Detailed Description

Class re-implementing the boost version of it This helps not depending on boost, it also does not do the bound checks and has a way to reset a block for speed.

DynamicBitset() [1/2]

cvflann::DynamicBitset::DynamicBitset ( )

inline

default constructor

DynamicBitset() [2/2]

Member Function Documentation

clear()

void cvflann::DynamicBitset::clear ( )

inline

Sets all the bits to 0.

empty()

bool cvflann::DynamicBitset::empty ( ) const

inline

checks if the bitset is empty

Returns

true if the bitset is empty

reset() [1/2]

void cvflann::DynamicBitset::reset ( )

inline

set all the bits to 0

Referenced by DynamicBitset().

Here is the caller graph for this function:

reset() [2/2]

void cvflann::DynamicBitset::reset ( size_t  index )

inline

set one bit to 0

Parameters

index

reset_block()

void cvflann::DynamicBitset::reset_block ( size_t  index )

inline

sets a specific bit to 0, and more bits too This function is useful when resetting a given set of bits so that the whole bitset ends up being 0: if that's the case, we don't care about setting other bits to 0

Parameters

index

resize()

void cvflann::DynamicBitset::resize ( size_t  sz )

inline

resize the bitset so that it contains at least sz bits

Parameters

sz

Referenced by DynamicBitset().

Here is the caller graph for this function:

set()

void cvflann::DynamicBitset::set ( size_t  index )

inline

set a bit to true

Parameters

index

the index of the bit to set to 1

Referenced by cvflann::KDTreeIndex< Distance >::getParameters().

Here is the caller graph for this function:

size()

size_t cvflann::DynamicBitset::size ( ) const

inline

gives the number of contained bits

test()

bool cvflann::DynamicBitset::test ( size_t  index ) const

inline

check if a bit is set

Parameters

index

the index of the bit to check

Returns

true if the bit is set
