Introduction Lambda expressions are an important feature introduced in Java 8 that allow us to write anonymous functions in a more concise way. Before discussing Lambda expressions, let us first review the problems with anonymous inner classes. Problems with anonymous inner classes Before Java 8, we usually used anonymous inner classes to pass behavior. For […]

Comparator interface and Lambda expression
Introduction After you have learned Lambda expressions and Java function references, you can learn more about the Comparator interface. It provides many useful methods and many functional interface parameters for you to use. The essential purpose is to allow you to It is possible to write a sorting method as simply as possible. Note: The […]
C/C++ 11/14 rewrites a std::function<…> function template that supports safety and no multiple copies, supports Lambda λ and overloaded operator()(…) operator structure and C/C++ language Ordinary functions.
As the title of this article indicates, it was rewritten for optimization, and the solid-size BUFF buffer provided by the standard library std::function implementation was cut off because it is no longer necessary. The implementation copies the shared pointer. Reference, instead of needing to copy the BUFF and reconstruct it like the official version. If […]

Lambda expressions in C++11
Lambda comes from the concept of functional programming. C++11 finally adds lambda this time. Lambda expressions have the following advantages: 1. Declarative programming style: define the target function or function object anonymously in place, without writing an additional named function or function object. Write programs in a more direct way, with good readability and maintainability. […]

Lambda expression 1.Lambda expression usage scenarios: Lambda expressions can replace anonymous inner classes in most situations. Note that, as mentioned above, the application of Lambda is to cancel anonymous inner classes in most situations. (It can only replace the creation of anonymous inner classes for interfaces with only one abstract method, because the program needs […]
