Class Store

java.lang.Object
javax.mail.Service
javax.mail.Store
All Implemented Interfaces:
AutoCloseable
Direct Known Subclasses:
IMAPStore, POP3Store
public abstract class Store extends Service
An abstract class that models a message store and its access protocol, for storing and retrieving messages. Subclasses provide actual implementations.

Note that Store extends the Service class, which provides many common methods for naming stores, connecting to stores, and listening to connection events.

  • Method Details

    • getDefaultFolder

      public abstract Folder getDefaultFolder() throws MessagingException
      Returns a Folder object that represents the 'root' of the default namespace presented to the user by the Store.
      Returns:
      the root Folder
      Throws:
      IllegalStateException - if this Store is not connected.
      MessagingException - for other failures

    • getFolder

      public abstract Folder getFolder(String name) throws MessagingException
      Return the Folder object corresponding to the given name. Note that a Folder object is returned even if the named folder does not physically exist on the Store. The exists() method on the folder object indicates whether this folder really exists.

      Folder objects are not cached by the Store, so invoking this method on the same name multiple times will return that many distinct Folder objects.

      Parameters:
      name - The name of the Folder. In some Stores, name can be an absolute path if it starts with the hierarchy delimiter. Else it is interpreted relative to the 'root' of this namespace.
      Returns:
      Folder object
      Throws:
      IllegalStateException - if this Store is not connected.
      MessagingException - for other failures

    • getFolder

      public abstract Folder getFolder(URLName url) throws MessagingException
      Return a closed Folder object, corresponding to the given URLName. The store specified in the given URLName should refer to this Store object.

      Implementations of this method may obtain the name of the actual folder using the getFile() method on URLName, and use that name to create the folder.

      Parameters:
      url - URLName that denotes a folder
      Returns:
      Folder object
      Throws:
      IllegalStateException - if this Store is not connected.
      MessagingException - for other failures

    • getPersonalNamespaces

      public Folder[] getPersonalNamespaces() throws MessagingException
      Return a set of folders representing the personal namespaces for the current user. A personal namespace is a set of names that is considered within the personal scope of the authenticated user. Typically, only the authenticated user has access to mail folders in their personal namespace. If an INBOX exists for a user, it must appear within the user's personal namespace. In the typical case, there should be only one personal namespace for each user in each Store.

      This implementation returns an array with a single entry containing the return value of the getDefaultFolder method. Subclasses should override this method to return appropriate information.

      Returns:
      array of Folder objects
      Throws:
      IllegalStateException - if this Store is not connected.
      MessagingException - for other failures

    • getUserNamespaces

      public Folder[] getUserNamespaces(String user) throws MessagingException
      Return a set of folders representing the namespaces for user. The namespaces returned represent the personal namespaces for the user. To access mail folders in the other user's namespace, the currently authenticated user must be explicitly granted access rights. For example, it is common for a manager to grant to their secretary access rights to their mail folders.

      This implementation returns an empty array. Subclasses should override this method to return appropriate information.

      Parameters:
      user - the user name
      Returns:
      array of Folder objects
      Throws:
      IllegalStateException - if this Store is not connected.
      MessagingException - for other failures
      Since:
      JavaMail 1.2

    • getSharedNamespaces

      public Folder[] getSharedNamespaces() throws MessagingException
      Return a set of folders representing the shared namespaces. A shared namespace is a namespace that consists of mail folders that are intended to be shared amongst users and do not exist within a user's personal namespace.

      This implementation returns an empty array. Subclasses should override this method to return appropriate information.

      Returns:
      array of Folder objects
      Throws:
      IllegalStateException - if this Store is not connected.
      MessagingException - for other failures

    • addStoreListener

      public void addStoreListener(StoreListener l)
      Add a listener for StoreEvents on this Store.

      The default implementation provided here adds this listener to an internal list of StoreListeners.

      Parameters:
      l - the Listener for Store events
      See Also:

    • removeStoreListener

      public void removeStoreListener(StoreListener l)
      Remove a listener for Store events.

      The default implementation provided here removes this listener from the internal list of StoreListeners.

      Parameters:
      l - the listener
      See Also:

    • addFolderListener

      public void addFolderListener(FolderListener l)
      Add a listener for Folder events on any Folder object obtained from this Store. FolderEvents are delivered to FolderListeners on the affected Folder as well as to FolderListeners on the containing Store.

      The default implementation provided here adds this listener to an internal list of FolderListeners.

      Parameters:
      l - the Listener for Folder events
      See Also:

    • removeFolderListener

      public void removeFolderListener(FolderListener l)
      Remove a listener for Folder events.

      The default implementation provided here removes this listener from the internal list of FolderListeners.

      Parameters:
      l - the listener
