Methods Summary
public java.lang.LonggetCurrentSize()
Returns the current size of the cache in bytes

public java.lang.LonggetMaxSize()
Returns the upper bound on the cache size

        Object object = boundedMultiLruCache.getStatByName(
                                        Constants.STAT_BOUNDEDMULTILRUCACHE_MAX_SIZE);
        /*
         * BoundedMultiLruCache class returns java.lang.String with a value 
         * "default" if the maxSize == Constants.DEFAULT_MAX_CACHE_SIZE
         * To take care of this case, the if/else is added below
         */
