public class TransformerRunner

extends java.lang.Object

This class is a generic launcher for Transformers.

The class that uses TransformerRunner must be a subclasses of Transformer, it must have a constructor that accepts only String parameters and it must call run() passing as parameters the full class name, the command line arguments and the names of the command line arguments that correspond to the constructor's parameters.

Usage Example:

    import com.devsphere.xml.saxdomix.SDXTransformer;

    import org.xml.sax.Attributes;
    import org.xml.sax.SAXException;

    import javax.xml.transform.TransformerException;
    import javax.xml.transform.stream.StreamSource;

    public class MyTransformer extends SDXTransformer {

        public MyTransformer(String xslSystemID)
                throws TransformerException {
            super(new StreamSource(xslSystemID));
        }

        public boolean wantDOM(String namespaceURI, String localName,
                String qualifiedName, Attributes attributes)
                throws SAXException {
            return ...
        }

        public static void main(String args[]) {
            TransformerRunner.run(MyTransformer.class.getName(),
                args, new String[] { "xsl" });
        }

    }

Command Line Syntax:

    java <className> -xsl <stylesheet> -in <input> [-out <output>]
    [-indent <amount>] [-method <method>] [-encoding <encoding>]
    [-omitdecl] [other application-specific parameters]

The run() method

• loads the class with the given name
• calls its constructor to create an instance
• uses the command line arguments to configure the created instance
• calls the transform() method of the created instance
