Field Detail

### DEFAULT_PORT

    public static final int DEFAULT_PORT

  The default IMAP port (RFC 3501).

    protected static final String __DEFAULT_ENCODING

  The default control socket ecoding.

  See Also:
    Constant Field Values

### __writer

    protected BufferedWriter __writer

### _reader

Constructor Detail

### IMAP

    public IMAP()

  The default IMAPClient constructor. Initializes the state to `DISCONNECTED_STATE`.

Method Detail

### _connectAction_

    protected void _connectAction_()
                            throws IOException

  Performs connection initialization and sets state to `IMAP.IMAPState.NOT_AUTH_STATE`.

  Overrides:
    `_connectAction_` in class `SocketClient`
  Throws:
    `IOException`

### setState

    protected void setState(IMAP.IMAPState state)

  Sets IMAP client state. This must be one of the `_STATE` constants.

  Parameters:
    `state` - The new state.

### getState

    public IMAP.IMAPState getState()

  Returns the current IMAP client state.

  Returns:
    The current IMAP client state.

### disconnect

    public void disconnect()
                    throws IOException

  Disconnects the client from the server, and sets the state to `DISCONNECTED_STATE` . The reply text information from the last issued command is voided to allow garbage collection of the memory used to store that information.
