capturing onAlterTable event

Hello

I have a requirement to capture the onAlterTable() event of hive metastore. 
I intend to do some data processing stuff if any of the column has been altered (ADD/DROP etc.).
Can someone please help me   find what has changed  in the 'alter table' operation?

I have this code
 
public void onAlterTable(AlterTableEvent ate) throws MetaException {
Table oldTable = ate.getOldTable();
Table newTable = ate.getNewTable(); 
                // Now what???
}


thanks
Santhoma
