Class KeyedDataQueueDocument

java.lang.Object

com.ibm.as400.vaccess.KeyedDataQueueDocument

All Implemented Interfaces:

Serializable, Document

Deprecated.

Use Java Swing instead, along with the classes in package com.ibm.as400.access

public class KeyedDataQueueDocument
extends Object
implements Document, Serializable

The KeyedDataQueueDocument class represents an underlying model for text components, where the text is entries from a keyed data queue on a system.

Use this class in conjuction with any JTextComponent or any other component that works with the Document interface.

Most errors are reported as ErrorEvents rather than throwing exceptions. Users should listen for ErrorEvents in order to diagnose and recover from error conditions.

KeyedDataQueueDocument objects generate the following events:

• DataQueueEvent
• DocumentEvent
• ErrorEvent
• PropertyChangeEvent
• UndoableEditEvent
• WorkingEvent

The following example creates a document which contains the next entry in a data queue on a system. It then presents the document in a JTextField object.

// Set up the document and the JTextField.
AS400 system = new AS400 ("MySystem", "Userid", "Password");
KeyedDataQueueDocument document = new KeyedDataQueueDocument (system, "/QSYS.LIB/MYLIB.LIB/MYDATAQ.DTAQ");
JTextField textField = new JTextField (document, "", 50);


// Add the JTextField to a frame.
JFrame frame = new JFrame ("My Window");
frame.getContentPane().add(new JScrollPane(textField));




// Read the next entry from the data queue.
document.read (aKey);
