Usage

From source file:net.longfalcon.newsj.nntp.client.CustomNNTPClient.java

/***
 * Post an article to the NNTP server.  This method returns a
 * DotTerminatedMessageWriter instance to which the article can be
 * written.  Null is returned if the posting attempt fails.  You
 * should check {@link NNTP#isAllowedToPost isAllowedToPost() }
 *  before trying to post.  However, a posting
 * attempt can fail due to malformed headers.
 * <p>/* www  .j  a va 2 s .c om*/
 * You must not issue any commands to the NNTP server (i.e., call any
 * (other methods) until you finish writing to the returned Writer
 * instance and close it.  The NNTP protocol uses the same stream for
 * issuing commands as it does for returning results.  Therefore the
 * returned Writer actually writes directly to the NNTP connection.
 * After you close the writer, you can execute new commands.  If you
 * do not follow these requirements your program will not work properly.
 * <p>
 * Different NNTP servers will require different header formats, but
 * you can use the provided
 * {@link org.apache.commons.net.nntp.SimpleNNTPHeader}
 * class to construct the bare minimum acceptable header for most
 * news readers.  To construct more complicated headers you should
 * refer to RFC 822.  When the Java Mail API is finalized, you will be
 * able to use it to compose fully compliant Internet text messages.
 * The DotTerminatedMessageWriter takes care of doubling line-leading
 * dots and ending the message with a single dot upon closing, so all
 * you have to worry about is writing the header and the message.
 * <p>
 * Upon closing the returned Writer, you need to call
 * {@link #completePendingCommand  completePendingCommand() }
 * to finalize the posting and verify its success or failure from
 * the server reply.
 * <p>
 * @return A DotTerminatedMessageWriter to which the article (including
 *      header) can be written.  Returns null if the command fails.
 * @exception IOException  If an I/O error occurs while either sending a
 *      command to the server or receiving a reply from the server.
