Method Summary

Modifier and Type	Method and Description
void	_testMemoryFootprintOfHARegionQueuesWithAndWithoutOverflow() This test verifies that the memory foorprint of the ha region queues is less when ha-overflow is enabled (with an appropriate value of haCapacity) compared to when it is disabled, for the same amount of data feed.
