ContainerRange

[req.container_range]

ContainerRange is a range that represents a concurrent container or a part of the container.

The ContainerRange object can be used to traverse the container in parallel algorithms like parallel_for.

The type CR satisfies the ContainerRange requirements if:

• The type CR meets the requirements of Range requirements.

• The type CR provides the following member types and functions:

  type CR::value_type
  

  The type of the item in the range.

  type CR::reference
  

  Reference type to the item in the range.

  type CR::const_reference
  

  Constant reference type to the item in the range.

  type CR::iterator
  

  Iterator type for range traversal.

  type CR::size_type
  

  Unsigned integer type for obtaining grain size.

  type CR::difference_type
  

  The type of the difference between two iterators.

  iterator CR::begin()
  

  Returns an iterator to the beginning of the range.

  iterator CR::end()
  

  Returns an iterator to the position that follows the last element in the range.

  size_type CR::grainsize() const
  

  Returns the range grain size.
