Creating Your Own DPL

Creating your own DPL requires JAVAJava programming skills and a familiarity with the DPL interface definition. It involves a two-step process: First,first, you need to implement the DPL main class; second, you need to define a new DPL type for Appvance IQ.

The DPL JAVAJava class implements the standard DPL methods including getNextDatagetNextData, , getDataByIndex ,getDataByIndex, and more. It needs to implement the com.Appvance.tool.dpl.DataProduction interface. Here is an example:

import com.Appvance.tool.dpl.DataProduction;
public class SimpleDPL implements DataProduction{DataProduction {
public SimpleDPL() { }
public void setup(String data) {
System.out.println("This is a setup using data "+data);
}
public Object getData() { return null; }
public Object getRandomData() { return "RANDOM DATA"; }
public Object getNextData() { return "Simple data: getNextData"; }
public Object getDataByIndex(int index) {
return "Simple data: get data by index "+index;
}
public void tearDown() { }
}

Once you define and compile a custom DPL packaged into a .jar file, you should use the <DataSources> in a TScenario document to identify your new DPL type.
