IntRange class - dev.anycode.dart.ranges library

Constructors

IntRange.new(num? start, num? end, {bool startInclusive = true, bool endInclusive = false}): Creates a new IntRange with the specified start and end values.

Properties

endInclusive → bool: no setterinherited
first → int: 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
iterator → Iterator<int>: Returns an iterator over the elements in this range. Throws an exception if the range is not discrete or is infinite.
no setteroverride
last → int: The last element.
no setterinherited
length → int: The number of elements in this Iterable.
no setterinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
single → int: Checks that this iterable has only one element, and returns that element.
no setterinherited
startInclusive → bool: no setterinherited

Methods

any(bool test(int 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
compareTo(Range<Comparable> other) → int: Compares this range to another range. First compare starts of the ranges. If start of this range is less than the start of the other, return -1, if it's greater, return 1. If both starts are equal, compare ends of the ranges.
inherited
contains(Object? obj) → bool: Detect whether this range contains an element.
inherited
elementAt(int index) → int: Returns the indexth element.
inherited
end({bool? inclusive}) → num?: If inclusive is provided and differs from the current end inclusion, the end value is adjusted to the next or previous value accordingly.
inherited
every(bool test(int element)) → bool: Checks whether every element of this iterable satisfies test.
inherited
except(Range<num> that) → List<Range<num>>: The difference between two ranges is the set of all elements that are in this range but not in the other range.
inherited
expand<T>(Iterable<T> toElements(int element)) → Iterable<T>: Expands each element of this Iterable into zero or more elements.
inherited
firstWhere(bool test(int element), {int orElse()?}) → int: The first element that satisfies the given predicate test.
inherited
fold<T>(T initialValue, T combine(T previousValue, int element)) → T: Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
inherited
followedBy(Iterable<int> other) → Iterable<int>: Creates the lazy concatenation of this iterable and other.
inherited
forEach(void action(int element)) → void: Invokes action on each element of this iterable in iteration order.
inherited
intersect(Range<num> that) → Range<num>?: The intersection of two ranges is the set of all elements that are in both ranges.
inherited
isAdjacentTo(Range<num> that) → bool: Test whether this range is adjacent to another range. The ranges are adjacent if the end of this range is the same as the start of the other range or vice versa.
inherited
isSubsetOf(Range<num> that, {bool strict = false}) → bool: Evaluate whether this range is a subset of another.
inherited
isSupersetOf(Range<num> that, {bool strict = false}) → bool: Evaluate whether this range is a superset of another.
inherited
join([String separator = ""]) → String: Converts each element to a String and concatenates the strings.
inherited
lastWhere(bool test(int element), {int orElse()?}) → int: The last element that satisfies the given predicate test.
inherited
map<T>(T toElement(int e)) → Iterable<T>: The current elements of this iterable modified by toElement.
inherited
newInstance() → IntRange: Creates a new empty instance of the range.
override
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
overlaps(Range<num> that) → bool: Check whether this range overlaps with another range.
inherited
reduce(int combine(int value, int element)) → int: Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.
inherited
singleWhere(bool test(int element), {int orElse()?}) → int: The single element that satisfies test.
inherited
skip(int count) → Iterable<int>: Creates an Iterable that provides all but the first count elements.
inherited
skipWhile(bool test(int value)) → Iterable<int>: Creates an Iterable that skips leading elements while test is satisfied.
inherited
start({bool? inclusive}) → num?: If inclusive is provided and differs from the current start inclusion, the start value is adjusted to the next or previous value accordingly.
inherited
take(int count) → Iterable<int>: Creates a lazy iterable of the count first elements of this iterable.
inherited
takeWhile(bool test(int value)) → Iterable<int>: Creates a lazy iterable of the leading elements satisfying test.
inherited
toList({bool growable = true}) → List<int>: Creates a List containing the elements of this Iterable.
inherited
toSet() → Set<int>: Creates a Set containing the same elements as this iterable.
inherited
toString() → String: A string representation of this object.
inherited
union(Range<num> that) → List<Range<num>>: The union of two ranges is the set of all elements that are in either range.
inherited
where(bool test(int element)) → Iterable<int>: Creates a new lazy Iterable with all elements that satisfy the predicate test.
inherited
whereType<T>() → Iterable<T>: Creates a new lazy Iterable with all elements that have type T.
inherited

Operators

operator *(Range<num> that) → Range<num>?: Operator for the intersection of this range and another range.
inherited
operator +(Range<num> that) → List<Range<num>>: Operator for the union of this range and another range.
inherited
operator -(Range<num> that) → List<Range<num>>: Operator for the difference between this range and another range.
inherited
operator ==(Object that) → bool: Ranges are equal if they have same start and end dates and inclusions.
