/**
* A cache adapter for setting flags for each individual cache operation called
* within the scope of a TreeCache operation.
*
* Note: We can't just wrap around use of cache in tree module because flag
* assignment needs to extend even to calls within AtomicHashMapProxy.getDeltaMapForWrite().
* So, the only possible way is to wrap around the Cache instance around
* something that sets flags accordingly.
