How to find which point belongs which cluster after running KMeansClusterer

[WangRamon]

Hi All I'm using KMeansClusterer, I will use KMeansDriver on a Hadoop 
environment later, but I think it will be easy to understand it by using 
KMeansClusterer, OK, so the question is i cannot find a way to find the cluster 
a point should belong to after running KMeansClusterer, I expect I can get some 
API on the Cluster interface to get all points/vector belong to this cluster, 
but... so did i miss something? Thanks a lot.  Cheers Ramon
