TimeStep class

This is an internal structure.

class TimeStep {
  TimeStep() :
    dt = 0,
    inv_dt = 0,
    dtRatio = 0,
    velocityIterations = 0,
    positionIterations = 0,
    warmStarting = true { }

  /** time step */
  num dt;

  /** inverse time step (0 if dt == 0). */
  num inv_dt;

  /** dt * inv_dt0 */
  num dtRatio;

  int velocityIterations;

  int positionIterations;

  bool warmStarting;
}

Constructors

new TimeStep() #

TimeStep() :
  dt = 0,
  inv_dt = 0,
  dtRatio = 0,
  velocityIterations = 0,
  positionIterations = 0,
  warmStarting = true { }

Properties

num dt #

time step

num dt;

num dtRatio #

dt * inv_dt0

num dtRatio;

num inv_dt #

inverse time step (0 if dt == 0).

num inv_dt;

int positionIterations #

int positionIterations;

final Type runtimeType #

inherited from Object

A representation of the runtime type of the object.

external Type get runtimeType;

int velocityIterations #

int velocityIterations;

bool warmStarting #

bool warmStarting;

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();

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();

new TimeStep() #

TimeStep() :
  dt = 0,
  inv_dt = 0,
  dtRatio = 0,
  velocityIterations = 0,
  positionIterations = 0,
  warmStarting = true { }

String toString() #

inherited from Object

Returns a string representation of this object.

external String toString();
