Go 我能得到一些关于“并发素数筛”示例的说明吗?
我是新手,有人能帮我解释一下这个例子吗:Go 我能得到一些关于“并发素数筛”示例的说明吗?,go,goroutine,Go,Goroutine,我是新手,有人能帮我解释一下这个例子吗: // A concurrent prime sieve package main // Send the sequence 2, 3, 4, ... to channel 'ch'. func Generate(ch chan<- int) { for i := 2; ; i++ { ch <- i // Send 'i' to channel 'ch'. } } // Copy the values f
// A concurrent prime sieve
package main
// Send the sequence 2, 3, 4, ... to channel 'ch'.
func Generate(ch chan<- int) {
for i := 2; ; i++ {
ch <- i // Send 'i' to channel 'ch'.
}
}
// Copy the values from channel 'in' to channel 'out',
// removing those divisible by 'prime'.
func Filter(in <-chan int, out chan<- int, prime int) {
for {
i := <-in // Receive value from 'in'.
println("debug", i, prime)
if i%prime != 0 {
out <- i // Send 'i' to 'out'.
}
}
}
// The prime sieve: Daisy-chain Filter processes.
func main() {
ch := make(chan int) // Create a new channel.
go Generate(ch) // Launch Generate goroutine.
for i := 0; i < 10; i++ {
prime := <-ch
print(prime, "\n")
ch1 := make(chan int)
go Filter(ch, ch1, prime)
ch = ch1
}
}
- 以一种简单的方式,假设每个通道都是一组数字(第一个通道由
func提供,包含所有整数)和一个前导数字(我们通过generate
prime:=获得它),我也有同样的问题,在弄明白后写了出来。希望能有所帮助
