Examples of com.xmultra.util.FileUtils

com.xmultra.util.FileUtils
FileUtils contains methods for accessing directories and files. All read, writes, or deletes are done through static synchronized methods or a synchronized block (synchronized on the FileUtils.class file--the same object that a static synchronized block synchronizes on). A static synchronized block is used when logging or other access to instance variables is done (not allowed in a static method).
The synchronization is done as a safety precaution so the underlying OS is not overloaded with too many simultaneous file i/o requests. Synchronization does not seem to significantly affect performance. @author Wayne W. Weber @version $Revision: #2 $ @since 1.2
