POFile random access in J2ME
text
Body
copied!<p>does J2ME have something similar to <a href="http://download.oracle.com/javase/1.4.2/docs/api/java/io/RandomAccessFile.html" rel="nofollow"><code>RandomAccessFile</code></a> class, or is there any way to emulate this particular (random access) functionality?</p> <p>The problem is this: I have a rather large binary data file (~600 KB) and would like to create a mobile application for using that data. Format of that data is home-made and contains many index blocks and data blocks. Reading the data on other platforms (like PHP or C) usually goes like this:</p> <ol> <li>Read 2 bytes for index key (<code>K</code>), another 2 for index value (<code>V</code>) for the data type needed</li> <li>Skip <code>V</code> bytes from the start of the file to seek to a file position there the data for index key <code>K</code> starts</li> <li>Read the data</li> <li>Profit :)</li> </ol> <p>This happens many times during the program flow.</p> <p>Um, and I'm investigating possibility of doing the very same on J2ME, and while I admit I'm quite new to the whole Java thing, I can't seem to be able to find anything beyond <a href="http://java.sun.com/javame/reference/apis/jsr118/java/io/InputStream.html" rel="nofollow"><code>InputStream</code></a> (<a href="http://java.sun.com/javame/reference/apis/jsr118/java/io/DataInputStream.html" rel="nofollow"><code>DataInputStream</code></a>) classes which don't have the basic seeking/skipping to byte/returning position functions I need.</p> <p>So, what are my chances?</p>
