RBushBox class

Bounding box for an r-tree item.

If your item class extends this one, writing toBBox function would be easier. Also it's got some useful methods like contains and area.

Implementers

Constructors

RBushBox({double minX = double.infinity, double minY = double.infinity, double maxX = double.negativeInfinity, double maxY = double.negativeInfinity})

Methods

contains(RBushBox b) → bool

distanceSq(double x, double y) → double

Calculates squared distance from (x, y) to this box.

enlargedArea(RBushBox b) → double

Calculates area for an extendes bounding box that would cover both this one and b. See extend for the extension method.

extend(RBushBox b) → dynamic

Extends this box's bounds to cover b.

intersectionArea(RBushBox b) → double

Calculates area for an intersection box of this and b.

intersects(RBushBox b) → bool

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

override

Operators

operator ==(Object other) → bool

The equality operator.
