DefaultWorldPool class
Provides object pooling for some objects used in the engine. Objects retrieved from here should only be used temporarily.
class DefaultWorldPool { Collision collision; TimeOfImpact timeOfImpact; Distance distance; DefaultWorldPool() { distance = new Distance._construct(); collision = new Collision._construct(this); timeOfImpact = new TimeOfImpact._construct(this); } Queue<CircleContact> getCircleContactStack() { final queue = new Queue<CircleContact>(); for (int i = 0; i < Settings.CONTACT_STACK_INIT_SIZE; i++) { queue.addFirst(new CircleContact(this)); } return queue; } Queue<PolygonAndCircleContact> getPolyCircleContactStack() { final queue = new Queue<PolygonAndCircleContact>(); for (int i = 0; i < Settings.CONTACT_STACK_INIT_SIZE; i++) { queue.addFirst(new PolygonAndCircleContact(this)); } return queue; } Queue<PolygonContact> getPolyContactStack() { final queue = new Queue<PolygonContact>(); for (int i = 0; i < Settings.CONTACT_STACK_INIT_SIZE; i++) { queue.addFirst(new PolygonContact(this)); } return queue; } }
Constructors
new DefaultWorldPool() #
DefaultWorldPool() { distance = new Distance._construct(); collision = new Collision._construct(this); timeOfImpact = new TimeOfImpact._construct(this); }
Properties
final Type runtimeType #
A representation of the runtime type of the object.
external Type get runtimeType;
TimeOfImpact timeOfImpact #
TimeOfImpact timeOfImpact;
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 DefaultWorldPool() #
DefaultWorldPool() { distance = new Distance._construct(); collision = new Collision._construct(this); timeOfImpact = new TimeOfImpact._construct(this); }
Queue<CircleContact> getCircleContactStack() #
Queue<CircleContact> getCircleContactStack() { final queue = new Queue<CircleContact>(); for (int i = 0; i < Settings.CONTACT_STACK_INIT_SIZE; i++) { queue.addFirst(new CircleContact(this)); } return queue; }
Queue<PolygonAndCircleContact> getPolyCircleContactStack() #
Queue<PolygonAndCircleContact> getPolyCircleContactStack() { final queue = new Queue<PolygonAndCircleContact>(); for (int i = 0; i < Settings.CONTACT_STACK_INIT_SIZE; i++) { queue.addFirst(new PolygonAndCircleContact(this)); } return queue; }
Queue<PolygonContact> getPolyContactStack() #
Queue<PolygonContact> getPolyContactStack() { final queue = new Queue<PolygonContact>(); for (int i = 0; i < Settings.CONTACT_STACK_INIT_SIZE; i++) { queue.addFirst(new PolygonContact(this)); } return queue; }
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.
external String toString();
