JointEdge class

A joint edge is used to connect bodies and joints together in a joint graph where each body is a node and each joint is an edge. A joint edge belongs to a doubly linked list maintained in each attached body. Each joint has two joint nodes, one for each attached body.

class JointEdge {
  /**
   * Constructs a new joint edge with everything set to null.
   */
  JointEdge() { }

  /**
   * Provides quick access to the other body attached.
   */
  Body other;

  /**
   * The joint.
   */
  Joint joint;

  /**
   * The previous joint edge in the body's joint list.
   */
  JointEdge prev;

  /**
   * The next joint edge in the body's joint list.
   */
  JointEdge next;
}

Constructors

new JointEdge() #

Constructs a new joint edge with everything set to null.

JointEdge() { }

Properties

Joint joint #

The joint.

Joint joint;

JointEdge next #

The next joint edge in the body's joint list.

JointEdge next;

Body other #

Provides quick access to the other body attached.

Body other;

JointEdge prev #

The previous joint edge in the body's joint list.

JointEdge prev;

final Type runtimeType #

inherited from Object

A representation of the runtime type of the object.

external Type get runtimeType;

Operators

bool operator ==(other) #

inherited from Object

The equality operator.

The default behavior for all Objects 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

int hashCode() #

inherited from Object

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();

new JointEdge() #

Constructs a new joint edge with everything set to null.

JointEdge() { }

noSuchMethod(String name, List args) #

inherited from Object

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() #

inherited from 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() #

inherited from Object

Returns a string representation of this object.

external String toString();
