Step 5: Define Curve Adjustment or Linear Fitting (Optional)

If your custom comparators use curve adjustment or linear fitting to adjust matching weight calculations, you need to create a Java class that defines the curve. You do not need to create this file in the same package as the Java comparator class, but for packaging purposes, create it in the same working folder.

You need to perform this step if you defined the following line in comparatorsList.xml for the comparator:

<curve-adjust status="true" />

To Define Curve Adjustment or Linear Fitting

1. Complete Step 4: Define Data Source Handling (Optional).

2. Create a Java class named the same name as the Java class that defines the comparator with “CurveAdjustor” appended.

   For example, if the comparator is defined by a class named ExactComparator, the parameter validation class would be ExactComparatorCurveAdjustor.

3. In this class, implement com.sun.mdm.matcher.configurator.CurveAdjustor.

   The method in this class is described below.

4. Continue to Step 6: Compile and Package the Comparator.
