BaseSpringSystem class

BaseSpringSystem maintains the set of springs within an Application context. It is responsible for Running the spring integration loop and maintains a registry of all the Springs it solves for. In addition to listening to physics events on the individual Springs in the system, listeners can be added to the BaseSpringSystem itself to provide pre and post integration setup.

Implementers

• SpringSystem

Constructors

BaseSpringSystem(SpringLooper springLooper)

create a new BaseSpringSystem @param springLooper parameterized springLooper to allow testability of the physics loop

Properties

hashCode → int

The hash code for this object.

no setter, inherited

mSpringLooper ↔ SpringLooper

late, final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

activateSpring(String springId) → void

This is used internally by the {@link Spring}s created by this {@link BaseSpringSystem} to notify it has reached a state where it needs to be iterated. This will add the spring to the list of active springs on this system and start the iteration if the system was idle before this call. @param springId the id of the Spring to be activated

addListener(SpringSystemListener newListener) → void

Add new listener object. @param newListener listener

advance(double deltaTime) → void

update the springs in the system @param deltaTime delta since last update in millis

createSpring() → Spring

create a spring with a random uuid for its name. @return the spring

deregisterSpring(Spring spring) → void

Deregisters a Spring from this BaseSpringSystem, so it won't be iterated anymore. The Spring should not be used anymore after doing this.

getAllSprings() → List<Spring>

return all the springs in the simulator @return all the springs

getIsIdle() → bool

check if the system is idle @return is the system idle

getSpringById(String id) → Spring?

get a spring by name @param id id of the spring to retrieve @return Spring with the specified key

loop(double elapsedMillis) → void

loop the system until idle @param elapsedMillis elapsed milliseconds

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

registerSpring(Spring spring) → void

Registers a Spring to this BaseSpringSystem so it can be iterated if active. @param spring the Spring to register

removeAllListeners() → void

Remove all listeners.

removeListener(SpringSystemListener listenerToRemove) → void

Remove listener object. @param listenerToRemove listener

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
