Constructors

new AttachedEvent(String name) #

AttachedEvent(String name) : super(name);

Properties

final String name #

inherited from Attachable
final String name;

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

GlobalId addHandler(AttachableObject obj, Action1 handler) #

GlobalId addHandler(AttachableObject obj, Action1<T> handler) {
  return obj._addHandler(this, handler);
}

new Attachable(String name) #

inherited from Attachable
Attachable(this.name);

new AttachedEvent(String name) #

AttachedEvent(String name) : super(name);

void fireEvent(AttachableObject obj, T args) #

void fireEvent(AttachableObject obj, T args) => obj._fireEvent(this, args);

abstract int hashCode() #

inherited from Hashable

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.

docs inherited from Object

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();

bool removeHandler(AttachableObject obj, GlobalId handlerId) #

bool removeHandler(AttachableObject obj, GlobalId handlerId) {
  requireArgumentNotNull(obj, 'obj');
  return obj._removeHandler(this, handlerId);
}

String toString() #

inherited from Object

Returns a string representation of this object.

external String toString();
