Listener/Writer events for Region.get() operation

[Nilkanth Patel]

Hello,

Is it possible to get beforeGet(), afterGet() events for Region.get() API
with current state of codebase..?

Seeing the internal code, it seems *i need to add code *(that invoke
listener, writer callbacks) for these events, something similar to the way
events for Region.put() are invoked. is this a correct understanding..?

If so, I need to create a EntryEventImpl (shown in Red colour ) and pass
it. What is the purpose of clientEvent here ? can i use clientEvent directly
to create Get events or is it used for some different purpose?

*LocalRegion.java*

 @Override
  public Object get(Object key, Object aCallbackArgument,
      boolean generateCallbacks, EntryEventImpl clientEvent) throws
TimeoutException, CacheLoaderException
  {
    *clientEvent = newGetEntryEvent(key, aCallbackArgument);*
    Object result = get(key, aCallbackArgument, generateCallbacks,
false, false, null, *clientEvent*, false, true/*allowReadFromHDFS*/);
    if (Token.isInvalid(result)) {
      result = null;
    }
    return result;
  }



If so,  hook (listener, writer calls ) for GET callbacks are ok as shown in
red colour...?

*LocalRegion.java*

public final Object getDeserializedValue(RegionEntry re, final KeyInfo
keyInfo, final boolean updateStats, boolean disableCopyOnRead,
          boolean preferCD, EntryEventImpl clientEvent, boolean
returnTombstones, boolean allowReadFromHDFS, boolean retainResult) {
 *    //hook for before GET - call CacheWriter  *
    try{
            if (this.diskRegion != null) {
              this.diskRegion.setClearCountReference();


    //code in try ends here    *//hook for after GET - call CacheListener.*
    }finally {
      if (this.diskRegion != null) {
        this.diskRegion.removeClearCountReference();
      }
    }

    }


Looking forward to a quick help.
