<h1 class="topictitle1">IFSFileOutputStream class</h1>
|
||
|
|
<div><p>The IFSFileOutputStream class represents an output stream for writing
|
||
|
|
data to a file on the server.</p>
|
||
|
|
<div class="section"><p><a href="javadoc/com/ibm/as400/access/IFSFileOutputStream.html#NAVBAR_TOP"> IFSFileOutputStream</a> </p>
|
||
|
|
<p>As in the IFSFile class,
|
||
|
|
methods exist in IFSFileOutputStream that duplicate the methods in FileOutputStream
|
||
|
|
from the java.io package. IFSFileOutputStream also has additional methods
|
||
|
|
specific to the server. The IFSFileOutputStream class allows a Java™ program
|
||
|
|
to do the following:</p>
|
||
|
|
<ul><li><a href="javadoc/com/ibm/as400/access/IFSFileOutputStream.html#CONSTRUCTOR_DETAIL"> Open</a> a file for writing. If the file already exists,
|
||
|
|
it is replaced. Constructors are available that specify the file sharing mode
|
||
|
|
and whether the contents of an existing file have been appended.</li>
|
||
|
|
<li><a href="javadoc/com/ibm/as400/access/IFSFileOutputStream.html#WRITE(INT)"> Write</a> bytes to the stream.</li>
|
||
|
|
<li><a href="javadoc/com/ibm/as400/access/IFSFileOutputStream.html#FLUSH()"> Commit</a> to disk the bytes that are written to the stream.</li>
|
||
|
|
<li><a href="javadoc/com/ibm/as400/access/IFSFileOutputStream.html#LOCK(INT)"> Lock</a> or <a href="javadoc/com/ibm/as400/access/IFSFileOutputStream.html#UNLOCK(COM.IBM.AS400.ACCESS.IFSKEY)"> unlock</a> bytes in the stream.</li>
|
||
|
|
<li><a href="javadoc/com/ibm/as400/access/IFSFileOutputStream.html#CLOSE()"> Close</a> the file.</li>
|
||
|
|
</ul>
|
||
|
|
<p>As in FileOutputStream in java.io, this class allows a Java program
|
||
|
|
to sequentially write a stream of bytes to the file.</p>
|
||
|
|
<p>In addition to
|
||
|
|
the methods in FileOutputStream, IFSFileOutputStream gives the Java program
|
||
|
|
the following options:</p>
|
||
|
|
<ul><li>Locking and unlocking bytes in the stream. See <a href="ifskey.htm#ifskey">IFSKey</a> for
|
||
|
|
more information.</li>
|
||
|
|
<li>Specifying a sharing mode when the file is opened. See <a href="ifsmode.htm#ifsmode">sharing
|
||
|
|
modes</a> for more information.</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Example: Using IFSFileOutputStream</h4><p>The following
|
||
|
|
example shows how to use the IFSFileOutputStream class:</p>
|
||
|
|
<pre> // Create an AS400 object
|
||
|
|
AS400 sys = new AS400("mySystem.myCompany.com");
|
||
|
|
|
||
|
|
// Open a file object that
|
||
|
|
// represents the file.
|
||
|
|
IFSFileOutputStream aFile = new IFSFileOutputStream(sys,"/mydir1/mydir2/myfile");
|
||
|
|
|
||
|
|
// Write to the file
|
||
|
|
byte i = 123;
|
||
|
|
aFile.write(i);
|
||
|
|
|
||
|
|
// Close the file.
|
||
|
|
aFile.close();</pre>
