Iterator protocol(adopted from Python).
It looks like a function but acts like an iterator.
Iterator->key() returned value is stored in$key.
In short, a generator looks like a function but behaves like an iterator.
An iterator is behaviorally similar to a database cursor.
Different languages orlibraries used with these languages define iterator types.
Iterator interface allows the iteration of container classes.
Note that I needs not be declared,because declared'var out' in the iterator.
By using an iterator one is isolated from these sorts of consequences.
As an example of real-world usage,the CRTP is used in the Boost iterator library.
Iterator->next() advances to the next element in the internal structure.
All of the standard container template types provide a rich andconsistent set of iterator types.
Java doesn't have iterator blocks for simple implemetation of iterators.
Such an implementation supporting external iteration is demonstrated in MATLAB Central File Exchange item Design Pattern: Iterator(Behavioral).
Iterator->rewind() ensures that the internal structure starts from the beginning.
In Python, a generator is an iterator constructor:a function that returns an iterator.
An iterator may allow the container object to be modified without invalidating the iterator. .
The next() method advances the iterator and returns the value pointed to by the iterator. .
Iterator: This allows us to access the elements of an object sequentially without exposing the underlying structure.
In object-oriented languages an iterator, even if implicit, is often used as the means of traversal.
An iterator is an object that provides iteration as a generic service, allowing iteration to be done in the same way for a range of different data structures.
Instead of the Java“foreach” loops for looping through an iterator, Scala has a much more powerful concept of for-expressions.
Each Iterator provides a next() and hasNext() method, and may optionally support a remove() method.
It is usually characterized by the use of an implicit or explicit iterator, in which the loop variable takes on each of the values in a sequence or other data collection.
When an iterator is advanced beyond the last element it is by definition equal to the special end iterator value.
In addition, associative arrays may also include other operations such as determining the number of bindings or constructing an iterator to loop over all the bindings.
In computer programming, an iterator is an object that enables a programmer to traverse a container, particularly lists.
The iterator returned by begin()points to the first element, while the iterator returned by end() is a special value that does not reference any element.
It is possible to specify more than one iterator variable, in which case they are assigned sequential values from the list.
The iterator object then needs to define a__next__() method that returns the next element and an__iter__() method that returns the next iterator object to use.
