-
The hash code for this object.
no setterinherited
- isDisposed → bool
-
Whether this wrapper has been disposed.
no setterinherited

-
Whether this collection has no elements.
no setterinherited
- isNotEmpty → bool
-
Whether this collection has at least one element.
no setterinherited

iterator
→ Iterator<
KeyPoint> -
A new
Iteratorthat allows iterating the elements of thisIterable.no setteroverride - last → KeyPoint
-
The last element.
no setterinherited

-
The number of elements in this Iterable.

getter/setter pairinherited
- ref → VecKeyPoint
-
no setteroverride

Methods
-
add(
KeyPoint element) → void -
override
-
any(
bool test(KeyPoint element)) → bool -
Checks whether any element of this iterable satisfies
test.inherited -
asVoid(
) → Pointer< Void> -
override
-
cast<
R> () → Iterable< R> -
A view of this iterable as an iterable of
Rinstances.inherited -
clear(
) → void -
override
-
clone(
) → VecKeyPoint -
override
-
contains(
Object? element) → bool -
Whether the collection contains an element equal to
element.inherited -
dispose(
) → void -
Releases the underlying native resources. Idempotent: calling it more
than once is safe, but the wrapper must not be used after dispose.
inherited
-
elementAt(
int index) → KeyPoint -
Returns the
indexth element.inherited -
every(
bool test(KeyPoint element)) → bool -
Checks whether every element of this iterable satisfies
test.inherited -
expand<
T> (Iterable< T> toElements(KeyPoint element)) → Iterable<T> -
Expands each element of this Iterable into zero or more elements.
inherited
-
extend(
Vec< Struct, dynamic> other) → void -
override
-
firstWhere(
bool test(KeyPoint element), {KeyPoint orElse()?}) → KeyPoint -
The first element that satisfies the given predicate
test.inherited -
fold<
T> (T initialValue, T combine(T previousValue, KeyPoint element)) → T -
Reduces a collection to a single value by iteratively combining each
element of the collection with an existing value
inherited
-
followedBy(
Iterable< KeyPoint> other) → Iterable<KeyPoint> -
Creates the lazy concatenation of this iterable and
other.inherited -
forEach(
void action(KeyPoint element)) → void -
Invokes
actionon each element of this iterable in iteration order.inherited -
freeNative(
) → void -
Frees the native resources owned by this wrapper. Subclasses implement the
concrete free logic here; callers must use dispose instead.
override
-
join(
[String separator = ""]) → String -
Converts each element to a String and concatenates the strings.
inherited
-
lastWhere(
bool test(KeyPoint element), {KeyPoint orElse()?}) → KeyPoint -
The last element that satisfies the given predicate
test.inherited -
map<
T> (T toElement(KeyPoint e)) → Iterable< T> -
The current elements of this iterable modified by
toElement.inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
reduce(
KeyPoint combine(KeyPoint value, KeyPoint element)) → KeyPoint -
Reduces a collection to a single value by iteratively combining elements
of the collection using the provided function.
inherited
-
reserve(
int newCapacity) → void -
override
-
resize(
int newSize) → void -
override
-
shrinkToFit(
) → void -
override
-
singleWhere(
bool test(KeyPoint element), {KeyPoint orElse()?}) → KeyPoint -
The single element that satisfies
test.inherited -
size(
) → int -
override
-
skip(
int count) → Iterable< KeyPoint> -
Creates an Iterable that provides all but the first
countelements.inherited -
skipWhile(
bool test(KeyPoint element)) → Iterable< KeyPoint> -
Creates an
Iterablethat skips leading elements whiletestis satisfied.inherited -
take(
int count) → Iterable< KeyPoint> -
Creates a lazy iterable of the
countfirst elements of this iterable.inherited -
takeWhile(
bool test(KeyPoint element)) → Iterable< KeyPoint> -
Creates a lazy iterable of the leading elements satisfying
test.inherited -
toList(
{bool growable = true}) → List< KeyPoint> -
Creates a List containing the elements of this Iterable.
inherited
-
toSet(
) → Set< KeyPoint> -
Creates a Set containing the same elements as this iterable.
inherited
-
toString(
) → String -
Returns a string representation of (some of) the elements of
this.inherited -
where(
bool test(KeyPoint element)) → Iterable< KeyPoint> -
Creates a new lazy Iterable with all elements that satisfy the
predicate
test.inherited -
whereType<
T> () → Iterable< R> -
Creates a new lazy Iterable with all elements that have type
T.inherited
Operators
