Algorithm::SpatialIndex::Strategy::2D - Base class for 2D indexing strategies
use Algorithm::SpatialIndex; my $idx = Algorithm::SpatialIndex->new( strategy => 'QuadTree', );
This class acts as a base class for 2D indexing strategy implementations. It implements part of the strategy interface for two dimensions and provides some defaults that are useful for 2D indexes:
no_of_dimensionsreturns 2 (doh).
item_coord_typesdefaults to two doubles.
coord_typesdefaults to four doubles.
This Algorithm::SpatialIndex::Strategy subclass implements a generic
filter_items_in_rect method that assumes only two dimensions and that items have two coordinates (x, y).
