Detailed Description

template<typename Item>
class gatb::core::tools::collections::impl::Bloom< Item >

Bloom filter implementation.

Constructor & Destructor Documentation

Bloom ( u_int64_t  tai_bloom, size_t  nbHash = 4  )

inline

Constructor.

Parameters

[in]	tai_bloom	: size (in bits) of the bloom filter.
[in]	nbHash	: number of hash functions to use

Member Function Documentation

void dump ( const char *  filename )

inline

Dump the Bloom filter bitset into a file. OBSOLETE

Parameters

[in]

filename

: file where to dump the bitset.

void flush ( )

inlinevirtual

Flush the current content. May be useful for implementation that uses a cache.

Implements Bag< Item >.

std::string getName ( ) const

inlinevirtual

Get the name of the implementation class.

Returns

the class name.

Implements BloomContainer< Item >.

Reimplemented in BloomExtendedNeighborCoherent< Item >, BloomNeighborCoherent< Item >, BloomCacheCoherent< Item >, and BloomSynchronized< Item >.

void insert ( const Item &  item )

inlinevirtual

Implements Bag< Item >.

Reimplemented in BloomExtendedNeighborCoherent< Item >, BloomNeighborCoherent< Item >, BloomCacheCoherent< Item >, and BloomSynchronized< Item >.

unsigned long weight ( )

inlinevirtual

Return the number of 1's in the Bloom (nibble by nibble)

Returns

the weight of the Bloom filter

Implements IBloom< Item >.

Reimplemented in BloomCacheCoherent< Item >.
