Usage

From source file:FileUtils.java

/**
 * /*from   www.ja  v a 2s .  c om*/
 * Merges the two paths to create a valid version of the second path. This
 * method should be used when you encounter a relative path in a document and
 * must resolve it based on the path of the current document. An example would
 * be: <br>
 * <br>
 * <b>original path</b> - files/customers/Orders.xml <br>
 * <br>
 * <b>relative path</b> - ../Accounts.xml <br>
 * <br>
 * <b>result</b> - files/customers/Accounts.xml <br>
 * <br>
 * The only time this method cannot be used is if the original path is for a
 * file that is in the root (has no directory as part of its path) and the
 * relative path starts with "..".
 * 
 * @param originalPath
 *          The path of the file that references another file.
 * 
 * @param relativePath
 *          The path of the other file, which is relative to the original.
 * 
 * @return A proper path for the other file, one that can be used to open and
 *         verify the file.
 *
