All Implemented Interfaces:

IProfileChangeJob

public class UninstallOperation
extends ProfileChangeOperation

An UninstallOperation describes an operation that uninstalls IInstallableUnits from a profile. The following snippet shows how one might use an UninstallOperation to perform a synchronous resolution and then kick off an uninstall in the background:

 UninstallOperation op = new UninstallOperation(session, new IInstallableUnit [] { removeThisIU });
 IStatus result = op.resolveModal(monitor);
 if (result.isOK()) {
   op.getProvisioningJob(monitor).schedule();
 }
