Class TxViewUtil

java.lang.Object

tx.TxUtil

tx.TxViewUtil

Direct Known Subclasses:

PrViewUtil

public class TxViewUtil
extends TxUtil

A class to contain methods useful for view transactions tests. In this class TxUtil.suspendResume only affects getRandomKey not getValueInVM or containsKey, as these methods are overridden. This is required when verifying the tx state (prior to commit).

Method Detail

HydraTask_createRegionForest

public static void HydraTask_createRegionForest()

Hydra task to create a forest of region hierarchies. This task can be called from more than one thread in the same VM.

containsKey

public boolean containsKey(com.gemstone.gemfire.cache.Region aRegion,
                           Object key)

Call containsKey on the given region and key

Overrides:

containsKey in class TxUtil

Parameters:

aRegion - - The region to test for the key.

key - - The key to use for containsKey.

getValueInVM

public Object getValueInVM(com.gemstone.gemfire.cache.Region aRegion,
                           Object key)

Call getValueInVM on the given region and key. Override TxUtil version which suspends the transaction (View tests only suspend for getRandomKey not for getValueInVM).

Overrides:

getValueInVM in class TxUtil

Parameters:

aRegion - - The region to use for the call.

key - - The key to use for the call.

getValueInVM

public Object getValueInVM(com.gemstone.gemfire.cache.Region aRegion,
                           Object key,
                           boolean translateNullToInvalid)

Overrides:

getValueInVM in class TxUtil

getRandomKey

public Object getRandomKey(com.gemstone.gemfire.cache.Region aRegion,
                           Object excludeKey)

Get a random key from the given region, excluding the key specified by excludeKey. If no keys qualify in the region, return null.

Overrides:

getRandomKey in class TxUtil

Parameters:

aRegion - - The region to get the key from.

excludeKey - - key to exclude
