# go sugar

特性:

1. Java Stream -> Go Stream

2. Java 泛型  -> Go T

# Download

```shell

go get github.com/SolarisNeko/go-sugar

```

# Use

## Stream

```go

	stream := Stream{1, 2, 3, 4, 5}

	// 使用 Filter 过滤偶数

	predicate := func(num T) bool {

		if number, ok := num.(int); ok {

			return number%2 == 0

		}

		return false

	}

	// 使用 Map 将每个元素加倍

	mapper := func(n T) T {

		toNumber := generic.ToNumber(n)

		number := generic.ToNumber(2)

		return toNumber * number

	}

	reducer := func(n1 T, n2 T) T {

		return generic.ToNumber(n1) + generic.ToNumber(n2)

	}

	// 输出: 12

	sum := stream.

		Filter(predicate).

		Map(mapper).

		Reduce(0, reducer)

```
