abstract override fun clear()

fun <T, O> List<Observable<T>>.combineLatest(collector: (List<T>) -> O): Observable<Option<O>>

Collects the latest values emitted by a list of Observables and transforms them into a new Observable using the provided collector function.

abstract operator override fun contains(element: Node<T>): Boolean

abstract override fun containsAll(elements: Collection<Node<T>>): Boolean

findExtremeCoordsOnX

fun <V : Vector2D<V>> List<V>.findExtremeCoordsOnX(): ClosedRange<Double>

Given a non-empty list of points represented as vectors, this method finds the extreme coordinates (i.e. min and max coordinates) on the X-axis, these are used to create the returned ClosedRange.

findExtremeCoordsOnY

fun <V : Vector2D<V>> List<V>.findExtremeCoordsOnY(): ClosedRange<Double>

Given a non-empty list of points represented as vectors, this method finds the extreme coordinates (i.e. min and max coordinates) on the Y-axis, these are used to create the returned ClosedRange.

abstract override fun listIterator(): MutableListIterator<Node<T>>

abstract override fun listIterator(index: Int): MutableListIterator<Node<T>>

fun <R> Iterable<R>.randomElement(randomGenerator: RandomGenerator): R

Returns a random element of the Iterable using the provided randomGenerator.

@IgnorableReturnValue

@IgnorableReturnValue

abstract override fun removeAll(elements: Collection<Node<T>>): Boolean

@IgnorableReturnValue

abstract fun removeAt(index: Int): Node<T>

fun <T> List<T>.takeFraction(percentage: Double): List<T>

Takes the first percentage * size elements of the list.

toObservableList

fun <T> List<T>.toObservableList(): ObservableMutableList<T>

Converts the current list into an observable mutable list.

toObservableSet

fun <T> List<T>.toObservableSet(): ObservableMutableSet<T>
