Returns the iterator pointing at the begin of the rtree values range.
This method returns the iterator which may be used to iterate over all values stored in the rtree.
template<
typename Value
,
typename Parameters
,
typename IndexableGetter
,
typename EqualTo
,
typename Allocator
>
rtree< Value, Parameters, IndexableGetter, EqualTo, Allocator >::const_iterator
begin
(
rtree< Value, Parameters, IndexableGetter, EqualTo, Allocator > const &
tree
)
The iterator pointing at the begin of the range.
std::for_each(bgi::begin(tree), bgi::end(tree), do_something()); // the same as std::for_each(boost::begin(tree), boost::end(tree), do_something());
ForwardIterator
If allocation throws.
