Detailed Description

template<typename T, bool initialize_memory>
class internal::AlignedVectorDefaultInitialize< T, initialize_memory >

Like AlignedVectorInitialize, but use default-constructed objects as initializers.

Template Parameters
initialize_memorySets whether the set command should initialize memory (with a call to the copy constructor) or rather use the copy assignment operator. A template is necessary to select the appropriate operation since some classes might define only one of those two operations.

Constructor & Destructor Documentation

◆ AlignedVectorDefaultInitialize()

template<typename T , bool initialize_memory>
internal::AlignedVectorDefaultInitialize< T, initialize_memory >::AlignedVectorDefaultInitialize ( const std::size_t  size,
T *const  destination 
)
inline

Constructor. Issues a parallel call if there are sufficiently many elements, otherwise work in serial.

Definition at line 982 of file aligned_vector.h.

Member Function Documentation

◆ apply_to_subrange()

template<typename T , bool initialize_memory>
virtual void internal::AlignedVectorDefaultInitialize< T, initialize_memory >::apply_to_subrange ( const std::size_t  begin,
const std::size_t  end 
) const
inlineoverridevirtual

This initializes elements on a subrange given by two integers.

Implements parallel::ParallelForInteger.

◆ default_construct_or_assign() [1/2]

template<typename T , bool initialize_memory>
void internal::AlignedVectorDefaultInitialize< T, initialize_memory >::default_construct_or_assign ( const std::size_t  begin,
const std::size_t  end,
std::integral_constant< bool, false >   
) const

◆ default_construct_or_assign() [2/2]

template<typename T , bool initialize_memory>
void internal::AlignedVectorDefaultInitialize< T, initialize_memory >::default_construct_or_assign ( const std::size_t  begin,
const std::size_t  end,
std::integral_constant< bool, true >   
) const
inlineprivate

Definition at line 1030 of file aligned_vector.h.

◆ apply_parallel()

void parallel::ParallelForInteger::apply_parallel ( const std::size_t  begin,
const std::size_t  end,
const std::size_t  minimum_parallel_grain_size 
) const
inlineinherited

This function runs the for loop over the given range [lower,upper), possibly in parallel when end-begin is larger than the minimum parallel grain size. This function is marked const because it any operation that changes the data of a derived class will inherently not be thread-safe when several threads work with the same data simultaneously.
