Detailed Description

template<typename C>
class stapl::repeat_view< C >

A view that can provide infinite copies of the same element.

Template Parameters

T	The type of element to be repeated.

Constructor & Destructor Documentation

repeat_view() [1/3]

template<typename C>

stapl::repeat_view< C >::repeat_view	(	view_container_type *	vcont,
		domain_type	dom = domain_type(),
		map_func_type	mfunc = map_func_type()
	)

Constructor used to pass ownership of the container to the view.

Parameters

vcont	pointer to the container used to forward the operations.
dom	domain to be used by the view.
mfunc	mapping function to transform view indices to container gids.

repeat_view() [2/3]

template<typename C>

stapl::repeat_view< C >::repeat_view	(	view_container_type const &	vcont,
		domain_type	dom,
		map_func_type	mfunc = map_func_type()
	)

Constructor that does not takes ownership over the passed container.

Parameters

vcont	reference to the container used to forward the operations.
dom	domain to be used by the view.
mfunc	mapping function to transform view indices to container gids.

repeat_view() [3/3]

template<typename C>

stapl::repeat_view< C >::repeat_view	(	view_container_type const &	vcont,
		domain_type	dom,
		map_func_type	mfunc,
		repeat_view< C > const &
	)

Constructor that does not takes ownership over the passed container.

Parameters

vcont	reference to the container used to forward the operations.
dom	domain to be used by the view.
mfunc	mapping function to transform view indices to container gids.

Member Function Documentation

get_container()

view_container_type* stapl::core_view< C, view_traits< repeat_view< C > >::domain_type , view_traits< repeat_view< C > >::map_function >::get_container ( void  ) const

inherited

container()

view_container_type& stapl::core_view< C, view_traits< repeat_view< C > >::domain_type , view_traits< repeat_view< C > >::map_function >::container ( void  ) const

inherited

get_element()

value_type stapl::view_operations::read< repeat_view< C > >::get_element ( index_t const &  index ) const

inherited

Get the element index from the container.

Parameters

index

of element to get

get_element_split()

future<value_type> stapl::view_operations::read< repeat_view< C > >::get_element_split ( index_t const &  index ) const

inherited

Get the element index from the container.

Parameters

index

of element to get

apply_get() [1/2]

Functor::result_type stapl::view_operations::read< repeat_view< C > >::apply_get ( index_t const &  index, Functor  f  )

inherited

Applies the provided function to the value referenced for the given index and returns the result of the operation.

Parameters

index	of element to apply the function
f	function to apply

Returns

result of evaluate the function f on the value referenced for the index

apply_get() [2/2]

Functor::result_type stapl::view_operations::read< repeat_view< C > >::apply_get ( index_t const &  index, Functor  f  ) const

inherited

next()

index_t stapl::view_operations::sequence< repeat_view< C > , detail::view_iterator< repeat_view< C > > >::next ( index_t const &  index ) const

inherited

Computes the next index based on the given index.

Overwriting this method allows produce a different way to traverse the elements referenced by the view.

prev()

index_t stapl::view_operations::sequence< repeat_view< C > , detail::view_iterator< repeat_view< C > > >::prev ( index_t const &  index ) const

inherited

Computes the previous index based on the given index.

Overwriting this method allows produce a different way to traverse the elements referenced by the view.

advance()

index_t stapl::view_operations::sequence< repeat_view< C > , detail::view_iterator< repeat_view< C > > >::advance ( index_t const &  index, Distance  n  ) const

inherited

Computes the new index after advance n positions from the given index.

Overwriting this method allows produce a different way to traverse the elements referenced by the view.
