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

cvflann::DynamicBitset::DynamicBitset ( )
inline

default constructor

cvflann::DynamicBitset::DynamicBitset ( size_t  sz)
inline

only constructor we use in our code

Parameters
szthe size of the bitset (in bits)

Member Function Documentation

void cvflann::DynamicBitset::clear ( )
inline

Sets all the bits to 0

bool cvflann::DynamicBitset::empty ( ) const
inline

checks if the bitset is empty

Returns
true if the bitset is empty
void cvflann::DynamicBitset::reset ( )
inline

set all the bits to 0

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

set one bit to 0

Parameters
index
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
void cvflann::DynamicBitset::resize ( size_t  sz)
inline

resize the bitset so that it contains at least sz bits

Parameters
sz
void cvflann::DynamicBitset::set ( size_t  index)
inline

set a bit to true

Parameters
indexthe index of the bit to set to 1
size_t cvflann::DynamicBitset::size ( ) const
inline

gives the number of contained bits

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

check if a bit is set

Parameters
indexthe index of the bit to check
Returns
true if the bit is set
