Interface ICountFingerprint

All Superinterfaces:

Serializable

All Known Implementing Classes:

IntArrayCountFingerprint

public interface ICountFingerprint
extends Serializable

Interface for count fingerprint representations. The fingerprint is regarded as a list of hashes and a list of counts where the the list of counts keeps track of how many times the corresponding hash is found in the fingerprint. So index refers to position in the list. The list must be sorted in natural order (ascending).

Method Summary

Methods

Modifier and Type	Method and Description
int	getCount(int index) Returns the count value for the bin with the given index.
int	getCountForHash(int hash) Get the number of times a certain hash exists in the fingerprint.
int	getHash(int index) Returns the hash corresponding to the given index in the fingerprint.
boolean	hasHash(int hash) Whether the fingerprint contains the given hash.
void	merge(ICountFingerprint fp) Merge all from fp into the current fingerprint.
int	numOfPopulatedbins() Returns the number of bins that are populated.
void	setBehaveAsBitFingerprint(boolean behaveAsBitFingerprint) Changes behaviour, if true is given the count fingerprint will behave as a bit fingerprint and return 0 or 1 for counts.
long	size() Returns the number of bits of this fingerprint.

Method Detail

size

long size()

Returns the number of bits of this fingerprint.

Returns:

the size of the fingerprint.

numOfPopulatedbins

int numOfPopulatedbins()

Returns the number of bins that are populated. This number is typically smaller then the total number of bins.

Returns:

the number of populated bins

size()

getCount

int getCount(int index)

Returns the count value for the bin with the given index.

Parameters:

index - the index of the bin to return the number of hits for.

Returns:

the count for the bin with given index.

getHash

int getHash(int index)

Returns the hash corresponding to the given index in the fingerprint.

Parameters:

index - the index of the bin to return the hash for.

Returns:

the hash for the bin with the given index.

merge

void merge(ICountFingerprint fp)

Merge all from fp into the current fingerprint.

Parameters:

fp - to be merged

setBehaveAsBitFingerprint

void setBehaveAsBitFingerprint(boolean behaveAsBitFingerprint)

Changes behaviour, if true is given the count fingerprint will behave as a bit fingerprint and return 0 or 1 for counts.

Parameters:

behaveAsBitFingerprint -

hasHash

boolean hasHash(int hash)

Whether the fingerprint contains the given hash.

Parameters:

hash -

Returns:

true if the fingerprint contains the given hash, otherwise false.

getCountForHash

int getCountForHash(int hash)

Get the number of times a certain hash exists in the fingerprint.

Parameters:

hash -

Returns:

the number associated with the given hash
