Detailed Description

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

cbitset64 stands for constant/compile-time bitset with an internal representation of 64-bits

2^6 = 64 0x3F = 64 - 1 = 6 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

template<size_t _N>

size_t Ogre::cbitset64< _N >::findFirstBitSet ( ) const

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)

template<size_t _N>

size_t Ogre::cbitset64< _N >::findLastBitSetPlusOne ( ) const

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]
