Class Feeder

java.lang.Object

delta.Feeder

public class Feeder
extends java.lang.Object

REGION_NAME

protected static final java.lang.String REGION_NAME

deltaType

protected final java.lang.String deltaType

LAST_KEY

public static final java.lang.String LAST_KEY

The last key to be put by feeder. This is used to signal for proceeding with the validation in some tests

Method Detail

createEntry

protected static void createEntry(com.gemstone.gemfire.cache.Region region)

Perform create operation for a random key within PUT_KEY_RANGE

Parameters:

region - - the test region

updateEntry

protected static void updateEntry(com.gemstone.gemfire.cache.Region region)

Perform put operation for a random key within PUT_KEY_RANGE

Parameters:

region - - the test region

invalidateEntry

protected static void invalidateEntry(com.gemstone.gemfire.cache.Region region)

Perform invalidate operation for a random key within PUT_KEY_RANGE

Parameters:

region - - the test region

destroyEntry

protected static void destroyEntry(com.gemstone.gemfire.cache.Region region)

Perform destroy operation for a random key within PUT_KEY_RANGE

Parameters:

region - - the test region

registerInterest

protected static void registerInterest(com.gemstone.gemfire.cache.Region region)

Perform registerInterest operation for a random key within PUT_KEY_RANGE

Parameters:

region - - the test region

unregisterInterest

protected static void unregisterInterest(com.gemstone.gemfire.cache.Region region)

Perform unregisterInterest operation for a random key within PUT_KEY_RANGE

Parameters:

region - - the test region

feederTimedTask

public static void feederTimedTask()

Does feederTask() for DeltaPropagationPrms.feederTaskTimeSec.

feederTask

public static void feederTask()

Increments the value of counters in threadList for each thread and notifies all the put threads int wait().

populateSharedMapWithRegionData

public static void populateSharedMapWithRegionData()

closeTask

public static void closeTask()

Signals for stopping of the put threads and notifies all. Waits till all the put threads are complete and decrements the shared counter for TOTAL_UPDATES by TOTAL_PUT_THREADS * PUT_KEY_RANGE. This is done because the first set of PUTs by each thread will correspond to CREATE operations and UPDATES afterwards.

verifyDeltaFailuresInC2S

public static void verifyDeltaFailuresInC2S()

verifyDeltaFailuresInP2P

public static void verifyDeltaFailuresInP2P()

verifyDeltaFailuresInS2C

public static void verifyDeltaFailuresInS2C()

waitForFeederThreadsToComplete

public static void waitForFeederThreadsToComplete()

Signals for stopping of the put threads and notifies all. Waits till all the put threads are complete. Signals to other VMs that the feed cyle is over.

getLatestValue

protected static java.lang.Long getLatestValue(java.lang.String key,
                                               java.lang.String threadIdKey)

Gets the latest value for the given key from the latestValues map and returns the incremented value for doing entry operations.

Parameters:

key - - the event key

threadIdKey - - thread-id to which this key belongs

Returns:

- the latest incremented value for this key

getLatestDelta

protected static DeltaTestObj getLatestDelta(java.lang.String key,
                                             java.lang.String threadIdKey,
                                             boolean isCreate)

Gets the latest delta for the given key from the latestValues map and returns the incremented value for doing entry operations.

Parameters:

key - - the event key

threadIdKey - - thread-id to which this key belongs

isCreate - - create or update operation

Returns:

- the latest incremented delta for this key

updateLatestValueMap

protected static boolean updateLatestValueMap(com.gemstone.gemfire.cache.Region region,
                                              java.lang.String key,

Returns:

- whether to proceed with the calling invalidate or destroy operation or not.

Throws:
