Restricting a specific user in a group from accessing task

[hguser]

Hi,

So the general requirement here is, I have user A who is in group 1. And for an approval user task I have added group 1. But i need to make sure that user A can't view /access this task.  I could only come across following methods, which will remove the named user or the entire group but couldnt find anything related to my use case. Can this be done?


deleteCandidateStarterGroup(String processDefinitionId, String groupId)
void   deleteCandidateStarterUser(String processDefinitionId, String userId)



Thanks,
hgUser

[hguser]

Oh i think the second method is what i need? the name was a bit misleading , hence the confusion.
