ImmutablePartCollection class final
Represents immutable collection of parts for a polygon or polyline geometry. Each part is a collection of segments.
Polygons and polyline can have multiple disjoint parts. Each part is represented by an ImmutablePart. A part is composed of segments representing the edge of the polygon or polyline.

Methods
-
any(
bool test(ImmutablePart element)) → bool -
Checks whether any element of this iterable satisfies
test.inherited -
cast<
R> () → Iterable< R> -
A view of this iterable as an iterable of
Rinstances.inherited -
contains(
Object? element) → bool -
Whether the collection contains an element equal to
element.inherited -
elementAt(
int index) → ImmutablePart -
Returns the
indexth element.inherited -
every(
bool test(ImmutablePart element)) → bool -
Checks whether every element of this iterable satisfies
test.inherited -
expand<
T> (Iterable< T> toElements(ImmutablePart element)) → Iterable<T> -
Expands each element of this Iterable into zero or more elements.
inherited
-
firstWhere(
bool test(ImmutablePart element), {ImmutablePart orElse()?}) → ImmutablePart -
The first element that satisfies the given predicate
test.inherited -
fold<
T> (T initialValue, T combine(T previousValue, ImmutablePart element)) → T -
Reduces a collection to a single value by iteratively combining each
element of the collection with an existing value
inherited
-
followedBy(
Iterable< ImmutablePart> other) → Iterable<ImmutablePart> -
Creates the lazy concatenation of this iterable and
other.inherited -
forEach(
void action(ImmutablePart element)) → void -
Invokes
actionon each element of this iterable in iteration order.inherited -
getPart(
{required int index}) → ImmutablePart - Returns a part at the specified index in the immutable part collection. A part is represented by an immutable collection of segments.
-
indexOf(
ImmutablePart immutablePart) → int - Retrieves the position of the given part in the immutable part collection.
-
join(
[String separator = ""]) → String -
Converts each element to a String and concatenates the strings.
inherited
-
lastWhere(
bool test(ImmutablePart element), {ImmutablePart orElse()?}) → ImmutablePart -
The last element that satisfies the given predicate
test.inherited -
map<
T> (T toElement(ImmutablePart 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(
ImmutablePart combine(ImmutablePart value, ImmutablePart element)) → ImmutablePart -
Reduces a collection to a single value by iteratively combining elements
of the collection using the provided function.
inherited

countfirst elements of this iterable.inherited -
takeWhile(
bool test(ImmutablePart value)) → Iterable< ImmutablePart> -

inherited
-
toSet(
) → Set< ImmutablePart> -
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(ImmutablePart element)) → Iterable< ImmutablePart> -
