Methods

cast<R>() → KtList<R>

Available on KtList<T>, provided by the KtListExtensions extension

Provides a view of this KtList as an list of R instances.
dropLast(int n) → KtList<T>

Available on KtList<T>, provided by the KtListExtensions extension

Returns a list containing all elements except last n elements.
dropLastWhile(bool predicate(T)) → KtList<T>

Available on KtList<T>, provided by the KtListExtensions extension

Returns a list containing all elements except last elements that satisfy the given predicate.
elementAt(int index) → T

Available on KtList<T>, provided by the KtListExtensions extension

Returns an element at the given index or throws an IndexOutOfBoundsException if the index is out of bounds of this list.
elementAtOrElse(int index, T defaultValue(int index)) → T

Available on KtList<T>, provided by the KtListExtensions extension

Returns an element at the given index or the result of calling the defaultValue function if the index is out of bounds of this list.
elementAtOrNull(int index) → T?

Available on KtList<T>, provided by the KtListExtensions extension

Returns an element at the given index or null if the index is out of bounds of this collection.
first([bool predicate(T)?]) → T

Available on KtList<T>, provided by the KtListExtensions extension

Returns first element.
foldRight<R>(R initial, R operation(T, R acc)) → R

Available on KtList<T>, provided by the KtListExtensions extension

Accumulates value starting with initial value and applying operation from right to left to each element and current accumulator value.
foldRightIndexed<R>(R initial, R operation(int index, T, R acc)) → R

Available on KtList<T>, provided by the KtListExtensions extension

Accumulates value starting with initial value and applying operation from right to left to each element with its index in the original list and current accumulator value. @param operation function that takes the index of an element, the element itself and current accumulator value, and calculates the next accumulator value.
getOrElse(int index, T defaultValue(int)) → T

Available on KtList<T>, provided by the KtListExtensions extension

Returns an element at the given index or the result of calling the defaultValue function if the index is out of bounds of this list.
getOrNull(int index) → T?

Available on KtList<T>, provided by the KtListExtensions extension

Returns an element at the given index or null if the index is out of bounds of this list.
last([bool predicate(T)?]) → T

Available on KtList<T>, provided by the KtListExtensions extension

Returns the last element matching the given predicate. @throws NoSuchElementException if no such element is found.
reduceRight<S>(S operation(T, S acc)) → S

Available on KtList<T>, provided by the KtListExtensions extension

Accumulates value starting with last element and applying operation from right to left to each element and current accumulator value.
reduceRightIndexed<S>(S operation(int index, T, S acc)) → S

Available on KtList<T>, provided by the KtListExtensions extension

Accumulates value starting with last element and applying operation from right to left to each element with its index in the original list and current accumulator value. @param operation function that takes the index of an element, the element itself and current accumulator value, and calculates the next accumulator value.
single([bool predicate(T)?]) → T

Available on KtList<T>, provided by the KtListExtensions extension

Returns the single element matching the given predicate, or throws an exception if the list is empty or has more than one element.
singleOrNull([bool predicate(T)?]) → T?

Available on KtList<T>, provided by the KtListExtensions extension

Returns the single element matching the given predicate, or null if element was not found or more than one element was found.
slice(KtIterable<int> indices) → KtList<T>

Available on KtList<T>, provided by the KtListExtensions extension

Returns a list containing elements at specified indices.
takeLast(int n) → KtList<T>

Available on KtList<T>, provided by the KtListExtensions extension

Returns a list containing last n elements.
takeLastWhile(bool predicate(T)) → KtList<T>

Available on KtList<T>, provided by the KtListExtensions extension

Returns a list containing last elements satisfying the given predicate.
