Properties
- first → T
-
The first element.
no setterinherited
- hashCode → int
-
The hash code for this object.
no setterinherited
- isEmpty → bool
-
Whether this collection has no elements.
no setterinherited
- isNotEmpty → bool
-
Whether this collection has at least one element.
no setterinherited
- isReadonly → bool
-
Indicate if the view is read-only and cannot be modified.
no setterinherited
-
iterator
→ RandomAccessIterator<
T> -
A new
Iterator
that allows iterating the elements of thisIterable
.no setterinherited - last → T
-
The last element.
no setterinherited
- length → int
-
The number of elements in this Iterable.
no setteroverride
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- single → T
-
Checks that this iterable has only one element, and returns that element.
no setterinherited
- sortedByTime → bool
-
Indicates whether the contents are sorted in increasing order of time
value. If this is the case, time-based queries can be faster by performing
a binary search. For every point in time only one entity is allowed to
provide a location value, i.e. a list is not sorted if it contains two
identical elements consecutively.
no setteroverride
Methods
-
any(
bool test(T 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
R
instances.inherited -
compareElementTime(
int elementNrA, int elementNrB) → TimeComparisonResult -
Performs compareTime for the elements in the positions
elementNrA
andelementNrB
, then returns the result.inherited -
compareElementTimeWithSeparateItem(
int elementNrA, T elementB) → TimeComparisonResult -
Performs compareTime for the item in the positions
elementNrA
and some separateelementB
that's presumably not in the list, then returns the result.inherited -
compareElementTimeWithSeparateTime(
int elementNrA, GpsTime timeB) → TimeComparisonResult -
Performs compareTime for the item in the positions
elementNrA
and some separatetimeB
that's presumably not in the list, then returns the result.inherited -
contains(
Object? element) → bool -
Whether the collection contains an element equal to
element
.inherited -
diffElementTimeAndSeparateTime(
int elementNrA, GpsTime timeB) → int -
Calculate the difference in time between the item in the position
elementNrA
and thetimeB
. See diffTime for explanations on how the difference is calculated and when it is positive, negative or zero.inherited -
elementAt(
int index) → T -
Returns the
index
th element.inherited -
every(
bool test(T element)) → bool -
Checks whether every element of this iterable satisfies
test
.inherited -
expand<
T> (Iterable< T> toElements(T element)) → Iterable<T> -
Expands each element of this Iterable into zero or more elements.
inherited
-
firstWhere(
bool test(T element), {T orElse()?}) → T -
The first element that satisfies the given predicate
test
.inherited -
fold<
T> (T initialValue, T combine(T previousValue, T element)) → T -
Reduces a collection to a single value by iteratively combining each
element of the collection with an existing value
inherited
-
followedBy(
Iterable< T> other) → Iterable<T> -
Creates the lazy concatenation of this iterable and
other
.inherited -
forEach(
void action(T element)) → void -
Invokes
action
on each element of this iterable in iteration order.inherited -
join(
[String separator = ""]) → String -
Converts each element to a String and concatenates the strings.
inherited
-
lastWhere(
bool test(T element), {T orElse()?}) → T -
The last element that satisfies the given predicate
test
.inherited -
map<
T> (T toElement(T e)) → Iterable< T> -
The current elements of this iterable modified by
toElement
.inherited -
newEmpty(
{int? capacity}) → GpsPointsView< T> -
Creates a collection of the same type as this, optionally with
a starting
capacity
for children that support that.override -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
reduce(
T combine(T value, T element)) → T -
Reduces a collection to a single value by iteratively combining elements
of the collection using the provided function.
inherited
-
singleWhere(
bool test(T element), {T orElse()?}) → T -
The single element that satisfies
test
.inherited -
skip(
int count) → RandomAccessIterable< T> -
Creates an Iterable that provides all but the first
count
elements.inherited -
skipWhile(

Iterable
that skips leading elements whiletest
is satisfied.inherited -
sublist(
int start, [int? end]) → GpsPointsView< T> -
Returns a new collection of the same type as the current collection
containing the elements between
start
andend
.override -
take(
int count) → RandomAccessIterable< T> -
Creates a lazy iterable of the
count
first elements of this iterable.inherited -
takeWhile(
