This constructor also must throw 0N/A * an IllegalArgumentException if it does not understand the 0N/A * <code>Configuration.Parameters</code> input. 0N/A * Retrieve the AppConfigurationEntries for the specified <i>name</i>. 0N/A * @param name the name used to index the Configuration. 0N/A * @return an array of AppConfigurationEntries for the specified 0N/A * <i>name</i>, or null if there are no entries. 0N/A * Refresh and reload the Configuration. 0N/A * contents in an implementation-dependent manner. 0N/A * For example, if this Configuration object stores its entries in a file, 0N/A * calling <code>refresh</code> may cause the file to be re-read. 0N/A * <p> The default implementation of this method does nothing. 0N/A * This method should be overridden if a refresh operation is supported 0N/A * by the implementation. 0N/A * @exception SecurityException if the caller does not have permission 0N/A * to refresh its Configuration.
