question: private static int maxBucketsPerElement ( long numElements ) { numElements = Math . max ( 1 , numElements ) ; double v = ( Integer . MAX_VALUE - EXCESS ) / ( double ) numElements ; if ( v < 1.0 ) { throw new UnsupportedOperationException ( "Cannot compute probabilities for " + numElements + " elements." ) ; } return Math . min ( BloomCalculations . probs . length - 1 , ( int ) v ) ; }
target:  Calculates the maximum number of buckets per element that this implementation can support. Crucially, it will lower the bucket count if necessary to meet BitSet's size restrictions.
