Custom Plug-ins for Master Index Custom Transaction Processing

You can add custom processing to the master index application by adding your own code to new Java classes in the EJB project for the master index application. These classes are called custom plug-ins. This ability allows you to tailor how messages are processed by the master index application. Plug-ins can be used to customize field validations, update policies, match processing logic, and record retrieval, and to create custom components for the master index application, such as custom phonetic encoders, block pickers, or query builders. You can create as many classes as you need to carry out the custom processes.

The following sections describe custom plug-ins that define custom processing. These are explained more fully in Understanding Sun Master Index Configuration Options .

• Master Index Update Policy Plug-ins - Define custom processing logic to perform against the resulting record of a transaction before it is stored in the database.

• Master Index Field Validation Plug-ins - Define validations to perform against specific fields, such as checking the local ID length and format.

• Master Index Field Masking Plug-ins - Define how the values for sensitive fields are hidden on the MIDM from users who do not have permission to view them.

• Master Index Match Processing Logic Plug-ins - Define custom logic based on predefined decision points for how records are matched during a transaction.

• Master Index Custom Plug-in Exception Processing - Define how exceptions are handled by the custom plug-ins you create.
