Constructor & Destructor Documentation

IdentifierHashCalc() [1/2]

template<class T>

IdentifierHashCalc< T >::IdentifierHashCalc

(

)

Default constructor makes empty hash table.

Member Function Documentation

addEntry()

template<class T>

bool IdentifierHashCalc< T >::addEntry

(

const IdType &

id

)

Add an identifier to the table.

checkValidity()

template<class T>

bool IdentifierHashCalc< T >::checkValidity

(

)

const

Check that the table is internally consistent.

An empty table will return false.

clear()

template<class T>

void IdentifierHashCalc< T >::clear

(

)

Clear the hashtable.

dump()

template<class T>

void IdentifierHashCalc< T >::dump

(

std::ostream &

os = std::cout

)

const

Dump complete table to output stream.

dumpToString()

template<class T>

std::string IdentifierHashCalc< T >::dumpToString

(

)

const

Dump complete table into a string.

getHash()

template<class T>

HashType IdentifierHashCalc< T >::getHash

(

const IdType &

id

)

const

Get hash from 0 to size()-1.

Returns invalid hash if id is not in table.

getIdentifier()

template<class T>

IdType IdentifierHashCalc< T >::getIdentifier

(

const HashType &

idHash

)

const

Get identifier from hash.

Returns invalid identifier if hash is out of range.

isInRange()

template<class T>

bool IdentifierHashCalc< T >::isInRange ( const T & idFields ) const

private

setFieldLimits()

template<class T>

void IdentifierHashCalc< T >::setFieldLimits	(	unsigned int	fieldIndex,
		int	fieldMin,
		int	fieldMax )

size()

template<class T>

unsigned int IdentifierHashCalc< T >::size

(

)

const

Number of hashes in the table.

update()

template<class T>

void IdentifierHashCalc< T >::update ( )

private
