<div class="section"><p>The DataQueue class in the micro package (<a href="javadoc/com/ibm/as400/micro/DataQueue.html#NAVBAR_TOP">com.ibm.as400.micro.DataQueue</a>) provides a modified subset
|
||
|
|
of the functions available in the <a href="dtaq.htm#dtaq">DataQueue class
|
||
|
|
in the access package</a> (com.ibm.as400.access.DataQueue). Use the DataQueue
|
||
|
|
class to have your <a href="microconcept.htm#microconcept__tier0">Tier0
|
||
|
|
device</a> read from or write to a data queue on the iSeries™ server.</p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> To
|
||
|
|
use ToolboxMe for iSeries classes, you must separately <a href="microsetup.htm#microsetup">download
|
||
|
|
and set up the ToolboxME for iSeries component</a>.</div>
|
||
|
|
<p>The DataQueue
|
||
|
|
class includes the following methods:</p>
|
||
|
|
<ul><li><a href="javadoc/com/ibm/as400/micro/DataQueue.html#READSTRING(COM.IBM.AS400.MICRO.AS400, JAVA.LANG.STRING)">Read</a> or <a href="javadoc/com/ibm/as400/micro/DataQueue.html#WRITE(COM.IBM.AS400.MICRO.AS400, JAVA.LANG.STRING, JAVA.LANG.STRING)">write</a> an entry as a String</li>
|
||
|
|
<li><a href="javadoc/com/ibm/as400/micro/DataQueue.html#READBYTES(COM.IBM.AS400.MICRO.AS400, JAVA.LANG.STRING)">Read</a> or <a href="javadoc/com/ibm/as400/micro/DataQueue.html#WRITE(COM.IBM.AS400.MICRO.AS400, JAVA.LANG.STRING, BYTE[])">write</a> an entry as an array of bytes</li>
|
||
|
|
</ul>
|
||
|
|
<p>To read or write entries, you need to supply the name of the iSeries server
|
||
|
|
where the data queue resides and the fully qualified integrated file system
|
||
|
|
path name of the data queue. When no entries are available, reading an entry
|
||
|
|
returns a null value.</p>
