public class BloomFilter extends Filter
Note: if you are using a custom comparator that ignores some parts
of the keys being compared, you must not use this BloomFilter
and must provide your own FilterPolicy that also ignores the
corresponding parts of the keys. For example, if the comparator
ignores trailing spaces, it would be incorrect to use a
FilterPolicy (like BloomFilter) that does not ignore
trailing spaces in keys.

Callers must delete the result after any database that is using the result has been closed.
public BloomFilter(double bitsPerKey)
bits_per_key: bits per key in bloom filter. A good value for bits_per_key is 9.9, which yields a filter with ~ 1% false positive rate.
Callers must delete the result after any database that is using the result has been closed.
bitsPerKey - number of bits to usepublic BloomFilter(double bitsPerKey,
boolean useBlockBasedMode)
bits_per_key: bits per key in bloom filter. A good value for bits_per_key is 10, which yields a filter with ~ 1% false positive rate.
default bits_per_key: 10
use_block_based_builder: use block based filter rather than full filter. If you want to builder full filter, it needs to be set to false.
default mode: block based filter
Callers must delete the result after any database that is using the result has been closed.
bitsPerKey - number of bits to useuseBlockBasedMode - use block based mode or full filter mode
