custom iterator

vector Container Vectors are a collection of objects of the same type, each with a corresponding integer index value. As with string objects, the standard library is responsible for managing the associated memory of the storage element. We refer to

In. net, the iterator mode is encapsulated by ienumerator, ienumerable, and their corresponding generic interfaces. If a class implements the ienumerable interface, it can be iterated. Calling the getenumerator method will return the implementation

This article mainly introduces the iterator and generator in Python, which involves many important features in Python. For more information, see in Python, many objects can be directly traversed through the for statement, such as list, string, dict,

Both the iterator and generator are unique concepts in Python. The iterator can be considered as a special object. Each time you call this object, it will return its next element. In terms of implementation, an iteratable object must be an object

Checked iterator is an iterator with the out-of-boundary check function, and will trigger error processing during runtime when an out-of-boundary check is performed (call an invalid parameter processing routine or throw an exception ). Vc has

C # iterator [transfer], The iterator pattern is an example of the behavioral pattern in the design pattern. It is a mode that simplifies communication between objects and is also a mode that is easy to understand and use. In simple terms, the

I. OverviewProvides a way to access the aggregation object (container container) without exposing the object's internal details.Second, the application scenario1> iterates through the elements in the aggregation object without exposing its content

Python iteration and iterator, and python We will learn important concepts of python iterations and iterators through simple and practical examples such as list iterator and xrange. Iteratable A sequence of objects, physical or virtual storage. List,
