Method set_array

deps/darts-clone-0.32h/include/darts.h:173–177

set_array() calls clear() in order to free memory allocated to the old array and then sets a new array. This function is useful to set a memory- mapped array. Note that the array set by set_array() is not freed in clear() and the destructor of . set_array() can also set the size of the new array but the size is not used in search methods. So it works well even if the 2nd argument

  // used in search methods. So it works well even if the 2nd argument is 0 or
  // omitted. Remember that size() and total_size() returns 0 in such a case.
  void set_array(const void *ptr, std::size_t size = 0) {
    clear();
    array_ = static_cast<const unit_type *>(ptr);
    size_ = size;
  }
  void copy_array(const void* ptr, std::size_t num_bytes) {
    clear();
    const std::size_t extra_padding = num_bytes % unit_size() == 0 ? 0 : 1;
