Primitive Method

"When it comes to subclassing, knowing which methods are ‘primitive’ methods is important.

The notion of primitive methods are those methods form the basis of the public interface/class.

The rest of the methods are just convenience methods built around them. When overriding a

class behavior with subclassing, just overriding those primitive are often enough." Ref[1]

ObjC.class-cluster

class cluster In a class cluster, only an abstract superclass is public. Allocating an instance actually creates an object of a private subclass. As such, subclassing always happens on an abstract class and requires all methods to be implemented. See

How to implement equals() and hashCode() methods in Java[reproduced]

Part I:equals() (javadoc) must define an equivalence relation (it must be reflexive, symmetric, and transitive). In addition, it must be consistent (if the objects are not modified, then it must keep returning the same value). Furthermore, o.equals(n

深入解析 ObjC 中方法的结构

因为 ObjC 的 runtime 只能在 Mac OS 下才能编译,所以文章中的代码都是在 Mac OS,也就是 x86_64 架构下运行的,对于在 arm64 中运行的代码会特别说明. 在上一篇分析 isa 的文章从 NSObject 的初始化了解 isa中曾经说到过实例方法被调用时,会通过其持有 isa 指针寻找对应的类,然后在其中的 class_data_bits_t 中查找对应的方法,在这一篇文章中会介绍方法在 ObjC 中是如何存储方法的. 这篇文章的首先会根据 ObjC 源代码来分
