1.3.3. Custom Interceptors
Custom interceptors can be added to Red Hat JBoss Data Grid declaratively or programmatically. Custom interceptors extend JBoss Data Grid by allowing it to influence or respond to cache modifications. Examples of such cache modifications are the addition, removal or updating of elements or transactions.
1.3.3.1. Custom Interceptor Design
To design a custom interceptor in Red Hat JBoss Data Grid, adhere to the following guidelines:
- A custom interceptor must extend the
CommandInterceptor. - A custom interceptor must declare a public, empty constructor to allow for instantiation.
- A custom interceptor must have JavaBean style setters defined for any property that is defined through the
propertyelement.
