In our process App When developing , A common operation is to determine whether two objects are equal . For example, whether two strings are equal . The so-called equal It has two meanings . One is that the values are equal , There is also a reference to equality . If you are familiar with Objective-C To develop it , You know that Objective-C Provides us with a series of isEqual: Method to determine whether the values are equal , and == The equal sign is used to determine whether references are equal . Let's take a look at one Objective-C You'll see more clearly from the example of :

NSArray *arr1 = @[@"cat",@"hat",@"app"];
NSArray *arr2 = @[@"cat",@"hat",@"app"]; NSLog(@"result %i", (arr1 == arr2)); // result 0
NSLog(@"result %i", [arr1 isEqualToArray:arr2]); // result 1

In the above code , We define two arrays ,arr1 and arr2 These two arrays hold the same elements . Next we compare them equally and output the result . For the first time, we used == Compare with the equal sign , The result is 0, That is to say, the comparison failed . I believe that students with some experience should understand , Because stay Objective-C in == The comparison is to quote , because arr1 and arr2 It's two different objects , So even if their values are the same , But their citations are also different . therefore == Comparison will fail . And the second comparison is NSArray Of isEqualToArray Method , This method is used for value comparison , Because the values of the two arrays are the same , therefore isEqualToArray The comparison method returns 1.

Equatable agreement

We go through Objective-C I understand equal The operation mechanism of operation , Contains value equality and reference equality . Now let's go back to Swift In the to . Believe there is Objective-C Experienced students will be looking for isEqual Method , But you will find Swift None of the native classes of isEqual The definition of .

If you want to isEqual Get to know more about , This article Equality It has a detailed explanation . Let's just talk about it here .

Swift There is no iEqual Method definition , But in a more natural way , Overload operators To deal with it equal Judgmental . heavy load == The operator is through Equatable Agreement to complete . We implement the methods in this protocol to overload operators .

func ==(lhs: Self, rhs: Self) -> Bool

Swift Implementation of the array class , be called Array, About Array type , This article has a detailed description Swift Tips - Array type .Swift Medium Array Type implements Equatable agreement , So we can Array Examples of types are provided through == Operators for comparison :

var arr1 = ["cat","hat","app"]
var arr2 = ["cat","hat","app"]
println arr1 == arr2 // true

We see , stay Swift You can use == Compare the effect and Objective-C Medium isEqual: The actual effect of the method is the same . They all compare values .Swift This point of characteristic and Objective-C It's a little different .Swift In the native class of , It's almost done Equatable agreement .

Realization Equatable agreement

We now understand Swift Medium Equatable agreement . I believe careful students have found out , We are Swift The reason why we can use == Compare , Because the object of this symbolic operation implements Equatable agreement . If you use it for objects that don't implement this protocol == For comparison ? We can take a look at this code :

In the above code , We define a Name class , And instantiate two objects of this class john and copy. And then we use == Compare the two , At this point, the compiler reported an error . The reason is that our class doesn't implement Equatable agreement .

Now let's modify this class :

class Name :Equatable {
var firstName:String?
var lastName:String? init(firstName first:String, lastName last:String){ self.firstName = first
self.lastName = last } }
func ==(lhs: Name, rhs: Name) -> Bool { return lhs.firstName == rhs.firstName && lhs.lastName == rhs.lastName }

In our revision , We did Equatable agreement , And implemented func ==(lhs: Name, rhs: Name) -> Bool Method . The only way to judge is firstName and lastName If they are all equal , these two items. Name Objects are equal .

After making this change , We can continue to use our previous judgment :

if john == copy {
print("equal") //equal
}

This time, ,if Statement print The method was successfully implemented .

Now we know Swift Most classes in have their own pairs of == The implementation of the operator . So what if we want to compare whether the references of two objects are equal ?

We can use ObjectIdentifier Class to get the reference ID of the object , We explicitly call the constructor of this class to get the object reference , And compare :

if ObjectIdentifier(john) == ObjectIdentifier(copy) {
print("equal")
}else{
print("not equal") // not equal
}

We use it ObjectIdentifier Got the reference address of the object , also ObjectIdentifier It's realized itself Equatable agreement , therefore We're interested in the converted ObjectIdentifier Object use == Compare , You can tell if the application is the same .

Comparable

We just introduced Equatable agreement , And there's another one related to it Comparable agreement . Equatable The protocol is to compare equality . and Comparable It's a comparison of the order . such as Swift Medium Double class , And that's what happened Comparable agreement :

var left:Double = 30.23
var right:Double = 50.55 if left < right { print("30.23 is less than 50.55") }

Realized Comparable Protocol class , You can use >,<,<=,>= These operators compare . The definition of this agreement is as follows :

protocol Comparable { ... }
func <=(lhs: Self, rhs: Self) -> Bool
func >=(lhs: Self, rhs: Self) -> Bool
func >(lhs: Self, rhs: Self) -> Bool

Do you think , To implement the comparison operation , We need to realize all the methods in this . Let's take a few minutes to take a closer look at the definition of this Agreement , And think about it .

  1. First , There are four operators for order comparison ,<=,>=,>,< You can take a look at this agreement , It seems that it's missing < What about the definition of ?
  2. then , Let's analyze the logic of these operators ,>=, It's actually > and == A juxtaposition of , If we implement these two operators , actually >= The logic of this is clear . This >= The logic of the operator is usually this statement : return lhs > rhs || lhs == rhs.

Through the above brief analysis , Did we find a rule ? In fact, that is , We just need to implement some operators , You can deduce the logic of other operators . for instance , On the surface of the above Comparable From the definition of interface ,<= and > These two operators , We only need to implement one of them to derive the other . such as , We did > The operator , that '<=' The operator only needs to negate the previous function .

that , We <= Implementation of function , Just do something like this :

func <=(lhs: Self, rhs: Self) -> Bool {
return !(lhs > rhs)
}

Think about it , In fact, we just need to achieve == and < The operator , Several other operators can be derived from these two :

  1. >= Can pass < The logic of negation and == A logic or operation derived together .
  2. > Can pass < We can deduce from the logic of .
  3. <= Can pass < and == The logic or operation of .

About this knowledge , There is a concept called Strictly total order , Students who are interested can read .

Now the problem is again , We just need to achieve == and < Method logic can complete the comparison operation , So the implementation code for other operators , It's all the same . It's redundant .

and Swift It's solving this problem for us , Provides us with the default implementation of the protocol , go through Swift Document , We'll find that in addition to Comparable agreement , I've also defined one _Comparable agreement , The former is inherited from the latter . _Comparable The definition of the agreement is as follows :

protocol _Comparable { ... }
func <(lhs: Self, rhs: Self) -> Bool

We found that , What we just lost < I found... Here . _Comparable Namely Swift An example of the default protocol implementation mechanism provided in ._Comparable Several other operators are provided in the protocol >=,>,<= Default implementation of .

because Comparable Simultaneous inheritance from _Comparable and Equatable agreement , So we just need to achieve < and == These two operators , Can complete the implementation of the whole comparison operation . Let's take an example :

class Name: Comparable {
var firstName:String
var lastName:String init(firstName first:String,lastName last:String){ self.firstName = first
self.lastName = last }
} func ==(lhs: Name, rhs: Name) -> Bool { return lhs.firstName == rhs.firstName && lhs.lastName == rhs.lastName
} func <(lhs: Name, rhs: Name) -> Bool { return lhs.firstName < rhs.firstName && lhs.lastName < rhs.lastName } let john = Name(firstName: "John", lastName: "Smith")
let johnClone = Name(firstName: "John", lastName: "Smith")
let jack = Name(firstName: "Jack", lastName: "Smith")
let mary = Name(firstName: "Mary", lastName: "Williams") print(john >= jack) //true
print(john <= jack) //true
print(john == jack) //false
print(john > jack) //false
print(john < jack) //false
print(jack < mary) //true
print(john == johnClone) //true var names:Array<Name> = [johnClone,mary,john,jack]
//[{firstName "John" lastName "Smith"}, {firstName "Mary" lastName "Williams"}, {firstName "John" lastName "Smith"}, {firstName "Jack" lastName "Smith"}]
names.sort { (lhs, rhs) -> Bool in
return lhs > rhs
} //[{firstName "Mary" lastName "Williams"}, {firstName "John" lastName "Smith"}, {firstName "John" lastName "Smith"}, {firstName "Jack" lastName "Smith"}]

We're here to complete Comparable agreement , We define a Name class , And implemented < and == Protocol method , One of them is from _Comparable agreement , One from Equatable agreement . and Comparable Three comparison methods in the protocol , Already in _Comparable The default implementation is provided in , So we don't have to do it ourselves again .( Pay attention to two Comparable and _Comparable The difference between underscores , These are two different agreements .)

Hashable

The last thing to mention is Hashable agreement . We are right. Dictionary It should be no stranger to the concept of , So if an object wants to be Dictionary Of key Words , Then we need to achieve Hashable agreement .

Swift The following classes are implemented by default Hashable agreement :

  • Double
  • Float, Float80
  • Int, Int8, Int16, Int32, Int64
  • UInt, UInt8, UInt16, UInt32, UInt64
  • String
  • UnicodeScalar
  • ObjectIdentifier

So instances of these classes , It can be used as Dictionary Of key. Let's take a look Hashable Definition of agreement :

protocol Hashable { ... }
var hashValue: Int { get }

The definition is very simple , We just need to achieve hashValue Definition hash The calculation method of the value is just . About hash The optimization method of value is another topic , So we'll just have a brief discussion here , Will use the hash Value again XOR operation to calculate the new hash value . Or our Name Class, for example :


class Name: Comparable,Hashable { ... var hashValue: Int {
return self.firstName.hashValue ^ self.lastName.hashValue
} }

Next we'll use it as a dictionary key 了 :

let john = Name(firstName: "John", lastName: "Smith")
let johnClone = Name(firstName: "John", lastName: "Smith")
let jack = Name(firstName: "Jack", lastName: "Smith")
let mary = Name(firstName: "Mary", lastName: "Williams") var nameMap:[Name: String] = [:]
nameMap[john] = "Manager"
nameMap[jack] = "Stuff"

This article introduces Swift Three agreements in Equatable,Comparable,Hashable, Although we usually don't pay much attention to these agreements , But in our development work , They don't work all the time , our if sentence , The sorting operation , Dictionary and array operations , It's all about these agreements . and Swift Most of the categories in , Basically, these agreements have been realized . It can be said that although we often forget them , But they are around us all the time . After getting to know them , It will help us a lot .
