How to access the method delete_active_connection(iControl.jar) using java ???

I couldn't find the System: Connections Interface implementation in iControl jar.

 

I can find all other implementations under System module such as: getSystemCertificateRevocationListFile() getSystemCluster() getSystemConfigSync() getSystemDisk() etc.,

 

I couldn't find something like getSystemConnections(). Is that been implemented in any other name?
