `Store`
  Returns:
    array of Folder objects
  Throws:
    `MessagingException`

### getUserNamespaces

    public Folder[] getUserNamespaces(String user)

  Overrides:
    `getUserNamespaces` in class `Store`
  Returns:
    array of Folder objects
  Throws:
    `MessagingException`

### getSharedNamespaces

    public Folder[] getSharedNamespaces()
                                 throws MessagingException

    `MessagingException`

### 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(com.sun.mail.iap.Response r)

  Response handler method.

  Specified by:
    `handleResponse` in interface `com.sun.mail.iap.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 `ConnectionListener`s 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
