Detailed Description

template<size_t _N>
class Ogre::cbitset32< _N >

This is similar to std::bitset, except waaay less bloat.

cbitset32 stands for constant/compile-time bitset with an internal representation of 32-bits

2^5 = 32 0x1F = 32 - 1 = 5 bits set

Remarks

IMPORTANT: To use this class, you MUST include OgreBitset.inl in your cpp file This split into *.h and *.inl was to avoid bloating build times of headers that include OgreBitset.h

Parameters

_N	Number of bits this bitset will hold

Member Function Documentation

capacity()

size_t Ogre::cbitsetN< _N, uint32 , _bits, _mask >::capacity ( ) const

inlineinherited

Return maximum number of bits this bitset can hold.

clear()

void Ogre::cbitsetN< _N, uint32 , _bits, _mask >::clear ( )

inlineinherited

Sets all bits to 0.

empty()

bool Ogre::cbitsetN< _N, uint32 , _bits, _mask >::empty ( ) const

inherited

Returns true if all bits are unset.

numBitsSet()

size_t Ogre::cbitsetN< _N, uint32 , _bits, _mask >::numBitsSet ( const size_t  positionEnd ) const

inherited

Returns the number of bits that are set between range [0; positionEnd).

set()

void Ogre::cbitsetN< _N, uint32 , _bits, _mask >::set ( const size_t  position )

inherited

Sets bit at 'position' to 1.

Parameters

position

Value in range [0; _N)

setAll()

void Ogre::cbitsetN< _N, uint32 , _bits, _mask >::setAll ( )

inherited

Sets all bits to 1.

setAllUntil()

void Ogre::cbitsetN< _N, uint32 , _bits, _mask >::setAllUntil ( size_t  position )

inherited

Sets all bits in range [0; position) It's the same as calling:

for( size_t i = 0u; i < position; ++i ) this->set( i );

Values in range [position; _N) are left untouched

Parameters

position

setValue()

void Ogre::cbitsetN< _N, uint32 , _bits, _mask >::setValue ( const size_t  position, const bool  bValue  )

inherited

Sets bit at 'position'.

Parameters

position	Value in range [0; _N)
bValue

test()

bool Ogre::cbitsetN< _N, uint32 , _bits, _mask >::test ( const size_t  position ) const

inherited

Returns true if bit at 'position' is 1.

Parameters

position

Value in range [0; _N)

unset()

void Ogre::cbitsetN< _N, uint32 , _bits, _mask >::unset ( const size_t  position )

inherited

Sets bit at 'position' to 0.

Parameters

position

Value in range [0; _N)
