usage example

package main

import "abc/P99"
import "fmt"

type aaa struct {
	id int
}

func (a *aaa) Init() int {
    return 1
}

func (a *aaa) Run() int {
	fmt.Println("aaa id: ", a.id)
    return 1
}

type bbb struct {
	id int
}

func (b *bbb) Init() int {
    return 1
}

func (b *bbb) Run() int {
	fmt.Println("bbb id: ", b.id)
    return 1
}

func main() {
    f1 := P99.NewP99Stat(8, 4)

    var a1 aaa
    a1.id = 1
    f1.P99Register(a1.Init, a1.Run)

    var a2 aaa
    a2.id = 2
    f1.P99Register(a2.Init, a2.Run)

    var b1 bbb
    b1.id = 3
    f1.P99Register(b1.Init, b1.Run)

    var b2 bbb
    b2.id = 4
    f1.P99Register(b2.Init, b2.Run)

    fmt.Println("数量: ", f1.P99IfCount())

    f1.P99Run()
}

example output

数量:  4
bbb id:  4
bbb id:  4
aaa id:  1
aaa id:  1
aaa id:  2
aaa id:  2
bbb id:  3
bbb id:  3
