      • toString

        public void toString​(java.io.Writer stream)
                      throws java.io.IOException
        Converts the active state into something meant for human consumption. The method will be called when recursively traversing the instance tree.
        Specified by:
        toString in class org.griphyn.vdl.Chimera
        Parameters:
        stream - is a stream opened and ready for writing. This can also be a string stream for efficient output.
        Throws:
        java.io.IOException - if something fishy happens to the stream.
      • toXML

        public void toXML​(java.io.Writer stream,
                          java.lang.String indent,
                          java.lang.String namespace)
                   throws java.io.IOException
        Dump the state of the current element as XML output. This function traverses all sibling classes as necessary, and converts the data into pretty-printed XML output. The stream interface should be able to handle large output efficiently.
        Specified by:
        toXML in class org.griphyn.vdl.Chimera
        Parameters:
        stream - is a stream opened and ready for writing. This can also be a string stream for efficient output.
        indent - is a String of spaces used for pretty printing. The initial amount of spaces should be an empty string. The parameter is used internally for the recursive traversal. If a null value is specified, no indentation nor linefeeds will be generated.
        namespace - is the XML schema namespace prefix. If neither empty nor null, each element will be prefixed with this prefix, and the root element will map the XML namespace.
        Throws:
        java.io.IOException - if something fishy happens to the stream.
