Constructor & Destructor Documentation

template<typename Data >

geo::part::PartitionContainer< Data >::PartitionContainer ( Area_t const &  area, Subpartitions_t &&  subpartitions, Data_t *  defData = nullptr  )

inlineprotected

Constructor: sets the partition.

Parameters

area	overall area covered
subpartitions	list of subpartitions (pointers)
defData	datum to be returned for points not covered by subpartitions

The subpartitions will be moved from the argument.

It is required and assumed that the subpartitions do not overlap and that the points covered by them are a subset of area. Neither of theses requirements is checked.

template<typename Pred >

void geo::part::Partition< Data >::walk ( Pred &&  pred ) const

inlineinherited

Applies pred to all partitions.

Template Parameters

Pred	a predicate type

Parameters

pred	the predicate to be applied

The predicate pred is applied to this partition first, and then to all subpartitions in no specified order.

The predicate is any object behaving like a unary function of signature:

void predicate(Partition<Data> const& part);

If the predicate returns a value, that value is ignored. The predicate is forwarded while "walking" through the partitions.

Definition at line 241 of file Partitions.h.

      {
        walk(this, pred);
      }

template<typename Data >

template<typename Pred >

void geo::part::Partition< Data >::walk ( Partition_t const *  start, Pred &&  pred  )

staticprotectedinherited

Applies pred to start partition first, and then to all subpartitions.

References geo::part::Partition< Data >::parts().

{
  if (!start) return;
  pred(*start);

  // recursive implementation
  for (auto const& subPart : start->parts())
