GpsPointsView<T extends GpsPoint> class Null safety

Read-only view on the GPS points stored in a GpsPointsCollection.

Provides read-only access to GPS points, therefore typically acting as a view onto a read/write collection of GpsPoints. Subclass names may start with "Gpv".

Properties

first → T
Returns the first element.
read-onlyinherited
hashCode int
The hash code for this object.
read-onlyinherited
isEmpty bool
Whether this collection has no elements.
read-onlyinherited
isNotEmpty bool
Whether this collection has at least one element.
read-onlyinherited
isReadonly bool
Indicate if the view is read-only and cannot be modified.
read-only
iterator → RandomAccessIterator<T>
Returns a new Iterator that allows iterating the elements of this Iterable.
read-onlyinherited
last → T
Returns the last element.
read-onlyinherited
length int
Returns the number of elements in this.
read-onlyinherited
runtimeType Type
A representation of the runtime type of the object.
read-onlyinherited
single → T
Checks that this iterable has only one element, and returns that element.
read-onlyinherited
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.

Methods

any(bool test(T element)) bool
Checks whether any element of this iterable satisfies test.
inherited
cast<R>() Iterable<R>
Provides 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 and elementNrB, then returns the result.
compareElementTimeWithSeparateItem(int elementNrA, T elementB) TimeComparisonResult
Performs compareTime for the item in the positions elementNrA and some separate elementB that's presumably not in the list, then returns the result.
compareElementTimeWithSeparateTime(int elementNrA, GpsTime timeB) TimeComparisonResult
Performs compareTime for the item in the positions elementNrA and some separate timeB that's presumably not in the list, then returns the result.
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 the timeB. See diffTime for explanations on how the difference is calculated and when it is positive, negative or zero.
elementAt(int index) → T
Returns the indexth 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
Returns 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>
Returns 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
Returns 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.
@protected
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent 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
Returns the single element that satisfies test.
inherited
skip(int count) → RandomAccessIterable<T>
Returns an Iterable that provides all but the first count elements.
inherited
skipWhile(bool test(T value)) Iterable<T>
Returns an Iterable that skips leading elements while test 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 and end.
take(int count) → RandomAccessIterable<T>
Returns a lazy iterable of the count first elements of this iterable.
inherited
takeWhile(bool test(T value)) Iterable<T>
Returns a lazy iterable of the leading elements satisfying test.
inherited
toList({bool growable = true}) List<T>
Creates a List containing the elements of this Iterable.
inherited
toSet() Set<T>
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(T element)) Iterable<T>
Returns a new lazy Iterable with all elements that satisfy the predicate test.
inherited
whereType<T>() Iterable<T>
Returns a new lazy Iterable with all elements that have type T.
