Usage

From source file:de.ingrid.interfaces.csw.tools.FileUtils.java

/**
 * This function will copy files or directories from one location to
 * another. note that the source and the destination must be mutually
 * exclusive. This function can not be used to copy a directory to a sub
 * directory of itself. The function will also have problems if the
 * destination files already exist./*from   www  .ja  v a 2 s  .com*/
 * 
 * @param src
 *            -- A File object that represents the source for the copy
 * @param dest
 *            -- A File object that represnts the destination for the copy.
 * @throws IOException
 *             if unable to copy.
