Detailed Description

template<typename T>
class BidirectionalMap< T >

Bidirectional map templated by <T, unsigned int>.

Store pairs of value and its position (index) and allow bidirectional search. Items of both (values, positions) must be unique.

Constructor & Destructor Documentation

BidirectionalMap()

template<typename T >

BidirectionalMap< T >::BidirectionalMap

inline

Constructor.

Definition at line 73 of file bidirectional_map.hh.

Member Function Documentation

add_item()

template<typename T >

unsigned int BidirectionalMap< T >::add_item ( T  val )

inline

Add new item at the end position of map.

Definition at line 95 of file bidirectional_map.hh.

Here is the caller graph for this function:

get_position()

template<typename T >

int BidirectionalMap< T >::get_position ( T  val ) const

inline

Return position of item of given value.

Definition at line 103 of file bidirectional_map.hh.

Here is the caller graph for this function:

operator[]()

template<typename T >

T BidirectionalMap< T >::operator[] ( unsigned int  pos ) const

inline

Return value on given position.

Definition at line 129 of file bidirectional_map.hh.

reinit()

template<typename T >

void BidirectionalMap< T >::reinit ( unsigned int  init_size = 0 )

inline

Reset data of map, allow reserve size.

Definition at line 110 of file bidirectional_map.hh.

Here is the caller graph for this function:

resize()

template<typename T >

void BidirectionalMap< T >::resize ( unsigned int  new_size )

inline

Reset data of map, reserve space for given size.

Resizes to given new_size if new size is smaller than the actual. The rest of data are thrown away and removed from the map.

Definition at line 118 of file bidirectional_map.hh.

Here is the caller graph for this function:

set_item()

template<typename T >

void BidirectionalMap< T >::set_item ( T  val, unsigned int  pos  )

inline

Set value of given position.

Position must be in interval set in reinit method <0, init_size-1>. Element on every position can be set only once.

Definition at line 82 of file bidirectional_map.hh.

Here is the caller graph for this function:

size()

template<typename T >

unsigned int BidirectionalMap< T >::size

inline

Return size of map.

Definition at line 77 of file bidirectional_map.hh.

Here is the caller graph for this function:

Member Data Documentation

vals_map_

template<typename T >

std::map<T, unsigned int> BidirectionalMap< T >::vals_map_

private

Maps values to indexes into vals_vec_.

Definition at line 68 of file bidirectional_map.hh.

vals_vec_

template<typename T >

std::vector<T> BidirectionalMap< T >::vals_vec_

private

Space to save values.
