Method Details

DistributedBinomialLadderFilterController() public méthode

Construct the controller (server) for requests to this host for its shards of the binomial ladder filter.

public DistributedBinomialLadderFilterController ( DistributedBinomialLadderFilterClient distributedBinomialLadderFilterClient, int numberOfBitsPerShard, string secretSaltToPreventAlgorithmicComplexityAttacks ) : System.Collections.Generic
distributedBinomialLadderFilterClient	StopGuessing.Clients.DistributedBinomialLadderFilterClient	A client used by this server to access the servers hosting other shards of the filter.
numberOfBitsPerShard	int	The number of bits that each shard should contain.
secretSaltToPreventAlgorithmicComplexityAttacks	string	/// A secret used to salt the filter's hash functions so as to prevent attacks that might try to find collisions in the small space we are hashing to.
Résultat	System.Collections.Generic

GetShard() protected méthode

Get the fitler array that stores a shard based on the shard number.

protected GetShard ( int shardNumber ) : FilterArray
shardNumber	int	The shard number (index) to get.
Résultat	StopGuessing.DataStructures.FilterArray

GetShard() protected méthode

Get the fitler array that stores a shard associated with a given element.

protected GetShard ( string element ) : FilterArray
element	string	The element to associate with a shard.
Résultat	StopGuessing.DataStructures.FilterArray

Property Details

FilterClient protected_oe property

Since the filter is distributed into shards which are stored on many hosts, we need a client to access the shards of the filter that are stored on other hosts.

Résultat	StopGuessing.Clients.DistributedBinomialLadderFilterClient

NumberOfBitsPerShard protected_oe property

The number of bits stored in each shard.

protected int NumberOfBitsPerShard
Résultat	int

SecretSaltToPreventAlgorithmicComplexityAttacks protected_oe property

A secret string used to salt hashes so as to prevent algorithmic complexity attacks.

protected string SecretSaltToPreventAlgorithmicComplexityAttacks
Résultat	string

ShardsByIndex protected_oe property

The shards of the filter that this host has a (not-necessarily-up-to-date) copy of.
