Subject [jira] Created: (HBASE-3348) Allow Observers to completely override base function
Date Mon, 13 Dec 2010 23:00:06 GMT
Allow Observers to completely override base function

                 Key: HBASE-3348
                 URL: https://issues.apache.org/jira/browse/HBASE-3348
             Project: HBase
          Issue Type: Sub-task
            Reporter: Andrew Purtell
             Fix For: 0.92.0

Currently an observer can act as a filter or translator but cannot stop a subsequent call
down to the base method for get, put, delete, etc. This means an observer cannot completely
override the base function. To deal with this we can:

- Change the preXXX methods to return the same type as the postXXX methods, the same return
type of the base method. 

- Extend {{Coprocessor.Environment}} with methods that get/set a "should continue" flag.
