DisplayObjectChildren<T extends DisplayObject> class

This class is returned by the DisplayObjectParent.children getter.

It implements an Iterable of display objects and therefore allows an easy iteration over the children of a DisplayObjectParent.

Properties

iterator → Iterator<T>
Returns a new Iterator that allows iterating the elements of this Iterable. [...]
read-only
parent → DisplayObjectParent<DisplayObject>
final
reversed → Iterable<T>
read-only
first → T
Returns the first element.
read-only, inherited
hashCode → int
The hash code for this object.
read-only, inherited
isEmpty → bool
Returns true if there are no elements in this collection.
read-only, inherited
isNotEmpty → bool
Returns true if there is at least one element in this collection.
read-only, inherited
last → T
Returns the last element.
read-only, inherited
length → int
Returns the number of elements in this.
read-only, inherited
runtimeType → Type
A representation of the runtime type of the object.
read-only, inherited
single → T
Checks that this iterable has only one element, and returns that element.
