Security Security Interceptor

Hazelcast IMDG Enterprise

Hazelcast allows you to intercept every remote operation executed by the client. This lets you add a very flexible custom security logic. To do this, implement com.hazelcast.security.SecurityInterceptor.

public class MySecurityInterceptor implements SecurityInterceptor {

  public void before( Credentials credentials, String serviceName,
                      String methodName, Parameters parameters )
      throws AccessControlException {
    // credentials: client credentials 
    // serviceName: MapService.SERVICE_NAME, QueueService.SERVICE_NAME, ... etc
    // methodName: put, get, offer, poll, ... etc
    // parameters: holds parameters of the executed method, iterable.
  }

  public void after( Credentials credentials, String serviceName,
                     String methodName, Parameters parameters ) {
    // can be used for logging etc.
  }
}

The before method will be called before processing the request on the remote server. The after method will be called after the processing. Exceptions thrown while executing the before method will propagate to the client, but exceptions thrown while executing the after method will be suppressed.
