Class IMAPStore

java.lang.Object
  javax.mail.Service
      javax.mail.Store
          com.sun.mail.imap.IMAPStore

All Implemented Interfaces:

com.sun.mail.iap.ResponseHandler, QuotaAwareStore

Direct Known Subclasses:

IMAPSSLStore

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.

Constructor Detail

IMAPStore

public IMAPStore(Session session,
                 URLName url)

Constructor that takes a Session object and a URLName that represents a specific IMAP server.

IMAPStore

protected IMAPStore(Session session,
                    URLName url,
                    java.lang.String name,
                    int defaultPort,
                    boolean isSSL)

Constructor used by this class and by IMAPSSLStore subclass.

Method Detail

protocolConnect

protected boolean protocolConnect(java.lang.String host,
                                  int pport,
                                  java.lang.String user,
                                  java.lang.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(java.lang.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(java.lang.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(java.lang.String capability)
                      throws MessagingException

Return true if the specified capability string is in the list of capabilities the server announced.

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:

isConnected in class Service

Returns:

true if the service is connected, false if it is not connected

close

public void close()
           throws MessagingException

Close this Store.

Overrides:

close in class Service

Throws:

MessagingException - for errors while closing

Throws:

java.lang.Throwable

getDefaultFolder

public Folder getDefaultFolder()
                        throws MessagingException

the root Folder

Throws:

MessagingException

getFolder

public Folder getFolder(java.lang.String name)
                 throws MessagingException

Get named folder. Returns a new, closed IMAPFolder.

Specified by:

Returns:

Folder object

Throws:

See Also:

Folder.exists(), Folder.create(int)

getFolder

public Folder getFolder(URLName url)
                 throws MessagingException

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(java.lang.String user)

getQuota

public Quota[] getQuota(java.lang.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
