bag

Small demo of the common functions in the bag package.

package main

import (
	"fmt"

	"gopkg.in/karalabe/cookiejar.v2/collections/bag"
)

func main() {
	// Create a new bag with some integers in it
	b := bag.New()
	for i := 0; i < 10; i++ {
		b.Insert(i)
	}
	b.Insert(8)
	// Remove every odd integer
	for i := 1; i < 10; i += 2 {
		b.Remove(i)
	}
	// Print the element count of all numbers
	for i := 0; i < 10; i++ {
		fmt.Printf("#%d: %d\n", i, b.Count(i))
	}
	// Calculate the sum with a Do iteration
	sum := 0
	b.Do(func(val interface{}) {
		sum += val.(int)
	})
	fmt.Println("Sum:", sum)
}

Output:

#0: 1
#1: 0
#2: 1
#3: 0
#4: 1
#5: 0
#6: 1
#7: 0
#8: 2
#9: 0
Sum: 28
