The application employs a plugin architecture, allowing you to add new export formats without modifying existing code or addintional config. To add a new export format, simply create a new class implementing the Exportable interface and place it in the org.nmpl.exporters package.
Example for creating a new export format:
package org.nmpl.exporters;
import org.nmpl.Exportable;
public class NewFormatExporter implements Exportable {
// Implement the export method as per your requirements
}
You can give the name of the export format using annotaions like this:
package org.nmpl.exporters;
import org.nmpl.ExportType;
import org.nmpl.Exportable;
@ExportType("Export_Type_Name")
public class NewFormatExporter implements Exportable {
// Implement the export method as per your requirements
}
No changes to the existing code are needed. The new class is automatically recognized and integrated into the application at runtime.
The application is designed for configurationless operation due to its internal usage of Reflection and class loader libraries.
Go to the V0 directory and run the App.java inside itThe config.xml file, located in the resources directory, maps export formats to their corresponding Java class names. This enables the application to dynamically recognize and utilize new exporters without explicit configuration.
Example config.xml:
<exporters>
<exporter>
<type>html</type>
<class>org.nmpl.exporters.HTMLExporter</class>
</exporter>
<exporter>
<type>xml</type>
<class>org.nmpl.exporters.XMLExporter</class>
</exporter>
<exporter>
<type>newformat</type>
<class>org.nmpl.exporters.NewFormatExporter</class>
</exporter>
<!-- Add more exporter configurations as needed -->
</exporters>
