Detailed Description

template<typename T>
struct internal::VectorizedArrayTrait< T >

Definition at line 6404 of file vectorization.h.

Member Typedef Documentation

◆ value_type

template<typename T >
using internal::VectorizedArrayTrait< T >::value_type = T

Define scalar value type.

Definition at line 6409 of file vectorization.h.

◆ vectorized_value_type

template<typename T >
using internal::VectorizedArrayTrait< T >::vectorized_value_type = VectorizedArray<T>

Define vectorized value type for internal vectorization.

Definition at line 6423 of file vectorization.h.

Member Function Documentation

◆ width()

template<typename T >
static constexpr std::size_t internal::VectorizedArrayTrait< T >::width ( )
inlinestaticconstexpr

Return the width of template type.

Definition at line 6415 of file vectorization.h.

◆ stride()

template<typename T >
static constexpr std::size_t internal::VectorizedArrayTrait< T >::stride ( )
inlinestaticconstexpr

Return a stride which defines how often the template type T fits into the vectorized_value_type. This is useful to write vectorized templated code where the internal computation is vectorized and the user interface is optionally scalar or also vectorized.

Definition at line 6432 of file vectorization.h.

◆ get() [1/2]

template<typename T >
static value_type & internal::VectorizedArrayTrait< T >::get ( value_type value,
unsigned int  c 
)
inlinestatic

Get a reference to scalar value (on lane 0).

Definition at line 6441 of file vectorization.h.

◆ get() [2/2]

template<typename T >
static const value_type & internal::VectorizedArrayTrait< T >::get ( const value_type value,
unsigned int  c 
)
inlinestatic

Get a read-only reference to scalar value (on lane 0).

Definition at line 6453 of file vectorization.h.

◆ get_from_vectorized() [1/2]

template<typename T >
static value_type & internal::VectorizedArrayTrait< T >::get_from_vectorized ( vectorized_value_type values,
unsigned int  c 
)
inlinestatic

Get a reference to scalar value on lane c from a vectorized values field.

Definition at line 6465 of file vectorization.h.

◆ get_from_vectorized() [2/2]

template<typename T >
static const value_type & internal::VectorizedArrayTrait< T >::get_from_vectorized ( const vectorized_value_type values,
unsigned int  c 
)
inlinestatic

Get a read-only reference to scalar value on lane c from a vectorized values field.

Definition at line 6477 of file vectorization.h.
