Detailed Description

template<typename T>
class internal::AlignedVectorMove< T >

Like AlignedVectorCopy, but use move operations instead of copy operations.

Constructor & Destructor Documentation

AlignedVectorMove()

template<typename T >

internal::AlignedVectorMove< T >::AlignedVectorMove ( T *const  source_begin, T *const  source_end, T *const  destination  )

inline

Constructor. Issues a parallel call if there are sufficiently many elements, otherwise works in serial. Moves the data from the half-open interval between source_begin and source_end to array starting at destination (by calling the move constructor with placement new).

The data is moved between the two arrays by invoking the destructor on the source range (preparing for a subsequent call to free).

Member Function Documentation

apply_to_subrange()

template<typename T >

virtual void internal::AlignedVectorMove< T >::apply_to_subrange ( const std::size_t  begin, const std::size_t  end  ) const

inlineoverridevirtual

This method moves elements from the source to the destination given in the constructor on a subrange given by two integers.

Implements parallel::ParallelForInteger.

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.
