Detailed Description

See cbitset64.

This is the same, but the maximum number of bits is not known at build time

Constructor & Destructor Documentation

bitset64()

Ogre::bitset64::bitset64 ( )

inline

Member Function Documentation

capacity()

size_t Ogre::bitset64::capacity ( ) const

inline

Return maximum number of bits this bitset can hold.

clear()

void Ogre::bitset64::clear ( )

inline

Sets all bits to 0.

References Ogre::FastArray< T >::begin(), and Ogre::FastArray< T >::size().

empty()

bool Ogre::bitset64::empty ( ) const

inline

Returns true if all bits are unset.

findFirstBitSet()

size_t Ogre::bitset64::findFirstBitSet ( ) const

inline

Finds the first bit set.

Returns

The index to the first unset bit returns this->capacity() if all bits are unset (i.e. all 0s)

findLastBitSetPlusOne()

size_t Ogre::bitset64::findLastBitSetPlusOne ( ) const

inline

Finds the first bit unset after the last bit set.

Returns

If all bits are unset (i.e. all 0s): Returns 0 If at least one bit is set: The index to the last set bit, plus one. Return range is [1; capacity]

numBitsSet()

size_t Ogre::bitset64::numBitsSet ( const size_t  positionEnd ) const

inline

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

reset()

void Ogre::bitset64::reset ( size_t  bitsCapacity )

inline

References Ogre::FastArray< T >::clear(), and Ogre::FastArray< T >::resizePOD().

set()

void Ogre::bitset64::set ( const size_t  position )

inline

Sets bit at 'position' to 1.

Parameters

position

Value in range [0; _N)

setAll()

void Ogre::bitset64::setAll ( )

inline

Sets all bits to 1.

setAllUntil()

void Ogre::bitset64::setAllUntil ( size_t  position )

inline

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::bitset64::setValue ( const size_t  position, const bool  bValue  )

inline

Sets bit at 'position'.

Parameters

position	Value in range [0; _N)
bValue

test()

bool Ogre::bitset64::test ( const size_t  position ) const

inline

Returns true if bit at 'position' is 1.

Parameters

position

Value in range [0; _N)

unset()

void Ogre::bitset64::unset ( const size_t  position )

inline

Sets bit at 'position' to 0.

Parameters

position

Value in range [0; _N)
