Description

A container in DASH is a set of elements of a the same type that is distributed to units in a team according to a specified distribution pattern. Container elements can be iterated canonically in global and local memory.

Types

Type name	Description
`value_type`	Type of the container elements.
`difference_type`	Integer type denoting a distance in cartesian index space.
`index_type`	Integer type denoting an offset/coordinate in cartesian index space.
`size_type`	Integer type denoting an extent in cartesian index space.
`iterator`	Iterator on container elements in global index space.
`const_iterator`	Iterator on const container elements in global index space.
`reverse_iterator`	Reverse iterator on container elements in global index space.
`const_reverse_iterator`	Reverse iterator on const container elements in global index space.
`reference`	Reference on container elements in global index space.
`const_reference`	Reference on const container elements in global index space.
`local_pointer`	Native pointer on local container elements.
`const_local_pointer`	Native pointer on const local container elements.
`view_type`	View specifier on container elements, model of `DashViewConcept`.
`local_type`	Reference to local element range, allows range-based iteration.
`pattern_type`	Concrete model of the Pattern concept that specifies the container's data distribution and cartesian access pattern.

Member Functions

Return Type	Method	Parameters	Description
`local_type`	`local`		Container proxy object representing a view specifier on the container's local elements.
`pattern_type`	`pattern`		Object implementing the Pattern concept specifying the container's data distribution and iteration pattern.
`iterator`	`begin`		Iterator referencing the first container element.
`iterator`	`end`		Iterator referencing the element past the last container element.
`Element *`	`lbegin`		Native pointer referencing the first local container element, same as `local().begin()`.
`Element *`	`lend`		Native pointer referencing the element past the last local container element, same as `local().end()`.
`size_type`	`size`		Number of elements in the container.
`size_type`	`local_size`		Number of local elements in the container, same as `local().size()`.
`bool`	`is_local`	`index_type gi`	Whether the element at the given linear offset in global index space `gi` is local.
`bool`	`allocate`	`size_type n, DistributionSpec<DD> ds, Team t`	Allocation of `n` container elements distributed in Team `t` as specified by distribution spec `ds`
`void`	`deallocate`		Deallocation of the container and its elements.

Non-member Functions

Return Type	Method	Parameters	Description
`C::size_type`	`dash::size`	`const C & container`	Returns the size of a container
`bool`	`dash::empty`	`const C & container`	Checks whether a container is empty
