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

template<typename T >

BidirectionalMap< T >::BidirectionalMap ( )

inline

Constructor.

Definition at line 76 of file bidirectional_map.hh.

Member Function Documentation

template<typename T>

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

inline

Add new item at the end position of map.

Definition at line 106 of file bidirectional_map.hh.

Here is the caller graph for this function:

template<typename T >

void BidirectionalMap< T >::clear ( )

inline

Clear the content. Do not release memory.

Definition at line 121 of file bidirectional_map.hh.

Here is the caller graph for this function:

template<typename T>

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

inline

Return position of item of given value.

Definition at line 114 of file bidirectional_map.hh.

template<typename T >

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

inline

Return value on given position.

Definition at line 145 of file bidirectional_map.hh.

template<typename T >

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

inline

Reset data of map, reserve space for given size.

Definition at line 139 of file bidirectional_map.hh.

Here is the caller graph for this function:

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 128 of file bidirectional_map.hh.

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 86 of file bidirectional_map.hh.

template<typename T >

unsigned int BidirectionalMap< T >::size ( ) const

inline

Return size of map.

Definition at line 80 of file bidirectional_map.hh.

Here is the caller graph for this function:

template<typename T>

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

private

Space to save values.
