Detailed Description

template<class Size_T>
class open3d::core::SmallVectorBase< Size_T >

This is all the stuff common to all SmallVectors.

The template parameter specifies the type which should be used to hold the Size and Capacity of the SmallVector, so it can be adjusted. Using 32 bit size is desirable to shrink the size of the SmallVector. Using 64 bit size is desirable for cases like SmallVector<char>, where a 32 bit size would limit the vector to ~4GB. SmallVectors are used for buffering bitcode output - which can exceed 4GB.

grow_pod()

template<class Size_T>

void open3d::core::SmallVectorBase< Size_T >::grow_pod ( void * FirstEl, size_t MinSize, size_t TSize )

protected

This is an implementation of the grow() method which only works on POD-like data types and is out of line to reduce code duplication. This function will report a fatal error if it cannot increase capacity.

mallocForGrow()

template<class Size_T>

void * open3d::core::SmallVectorBase< Size_T >::mallocForGrow ( size_t MinSize, size_t TSize, size_t & NewCapacity )

protected

This is a helper for grow() that's out of line to reduce code duplication. This function will report a fatal error if it can't grow at least to MinSize.

set_size()

template<class Size_T>

void open3d::core::SmallVectorBase< Size_T >::set_size ( size_t N )

inlineprotected

Set the array size to N, which the current array must have enough capacity for.

This does not construct or destroy any elements in the vector.

size()

template<class Size_T>

size_t open3d::core::SmallVectorBase< Size_T >::size ( ) const

inline

SizeTypeMax()

template<class Size_T>

constexpr size_t open3d::core::SmallVectorBase< Size_T >::SizeTypeMax ( )

inlinestaticconstexprprotected

The maximum value of the Size_T used.
