indexes::stringology::BitParallelIndex< SymbolType > Class Template Reference

Bit parallel string index. Stores a bit vector for each symbol of the alphabet. The bit vector of symbol a contains true on index i if symbol a is on i-th position in the indexed string. The class does not check whether the bit vectors actually represent valid index. More...

Detailed Description

template<class SymbolType = DefaultSymbolType>
class indexes::stringology::BitParallelIndex< SymbolType >

Bit parallel string index. Stores a bit vector for each symbol of the alphabet. The bit vector of symbol a contains true on index i if symbol a is on i-th position in the indexed string. The class does not check whether the bit vectors actually represent valid index.

Template Parameters

SymbolType

type of symbols of indexed string

Constructor & Destructor Documentation

BitParallelIndex()

template<class SymbolType >

indexes::stringology::BitParallelIndex< SymbolType >::BitParallelIndex ( ext::set< SymbolType >  alphabet, ext::map< SymbolType, ext::vector< bool > >  vectors  )

explicit

Creates a new instance of the index with concrete alphabet and bit vectors.

Parameters

alphabet	the alphabet of indexed string
vectors	the bit vectors
