Int16List abstract class

A fixed-length list of 16-bit signed integers that is viewable as a TypedData.

For long lists, this implementation can be considerably more space- and time-efficient than the default List implementation.

Integers stored in the list are truncated to their low 16 bits, interpreted as a signed 16-bit two's complement integer with values in the range -32768 to +32767.

Implements

List<int>
TypedData

Constants

BYTES_PER_ELEMENT → int: 2

Constructors

Int16List(int length) factory: Creates an Int16List of the specified length (in elements), all of whose elements are initially zero.
Int16List.fromList(List<int> elements) factory: Creates a Int16List with the same length as the elements list and copies over the elements.
Int16List.view(ByteBuffer buffer, [ int offsetInBytes = 0, int length ]) factory: Creates an Int16List view of the specified region in buffer.

isNotEmpty → bool read-only, inherited: Returns true if there is at least one element in this collection.
iterator → Iterator<int> read-only, inherited: Returns a new Iterator that allows iterating the elements of this Iterable.
last → int read-only, inherited: Returns the last element.
length → int read / write, inherited: Returns the number of objects in this list.
lengthInBytes → int read-only, inherited: Returns the length of this view, in bytes.
offsetInBytes → int read-only, inherited: Returns the offset in bytes into the underlying byte buffer of this view.
reversed → Iterable<int> read-only, inherited: Returns an Iterable of the objects in this list in reverse order.
runtimeType → Type read-only, inherited: A representation of the runtime type of the object.
single → int read-only, inherited: Checks that this iterable has only one element, and returns that element.

Operators

operator ==(other) → bool inherited: The equality operator.
operator [](int index) → int inherited: Returns the object at the given index in the list or throws a RangeError if index is out of bounds.
operator []=(int index, int value) → void inherited: Sets the value at the given index in the list to value or throws a RangeError if index is out of bounds.

insertAll(int index, Iterable<int> iterable) → void inherited: Inserts all objects of iterable at position index in this list.
join([String separator = "" ]) → String inherited: Converts each element to a String and concatenates the strings.
lastIndexOf(int element, [ int start ]) → int inherited: Returns the last index of element in this list.
lastWhere(bool test(E element), { int orElse() }) → int inherited: Returns the last element that satisfies the given predicate test.
map<T>(T f(E e)) → Iterable<T> inherited: Returns a new lazy Iterable with elements that are created by calling f on each element of this Iterable in iteration order.
noSuchMethod(Invocation invocation) → dynamic inherited: Invoked when a non-existent method or property is accessed.
reduce(int combine(E value, E element)) → int inherited: Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.
remove(Object value) → bool inherited: Removes the first occurrence of value from this list.
removeAt(int index) → int inherited: Removes the object at position index from this list.
removeLast() → int inherited: Pops and returns the last object in this list.
removeRange(int start, int end) → void inherited: Removes the objects in the range start inclusive to end exclusive.
removeWhere(bool test(E element)) → void inherited: Removes all objects from this list that satisfy test.
replaceRange(int start, int end, Iterable<int> replacement) → void inherited: Removes the objects in the range start inclusive to end exclusive and inserts the contents of replacement in its place.
retainWhere(bool test(E element)) → void inherited: Removes all objects from this list that fail to satisfy test.
setAll(int index, Iterable<int> iterable) → void inherited: Overwrites objects of this with the objects of iterable, starting at position index in this list.
setRange(int start, int end, Iterable<int> iterable, [ int skipCount = 0 ]) → void inherited: Copies the objects of iterable, skipping skipCount objects first, into the range start, inclusive, to end, exclusive, of the list.
shuffle([Random random ]) → void inherited: Shuffles the elements of this list randomly.
singleWhere(bool test(E element)) → int inherited: Returns the single element that satisfies test.
