public class TxUtilKeyRange
extends TxUtil

A subclass of TxUtil that forces each VM to use a unique range of keys for its random operations, thus no conflicts.

Method Detail

initialize

public void initialize()

Initialize the key ranges

Overrides:

initialize in class TxUtil

getRandomKey

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

Get a random key from the given region that is within this instance's range. If no keys qualify in the region, return null.

Overrides:

getRandomKey in class TxUtil

Parameters:

aRegion - - The region to get the key from.

excludeKey - - The region to get the key from.

createEntry

public Operation createEntry(com.gemstone.gemfire.cache.Region aRegion,
                             boolean exists)

Creates a new key/value in the given region by creating a new key within the range and a random value.

Overrides:

createEntry in class TxUtil

Parameters:

aRegion - The region to create the new key in.

exists - Not used in this overridden method; this test wants to use unique keys even on creates, so we don't do anything different here based on the value of exists.

Returns:

An instance of Operation describing the create operation.

printKeyRange

public void printKeyRange(com.gemstone.gemfire.cache.Region aRegion)
