Class

Flow-Wing supports classes and objects.

Classes

In Flow-Wing, classes are defined using the class keyword.

Example:

class Person {
 var name: str
 var age: int

 init(name: str, age: int) -> nthg {
     self.name = name
     self.age = age
 }

 print() -> nthg {
     print(self.name, " is ", self.age, " years old.")
 }

 getAge() -> int {
     return self.age
 }

 setAge(age: int) -> nthg {
     self.age = age
 }

}

const person: Person = Person("Alice", 30)

person.print()
print("\n"person.getAge())

Output:

Alice is 30 years old.
30

Here, Person is a class that has two properties name and age, and two methods print and getAge. init is a constructor that initializes the properties of the class. setAge is a method that sets the value of the age property.

Multiple Constructors Example

Flow-Wing supports multiple constructors. The init keyword can have multiple constructors.

class Person {
 var name: str
 var age: int

 init(name: str, age: int) -> nthg {
     self.name = name
     self.age = age
 }
}
