Detailed Description

template<typename T>
class open3d::core::SmallVectorTemplateBase< T, true >

SmallVectorTemplateBase<TriviallyCopyable = true> - This is where we put method implementations that are designed to work with trivially copyable T's. This allows using memcpy in place of copy/move construction and skipping destruction.

Member Typedef Documentation

◆ ValueParamT

template<typename T>
using open3d::core::SmallVectorTemplateBase< T, true >::ValueParamT
protected
Initial value:
typename std::conditional<TakesParamByValue, T, const T &>::type

Either const T& or T, depending on whether it's cheap enough to take parameters by value.

Constructor & Destructor Documentation

◆ SmallVectorTemplateBase()

template<typename T>
open3d::core::SmallVectorTemplateBase< T, true >::SmallVectorTemplateBase ( size_t Size)

Member Function Documentation

◆ destroy_range()

template<typename T>
void open3d::core::SmallVectorTemplateBase< T, true >::destroy_range ( T * ,
T *  )
inlinestaticprotected

◆ forward_value_param()

template<typename T>
ValueParamT open3d::core::SmallVectorTemplateBase< T, true >::forward_value_param ( ValueParamT V)
inlinestaticprotected

Copy V or return a reference, depending on ValueParamT.

◆ grow()

template<typename T>
void open3d::core::SmallVectorTemplateBase< T, true >::grow ( size_t MinSize = 0)
inlineprotected

Double the size of the allocated memory, guaranteeing space for at least one more element or MinSize if specified.

◆ growAndAssign()

template<typename T>
void open3d::core::SmallVectorTemplateBase< T, true >::growAndAssign ( size_t NumElts,
T Elt )

inlineprotected

◆ mallocForGrow()

T * open3d::core::SmallVectorTemplateBase< T, bool >::mallocForGrow ( size_t MinSize,
size_t & NewCapacity )
inlineprotected

Create a new allocation big enough for MinSize and pass back its size in NewCapacity. This is the first section of grow().

◆ moveElementsForGrow()

void open3d::core::SmallVectorTemplateBase< T, TriviallyCopyable >::moveElementsForGrow ( T * NewElts)
protected

Move existing elements over to the new allocation NewElts, the middle section of grow().

template<typename T>
const T * open3d::core::SmallVectorTemplateBase< T, true >::reserveForParamAndGetAddress ( const T & Elt,

template<typename T>
T * open3d::core::SmallVectorTemplateBase< T, true >::reserveForParamAndGetAddress ( T & Elt,
size_t N = 1 )

◆ takeAllocationForGrow()

void open3d::core::SmallVectorTemplateBase< T, TriviallyCopyable >::takeAllocationForGrow ( T * NewElts,
size_t NewCapacity )
protected

Transfer ownership of the allocation, finishing up grow().

Field Documentation

◆ TakesParamByValue

template<typename T>
bool open3d::core::SmallVectorTemplateBase< T, true >::TakesParamByValue = sizeof(T) <= 2 * sizeof(void *)
staticconstexprprotected

True if it's cheap enough to take parameters by value. Doing so avoids overhead related to mitigations for reference invalidation.
