Detailed Description

template<typename View>
struct stapl::view_impl::native_partition< View >

Represent a collection of domains that matches how the data in distributed on the underlying container associated with the given view.

Template Parameters

View	given to create the partition.

Member Function Documentation

operator[]()

template<typename View >

value_type stapl::view_impl::native_partition< View >::operator[]

(

size_t

index

)

const

Return the subdomain indexed by index.

All the indexes contained in the returned domain reference elements that are in the same location.

Parameters

index

of the domain to return

Returns

the domain associated with index

contained_in()

template<typename View >

template<typename ODom , typename MFG >

std::vector<std::pair<domain_type,bool> > stapl::view_impl::native_partition< View >::contained_in	(	ODom const &	dom,
		MFG const &	mfg
	)

Determine which partition has the elements referenced for the given domain.

The returned information is a collection (possibly empty) of pairs. Each pair contains information about which partitions are included in the given domain and how they are included (True: if is fully contained, False: if it is partially included). The returned collection only has elements if there is at least one partition that contains elements on the given domain.

Example:

Partition: [0..3],[4..6],[7..9],[10..13]
Given domain: [2..9]
Returns: {([0..0],False),([1..2],True)}

Parameters

dom	Domain to compare
mfg	Mapping function generator used to get the associated mapping function to each partition. The generated mapping function is used to project generated partitioned domains into the given domain.

Returns

a vector of pairs.
