Detailed Description

template<typename HashType, typename BucketStorage>
struct UE::MovieScene::TDynamicSparseBitSet< HashType, BucketStorage >

NOTE: This class is currently considered internal only, and should only be used by engine code. A dynamically sized sparse bitset comprising multiple TFixedSparseBitSets.

In theory this class supports the full integer range, it is optimized for small numbers of set bits within a large range, ideally when they occupy the same adjacent space.

Member Function Documentation

CountSetBits()

template<typename HashType , typename BucketStorage >

uint32 UE::MovieScene::TDynamicSparseBitSet< HashType, BucketStorage >::CountSetBits ( ) const

inline

Count the total number of set bits in this container

GetMaxNumBits()

template<typename HashType , typename BucketStorage >

uint32 UE::MovieScene::TDynamicSparseBitSet< HashType, BucketStorage >::GetMaxNumBits ( ) const

inline

Get the maximum number of bits that this bitset supports

IsBitSet()

template<typename HashType , typename BucketStorage >

bool UE::MovieScene::TDynamicSparseBitSet< HashType, BucketStorage >::IsBitSet ( uint32  Bit ) const

inline

Check whether the specified bit index is set

IsEmpty()

template<typename HashType , typename BucketStorage >

bool UE::MovieScene::TDynamicSparseBitSet< HashType, BucketStorage >::IsEmpty ( ) const

inline

Check whether this container has any bits set

operator|=()

template<typename HashType , typename BucketStorage >

TDynamicSparseBitSet< HashType, BucketStorage > & UE::MovieScene::TDynamicSparseBitSet< HashType, BucketStorage >::operator|= ( const TDynamicSparseBitSet< HashType, BucketStorage > &  Other )

inline

SetBit()

template<typename HashType , typename BucketStorage >

ESparseBitSetBitResult UE::MovieScene::TDynamicSparseBitSet< HashType, BucketStorage >::SetBit ( uint32  Bit )

inline

Set the bit at the specified index. Any bits between Num and BitIndex will be considered 0.

Returns

true if the bit was previously considered 0 and is now set, false if it was already set.
