Code sample

Go


// City represents a city.
type City struct {
	Name       string   `firestore:"name,omitempty"`
	State      string   `firestore:"state,omitempty"`
	Country    string   `firestore:"country,omitempty"`
	Capital    bool     `firestore:"capital,omitempty"`
	Population int64    `firestore:"population,omitempty"`
	Regions    []string `firestore:"regions,omitempty"`
}

Java

public City() {
  // Must have a public no-argument constructor
}

// Initialize all fields of a city
public City(
    String name,
    String state,
    String country,
    Boolean capital,
    Long population,
    List<String> regions) {
  this.name = name;
  this.state = state;
  this.country = country;
  this.capital = capital;
  this.population = population;
  this.regions = regions;
}

Python

class City(object):
    def __init__(self, name, state, country, capital=False, population=0,
                 regions=[]):
        self.name = name
        self.state = state
        self.country = country
        self.capital = capital
        self.population = population
        self.regions = regions

    @staticmethod
    def from_dict(source):
        # ...

    def to_dict(self):
        # ...

    def __repr__(self):
        return(
            f'City(\
                name={self.name}, \
                country={self.country}, \
                population={self.population}, \
                capital={self.capital}, \
                regions={self.regions}\
            )'
