Adding FileUtils.byteCountToDisplaySize(long size, boolean useSiUnits)
----------------------------------------------------------------------
Key: IO-294
URL: https://issues.apache.org/jira/browse/IO-294
Project: Commons IO
Issue Type: New Feature
Components: Utilities
Affects Versions: 2.1
Reporter: Jean-Noel Rouvignac
Fix For: 2.2
Attachments: FileUtils.java, FileUtilsTest.java
I have written a little Utility method that might benefit Commons IO:
{code}
public class FileUtils {
/**
* Returns a human-readable version of the file size (original is in
bytes). The implementation has the following features:
* <ul>
* <li>Supports the SI or IEC units.</li>
* <li>Supports I18n</li>
* <li>Display a one digit remainder (rounded down if less than 5, rounded
up otherwise)</li>
* <li>Once the main unit is >= 100, drops the remainder which would be
over precision.</li>
* </ul>
*
* @param size The number of bytes.
* @param useSiUnits if false, uses the IEC (International Electrotechnical
Commission) units (powers of 2), else uses SI (International System of Units)
* units (powers of 10).
* @return A human-readable display value (includes units).
*/
public static String byteCountToDisplaySize(long size, boolean useSiUnits) {
{code}
