Methods

clear() → void

Clear the Quadtree

getQuadrants(Rect object) → List<Quadrant>

Determines which quadrants the object belongs to.

insert(O object) → void

Insert the object into the node. If the node exceeds the capacity, it will split and add all objects to their corresponding subnodes.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a non-existent method or property is accessed.

inherited

retrieve(Rect bounds) → List<O>

Return all objects that could collide with the given object, given bounds.

retrieveAllNodes([Quadtree<O>? quadtree]) → List<Rect>

split() → void

Split the node into 4 subnodes (ne, nw, sw, se)

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object o) → bool

The equality operator.
