GpsPointsCollection<T extends GpsPoint> class
abstract
Stores GPS points with read/write access.
Provides read/write access to GPS points. Because lightweight GpsPointsViews may be created on the data in the list, adding is the only modification operation that's allowed, as inserting or removing could lead to invalid views. Subclass names may start with "Gpc".

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
-
Collections are typically not read-only.
no setteroverride
-
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.
no setterinherited
- 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
- sortingEnforcement ↔ SortingEnforcement
-
Whether the list is will disallow modifications that render it
in a state that's not sorted by time. Setting this property to true
while the collection is in an unsorted state will raise an exception.

Methods
-
add(
T element) → bool -
Add a single
element
to the collection. -
add_Unsafe(
T element) → void - Internal implementation of add, which does not do any safety checks regarding sorting. Only to be overridden in children.
-
addAll(
Iterable< T> source) → void -
addAllStartingAt(
Iterable< T> source, [int skipItems = 0, int? nrItems]) → void -
Add all elements from
source
to this, after skippingskipItems
items from thesource
.skipItems
=0 is equivalent to calling addAll. -
addAllStartingAt_Unsafe(
Iterable< T> source, [int skipItems = 0, int? nrItems]) → void - Internal implementation of addAllStartingAt, which does not do any safety checks regarding sorting. Only to be overridden in children.
-
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 -
checkContentsSortedByTime(
[int skipItems = 0, int? nrItems]) → bool - Checks whether the contents are sorted by increasing time in cases where the list is not marked as sortedByTime.
-
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 -
getSubSource(
Iterable< T> source, int skipItems, int? nrItems) → Iterable<T> -
Returns a subset iterable from
source
that skipsskipItems
and copies up tonrItems
(if specified) or the entire list (if not specified). -
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.inherited -
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
-
rollbackAddingLastItem(
) → dynamic - Removes the last object in this list, but only intended for use during add and similar calls. The list is in general not supposed to have insert/remove operations available as explained in the documentation of the list itself.

containing the elements between
start

Creates a lazy iterable of the
count
first elements of this iterable.inherited -

bool test(T value)) → Iterable< T> -
Creates a lazy iterable of the leading elements satisfying
test
.inherited -
toList(
{bool growable = true}) → List< T> -
