DynamicTreeNode class
This is a node for the DynamicTree.
class DynamicTreeNode { AxisAlignedBox box; DynamicTreeNode parent; DynamicTreeNode next; DynamicTreeNode childOne; DynamicTreeNode childTwo; /** * Can contain whatever is useful to the user. */ var userData; /** Used for sorting. */ int key; /** Should never be constructed outside the engine. */ DynamicTreeNode._construct() : box = new AxisAlignedBox(), parent = null, next = null, childOne = null, childTwo = null { } /** * Returns true if this node is a leaf. */ bool get isLeaf() => childOne == null; String toString() => box.toString(); }
Constructors
new DynamicTreeNode._construct() #
Should never be constructed outside the engine.

Properties
AxisAlignedBox box #
AxisAlignedBox box;
DynamicTreeNode childOne #
DynamicTreeNode childOne;
DynamicTreeNode childTwo #
DynamicTreeNode childTwo;
final bool isLeaf #
Returns true if this node is a leaf.
bool get isLeaf() => childOne == null;
int key #
Used for sorting.
int key;
DynamicTreeNode next #
DynamicTreeNode next;
DynamicTreeNode parent #
DynamicTreeNode parent;
final Type runtimeType #
A representation of the runtime type of the object.
external Type get runtimeType;
var userData #
Can contain whatever is useful to the user.
var userData;
Operators
bool operator ==(other) #
The equality operator.
The default behavior for all Object
s is to return true if and
only if this
and
other are the same object.
If a subclass overrides the equality operator it should override
the hashCode
method as well to maintain consistency.
bool operator ==(other) => identical(this, other);
Methods
new DynamicTreeNode._construct() #
Should never be constructed outside the engine.
DynamicTreeNode._construct() : box = new AxisAlignedBox(), parent = null, next = null, childOne = null, childTwo = null { }
int hashCode() #
Get a hash code for this object.
All objects have hash codes. Hash codes are guaranteed to be the
same for objects that are equal when compared using the equality
operator ==
. Other than that there are no guarantees about
the hash codes. They will not be consistent between runs and
there are no distribution guarantees.
If a subclass overrides hashCode
it should override the
equality operator as well to maintain consistency.
external int hashCode();
noSuchMethod(String name, List args) #
noSuchMethod
is invoked when users invoke a non-existant method
on an object. The name of the method and the arguments of the
invocation are passed to noSuchMethod
. If noSuchMethod
returns a value, that value becomes the result of the original
invocation.
The default behavior of noSuchMethod
is to throw a
noSuchMethodError
.
external Dynamic noSuchMethod(String name, List args);
const Object() #
Creates a new Object
instance.
Object
instances have no meaningful state, and are only useful
through their identity. An Object
instance is equal to itself
only.
const Object();
String toString() #
Returns a string representation of this object.
String toString() => box.toString();
