To Define Parameter Validations

1. Complete Step 2: Register the Comparator in the Comparators List.

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

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

3. In this class, implement com.sun.mdm.matcher.comparators.validator.ParametersValidator.

   The method contained in this class is described below.

4. Continue to Step 4: Define Data Source Handling (Optional).
