Class BWCTestWriter

java.lang.Object

util.AbstractWriter

tx.BWCTestWriter

All Implemented Interfaces:

com.gemstone.gemfire.cache.CacheCallback, com.gemstone.gemfire.cache.CacheWriter, com.gemstone.gemfire.cache.Declarable

public class BWCTestWriter
extends AbstractWriter
implements com.gemstone.gemfire.cache.CacheWriter, com.gemstone.gemfire.cache.Declarable

Serial Tx View Test CacheWriter Counts events and validates callback objects and that the event is invoked in the VM where it was created. With pre-70 clients, we cannot validate the memberId (callbackArgs) vs. event.getDistributedMember().

Since:

6.0

beforeRegionClear

public void beforeRegionClear(com.gemstone.gemfire.cache.RegionEvent event)

Specified by:

beforeRegionClear in interface com.gemstone.gemfire.cache.CacheWriter

close

public void close()

Specified by:

close in interface com.gemstone.gemfire.cache.CacheCallback

checkVM

protected void checkVM(com.gemstone.gemfire.cache.EntryEvent event)

Check that this method is running in the same VM where the writer was created. Log an error if any problems are detected. If writers are installed on all regions, the product should prefer a local writer (so it should be in the same VM). Updated with GemFire 6.5: For PartitionedRegions, the CacheWriter will be invoked in the primary dataStore (for the entry).

checkVM

protected void checkVM()

checkCallback

protected void checkCallback(com.gemstone.gemfire.cache.CacheEvent event,
                             String expectedCallbackPrefix)

Check that the callback object is expected. Log an error if any problems are detected.

Parameters:

event - The event object.

expectedCallbackPrefix - - The expected prefix on the callback object (String).

throwException

protected void throwException(String errStr)

Utility method to write an Exception string to the Event Blackboard and to also throw an exception containing the same string.

Parameters:

errStr - String to log, post to TxBB and throw

Throws:

TestException - containing the passed in String

init

public void init(Properties prop)

Specified by:
