no setter, override

hashCode → int

The hash code for this object.

no setter, inherited

isEmpty → bool

Whether this collection has no elements.

Methods

add(ZFrame value) → void

Adds value at the end of the queue.

override

addAll(Iterable<ZFrame> iterable) → void

Adds all elements of iterable at the end of the queue. The length of the queue is extended by the length of iterable.

override

addFirst(ZFrame value) → void

Adds value at the beginning of the queue.

override

addLast(ZFrame value) → void

Adds value at the end of the queue.

override

any(bool test(ZFrame element)) → bool

Checks whether any element of this iterable satisfies test.

override

cast<R>() → Queue<R>

Provides a view of this queue as a queue of R instances, if necessary.

override

clear() → void

Removes all elements in the queue. The size of the queue becomes zero.

override

contains(Object? element) → bool

Whether the collection contains an element equal to element.

override

elementAt(int index) → ZFrame

Returns the indexth element.

override

every(bool test(ZFrame element)) → bool

Checks whether every element of this iterable satisfies test.

override

expand<T>(Iterable<T> toElements(ZFrame element)) → Iterable<T>

Expands each element of this Iterable into zero or more elements.

override

firstWhere(bool test(ZFrame element), {ZFrame orElse()?}) → ZFrame

The first element that satisfies the given predicate test.

override

fold<T>(T initialValue, T combine(T previousValue, ZFrame element)) → T

Reduces a collection to a single value by iteratively combining each element of the collection with an existing value

override

followedBy(Iterable<ZFrame> other) → Iterable<ZFrame>

Creates the lazy concatenation of this iterable and other.

override

forEach(void action(ZFrame element)) → void

Invokes action on each element of this iterable in iteration order.

override

join([String separator = '']) → String

Converts each element to a String and concatenates the strings.

override

lastWhere(bool test(ZFrame element), {ZFrame orElse()?}) → ZFrame

The last element that satisfies the given predicate test.

override

map<T>(T toElement(ZFrame e)) → Iterable<T>

The current elements of this iterable modified by toElement.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

reduce(ZFrame combine(ZFrame value, ZFrame element)) → ZFrame

Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.

override

remove(Object? value) → bool

Removes a single instance of value from the queue.

override

removeFirst() → ZFrame

Removes and returns the first element of this queue.

override

removeLast() → ZFrame

Removes and returns the last element of the queue.

override

removeWhere(bool test(ZFrame element)) → void

Removes all elements matched by test from the queue.

override

retainWhere(bool test(ZFrame element)) → void

Removes all elements not matched by test from the queue.

override

singleWhere(bool test(ZFrame element), {ZFrame orElse()?}) → ZFrame

The single element that satisfies test.

override

skip(int count) → Iterable<ZFrame>

Creates an Iterable that provides all but the first count elements.

override

skipWhile(bool test(ZFrame value)) → Iterable<ZFrame>

Creates an Iterable that skips leading elements while test is satisfied.

override

take(int count) → Iterable<ZFrame>

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

override

takeWhile(bool test(ZFrame value)) → Iterable<ZFrame>

Creates a lazy iterable of the leading elements satisfying test.

override

toList({bool growable = true}) → List<ZFrame>

Creates a List containing the elements of this Iterable.

override

toSet() → Set<ZFrame>

Creates a Set containing the same elements as this iterable.

override

toString() → String

A string representation of this object.

override

where(bool test(ZFrame element)) → Iterable<ZFrame>

Creates a new lazy Iterable with all elements that satisfy the predicate test.

override

whereType<T>() → Iterable<T>

Creates a new lazy Iterable with all elements that have type T.

override

Operators

operator ==(Object other) → bool

The equality operator.
