Float32List class

A fixed-length list of IEEE 754 single-precision binary floating-point numbers that is viewable as a TypedData.

A fixed-length list of IEEE 754 single-precision binary floating-point numbers that is viewable as a TypedData.

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

Implements

Constructors

Float32List(int length)
Creates a Float32List of the specified length (in elements), all of whose elements are initially zero.
Float32List.fromList(List<double> elements)
Creates a Float32List with the same length as the elements list and copies over the elements.
Float32List.view(ByteBuffer buffer, [int offsetInBytes = 0, int length])
Creates a Float32List view of the specified region in buffer.

Instance Methods

insert(int index, double element) → void Inherited
Inserts the object at position index in this list.
clear() → void Inherited
Removes all objects from this list; the length of the list becomes zero.
take(int n) → Iterable<double> Inherited
Returns a lazy iterable of the count first elements of this iterable.
map(dynamic f(E element)) → Iterable Inherited
Returns a new lazy Iterable with elements that are created by calling f on each element of this Iterable in iteration order.
toSet() → Set<double> Inherited
Creates a Set containing the same elements as this iterable.
forEach(void f(E element)) → void Inherited
Applies the function f to each element of this collection in iteration order.
setAll(int index, Iterable<double> iterable) → void Inherited
Overwrites objects of this with the objects of iterable, starting at position index in this list.
skipWhile(bool test(E value)) → Iterable<double> Inherited
Returns an Iterable that skips leading elements while test is satisfied.
asMap() → Map<int,double> Inherited
Returns an unmodifiable Map view of this.
setRange(int start, int end, Iterable<double> 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.
join([String separator = ""]) → String Inherited
Converts each element to a String and concatenates the strings.
lastWhere(bool test(E element), {E orElse()}) → double Inherited
Returns the last element that satisfies the given predicate test.
shuffle([Random random]) → void Inherited
Shuffles the elements of this list randomly.
reduce(E combine(E value, E element)) → double Inherited
Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.
any(bool f(E element)) → bool Inherited
Checks whether any element of this iterable satisfies test.
every(bool f(E element)) → bool Inherited
Checks whether every element of this iterable satisfies test.
where(bool f(E element)) → Iterable<double> Inherited
Returns a new lazy Iterable with all elements that satisfy the predicate test.
sort([int compare(E a, E b)]) → void Inherited
Sorts this list according to the order specified by the compare function.
skip(int n) → Iterable<double> Inherited
Returns an Iterable that provides all but the first count elements.
expand(Iterable f(E element)) → Iterable Inherited
Expands each element of this Iterableinto zero or more elements.
indexOf(double element, [int start = 0]) → int Inherited
Returns the first index of element in this list.
elementAt(int index) → double Inherited
Returns the indexth element.
remove(Object value) → bool Inherited
Removes the first occurence of value from this list.
getRange(int start, int end) → Iterable<double> Inherited
Returns an Iterable that iterates over the objects in the range start inclusive to end exclusive.
removeAt(int index) → double Inherited
Removes the object at position index from this list.
takeWhile(bool test(E value)) → Iterable<double> Inherited
Returns a lazy iterable of the leading elements satisfying test.
removeRange(int start, int end) → void Inherited
Removes the objects in the range start inclusive to end exclusive.
fold(initialValue, dynamic combine(previousValue, E element)) → dynamic Inherited
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
sublist(int start, [int end]) → List<double> Inherited
Returns a new list containing the objects from start inclusive to end exclusive.
firstWhere(bool test(E element), {E orElse()}) → double Inherited
Returns the first element that satisfies the given predicate test.
contains(Object element) → bool Inherited
Returns true if the collection contains an element equal to element.
add(double value) → void Inherited
Adds value to the end of this list, extending the length by one.
singleWhere(bool test(E element)) → double Inherited
Returns the single element that satisfies test.
lastIndexOf(double element, [int start]) → int Inherited
Returns the last index of element in this list.
replaceRange(int start, int end, Iterable<double> replacement) → void Inherited
Removes the objects in the range start inclusive to end exclusive and inserts the contents of replacement in its place.
addAll(Iterable<double> iterable) → void Inherited
Appends all objects of iterable to the end of this list.
insertAll(int index, Iterable<double> iterable) → void Inherited
Inserts all objects of iterable at position index in this list.
removeWhere(bool test(E element)) → void Inherited

Operators

operator []=(int index, double value) → void Inherited
