ContactEdge class

A contact edge connects bodies and contacts together in a contact graph. Each body is a node in the graph and each contact is an edge. A contact edge is a part of a doubly linked list that is maintained in each attached body. Each contact has two contact nodes, one for each attached body.

class ContactEdge {
  /** The other body attached to the edge. */
  Body other;

  /** The contact. */
  Contact contact;

  /** The previous contact edge in the body's contact list. */
  ContactEdge prev;

  /** The next contact edge in the body's contact list. */
  ContactEdge next;

  /**
   * Constructs a new ContactEdge with all fields set to null.
   */
  ContactEdge() :
    other = null,
    contact = null,
    prev = null,
    next = null {}
}

Constructors

new ContactEdge() #

Constructs a new ContactEdge with all fields set to null.

ContactEdge() :
  other = null,
  contact = null,
  prev = null,
  next = null {}

Properties

Contact contact #

The contact.

Contact contact;

ContactEdge next #

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

ContactEdge next;

Body other #

The other body attached to the edge.

Body other;

ContactEdge prev #

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

ContactEdge 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

new ContactEdge() #

Constructs a new ContactEdge with all fields set to null.

ContactEdge() :
  other = null,
  contact = null,
  prev = null,
  next = null {}

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();

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();
