Implements the Iterator interface.
Public void remove()-This method removes the last elements returned by the iterator.
This is where the Iterator Pattern comes in handy.
If value is present alongside done, it is the iterator's return value.
This sends the iterator i into the anonymous function of which we define as index.
Immutable implementation of the Iterator interface.
Void remove()-Removes from the underlying list the last element returned by the Iterator.
What is the Difference between the Iterator and ListIterator?
The Iterator interface provides a number of methods that are able to iterate over any Collection.
Enumeration is doubly faster than the Iterator and uses very less memory.
To enable programmers to process the elements in a collection one at a time,ES2015 introduced the iterator interface.
Keep calling the next() method on the iterator returned from step 1.
When the iterator's next() method is called,the generator function's body is executed until the first yield expression.
When you dealing with a collection of objects, The Iterator Pattern is the ideal solution.
The Iterator Pattern gives you a way of accessing the elements inside an object without having to know the internal details of that object.
Iterating over an iterator is said to consume the iterator, because it is generally only possible to do once.
However, the Iterator is much safer compared to Enumeration, because other threads are not able to modify the collection object that is currently traversed by the iterator.
RxJS is a combination of the best ideas from the Observer pattern, the Iterator pattern, and functional programming.
Storing an integer n in the iterator queue causes the next command to be executed n times.
ReactiveX is a framework encapsulating the best of the Observer pattern, the Iterator pattern and functional programming.
ListIterator is inherited from the Iterator interface but it comes with some extra functionalities, like adding or replacing an element, getting the index position of the previous and next element.
ReactiveX is a combination of the best ideas from the Observer pattern, the Iterator pattern, and functional programming.
More specifically an iterator is any object which implements the Iterator protocol by having a next() method which returns an object with two properties: value, the next value in the sequence;
If an exception StopIteration is raised from within next(),it means there are no more values in the iterator and the loop is exited.
An Iterable is a lazily consumed sequence-each item is pulled by the iterator whenever it wants to use it, and hence the enumeration is driven by the consumer.
The better way is to employ an iterator,which is an object that implements either the Iterator or the ListIterator interface.
Note that a for loop doesn't know what kind of object it's dealing with-it just follows the iterator protocol, and is happy to get item after item as it calls next().
The easiest way to do this is to employ an iterator,an object that implements either the Iterator or the Listiterator interface.
So the generator object is sort of like an adapter-at one end it exhibits the iterator protocol, by exposing__iter__() and next() methods to keep the for loop happy.
