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

Constructor & Destructor Documentation

DynamicBitset() [1/2]

cvflann::DynamicBitset::DynamicBitset

(

)

default constructor

DynamicBitset() [2/2]

cvflann::DynamicBitset::DynamicBitset

(

size_t

sz

)

only constructor we use in our code

Parameters

sz	the size of the bitset (in bits)

Member Function Documentation

clear()

void cvflann::DynamicBitset::clear

(

)

Sets all the bits to 0

empty()

bool cvflann::DynamicBitset::empty

(

)

const

checks if the bitset is empty

Returns

true if the bitset is empty

reset() [1/2]

void cvflann::DynamicBitset::reset

(

)

set all the bits to 0

reset() [2/2]

void cvflann::DynamicBitset::reset

(

size_t

index

)

set one bit to 0

Parameters

index

reset_block()

void cvflann::DynamicBitset::reset_block

(

size_t

index

)

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

)

resize the bitset so that it contains at least sz bits

Parameters

sz

set()

void cvflann::DynamicBitset::set

(

size_t

index

)

set a bit to true

Parameters

index

the index of the bit to set to 1

size()

size_t cvflann::DynamicBitset::size

(

)

const

gives the number of contained bits

test()

bool cvflann::DynamicBitset::test

(

size_t

index

)

const

check if a bit is set

Parameters

index

the index of the bit to check

Returns

true if the bit is set
