To Register the Comparators

1. Complete Step 1: Create the Custom Comparator Java Class.

2. In the same folder where you created the custom Java class package, create a new file named comparatorsList.xml.

   ---

   Tip –

   The comparators list file needs to be in the same working directory you created for the custom comparator Java classes.

   ---

3. Add the following header information to the file. You can copy this from the comparatorList.xml file in a master index application.

   <?xml version="1.0" encoding="UTF-8"?> <comparators-list xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="comparatorsList.xsd"> ... </comparators-list>

4. Define the following properties, using the XML structure described in Master Index Match Engine Comparator Definition List. Use the sample above as an example.

   • The group description and Java package for the group.

   • A description for each comparator.

   • The Java class name for each comparator or comparator subgroup.

   • The unique identifying name for each comparator.

   • A list of static parameters for each comparator or comparator subgroup (optional). If you define parameters, you must also perform the steps under Step 3: Define Parameter Validations (Optional).

   • A list of data sources for each comparator or comparator subgroup (optional). If you define data sources, you must also perform the steps under Step 4: Define Data Source Handling (Optional).

   • A list of dependency classes for each comparator or comparator subgroup (optional).

   • Whether to use curve adjustment for each comparator or comparator subgroup (optional). If you set curve adjustment to true, you must perform the steps under Step 5: Define Curve Adjustment or Linear Fitting (Optional).

5. Continue to Step 3: Define Parameter Validations (Optional)
