STL Source code Analysis-iterator and traits programming methodThe central idea of STL is to separate the algorithms from the containers, design them independently, and finally glue them together, and the generics of the algorithms and containers are not very difficult, C + + class templates and function templates can achieve the goal, but sticking together is the thing of the iterator.So the iterator is to glue the algorithm and the container, if the

Trait trait is a unique feature of Scala, unlike C # and Java, if you must compare C # with a particular feature in Java, the closest thing should be an interface, but C # and Java interfaces are not allowed to be implemented with methods, The trait in Scala can be implemented with a method. Defining traits: The predefined classes are the same, but the keyword has changed. Trait xx{ Def method () {...} } Usage characteristics: Class F extends XX {} Th

-- This article was written directly according to teacher Hou Jie and has almost no self-processed content. It is a summary of learning. Traits Programming Techniques In order, this time it should be the content of the iterator. However, an important technique involved in iterator is the traits programming technique. It is worth introducing in a separate chapter. IGet the corresponding type of iterator (as

This article introduces Traits in PHP. Traits is a code reuse mechanism designed for a single inheritance language similar to PHP. if you need it, refer to PHP as a single inheritance language, before the emergence of PHP 5.4 Traits, PHP classes cannot inherit attributes or methods from both base classes. Php's Traits

Original link: http://tabalt.net/blog/php-traits/ PHP is a single-inheritance language, and PHP's class cannot inherit properties or methods from two base classes at the same time before PHP 5.4 traits appears. PHP's traits is similar to the Go language, which declares the trait name to be combined by using the USE keyword in a class, whereas a trait declaratio

This article mainly introduces the example of code reuse using traits in PHP, this article explains the simple use of Trait, priority issues, multiple Trait conflicts, as can be used to modify methods for access control, and Trait This article mainly introduces the example of code reuse using traits in PHP, this article explains the simple use of Trait, priority issues, multiple Trait conflicts, as can be u

The traits technology is widely used in STL, through which you can easily extract the features of an object. It is also used in STL to optimize the performance. For example, if an object is a POD object (Plain Old Data), it can be directly copied through functions such as memcpy during the copy process, instead of calling the copy constructor or operator =. Let's take a look at iterator, the most basic object in STL.The code above shows that the value

This article mainly introduces the example of code reuse using traits in PHP, this article describes the simple use of Trait, priority issues, multiple Trait conflicts, as can be used to modify method access control, and Trait usage in Trait, you can refer to PHP 5.4 and add traits to implement code reuse. Trait is similar to the class, but it cannot be instantiated. you do not need to inherit it. you only

---restore content starts---PHP 5.4.0 started, PHP implemented a code reuse method, called traits.Traits is a similar multi-inheritance method in PHP. Trait to reduce the limitations of single-inheritance languages, developers are free to reuse the set of methods in separate classes within different hierarchies. The semantics of Traits and class combinations are defined as a way to reduce complexity and to avoid the typical problem of traditional mult

Questions and Requirements:Please read this article first, theexperience of utilizing C + + template (traits) in the "C + + Templates Tour" project. For the questions raised in this article, I give a new idea.

PHP5.4 after the new traits implementation of code reuse mechanism, trait and class similar, but can not be instantiated, do not need to inherit, only in the class using the keyword use to introduce can be introduced into a number of traits, with ', ' separated. (1) Trait simple use (2) Priority issuesTrait overrides the inherited method, and the current class overrides the trait method.
