Prototype

public void flush() 

Source Link

Document

This method writes out the preamble associated with the XML encoding if it has not been written already and then writes out all of the values that been written to the stream since the last time flush was called.

Usage

From source file:Main.java

/**
 * Serializes an object into an xml file
 * /*from   w w  w.j  a va2s.  c  om*/
 * @param object object to serialize
 * @param fileName path to file
 */
public static void encodeToFile(Object object, String fileName) throws FileNotFoundException, IOException {
    XMLEncoder encoder = new XMLEncoder(new FileOutputStream(fileName));
    try {
        encoder.writeObject(object);
        encoder.flush();
    } finally {
        encoder.close();
    }
}
