Detailed Description

template<typename Dom>
struct stapl::rows_partition< Dom >

Partition in rows the given 2D domain.

Template Parameters

Dom	A two dimensional domain type.

Constructor & Destructor Documentation

rows_partition()

template<typename Dom >

stapl::rows_partition< Dom >::rows_partition

(

Dom const &

domain

)

Rows partition constructor.

Example:

Domain to partition: [0..3]x[0..3]
Resulting partition: {[0..0]x0..3],[1..1]x[0..3],[2..2]x[0..3], [3..3]x[0..3]}

Parameters

domain

Domain to partition.

Member Function Documentation

contained_in()

template<typename Dom >

template<typename ODom , typename MFG >

std::vector<std::pair<domain_type,bool> > stapl::rows_partition< Dom >::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 it is fully contained, False: if it is partially included). The returned collection contains elements for the partitions that contain elements on the given domain.

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.
