Functions

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

abstract fun add(index: Int, element: Node<T>)

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

abstract fun addAll(index: Int, elements: Collection<Node<T>>): Boolean

abstract override fun clear()

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 operator fun get(index: Int): Node<T>

abstract fun indexOf(element: Node<T>): Int

abstract override fun isEmpty(): Boolean

abstract operator override fun iterator(): Iterator<Node<T>>

abstract fun lastIndexOf(element: Node<T>): Int

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.

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

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

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

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

abstract operator fun set(index: Int, element: Node<T>): Node<T>

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

Fisher–Yates shuffle algorithm using a RandomGenerator. More information on Wikipedia.
