Constructor & Destructor Documentation

◆ IdentifierHashCalc() [1/2]

template<class T >
IdentifierHashCalc< T >::IdentifierHashCalc ( )

Default constructor makes empty hash table.

◆ IdentifierHashCalc() [2/2]

template<class T >
IdentifierHashCalc< T >::IdentifierHashCalc ( const T &  idFields)
explicit

Make empty table with pointer set to external idHelper, which will be transmitted to the constructor of class T.

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 
)

Set the limits of a specific field.

◆ 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
