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 228 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.

Definition at line 715 of file Partitions.h.

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

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

  // recursive implementation
