假设我有一个Graph
结构,如下所示:
type Graph struct {
nodes []int
adjList map[int][]int
}
// some methods on the struct
// constructor
func New() *Graph {
g := new(Graph)
g.adjList = make(map[int][]int)
return g
}
现在,我使用:aGraph := New()
创建该结构的新实例。
如何访问Graph
结构(aGraph
)的此特定实例的字段?
换句话说,如何访问aGraph
版本的nodes
数组(例如,来自另一个顶级函数)?
非常感谢任何帮助!

以下是一个例子:
package main
import (
"fmt"
)
// example struct
type Graph struct {
nodes []int
adjList map[int][]int
}
func New() *Graph {
g := new(Graph)
g.adjList = make(map[int][]int)
return g
}
func main() {
aGraph := New()
aGraph.nodes = []int {1,2,3}
aGraph.adjList[0] = []int{1990,1991,1992}
aGraph.adjList[1] = []int{1890,1891,1892}
aGraph.adjList[2] = []int{1890,1891,1892}
fmt.Println(aGraph)
}
输出:& {[1 2 3 4 5] map [0:[1990 1991 1992] 1:[1890 1891 1892] 2:[1790 1791 1792]]}
