You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: pathaction.go
    path of file: ./repos/kubeedge/vendor/github.com/exponent-io/jsonpath
    
    the code of the file until where you have to start completion: package jsonpath

// pathNode is used to construct a trie of paths to be matched
type pathNode struct {
	matchOn    interface{} // string, or integer
	childNodes []pathNode
	action     DecodeAction
}

// match climbs the trie to find a node that matches the given JSON path.
func (n *pathNode) match(path JsonPath) *pathNode {
	var n
    
func (n *pathNode) match(path JsonPath) *pathNode {
	var node *pathNode = n
	for _, ps := range path {
		found := false
		for i, n := range node.childNodes {
			if n.matchOn == ps {
				node = &node.childNodes[i]
				found = true
				break
			} else if _, ok := ps.(int); ok && n.matchOn == AnyIndex {
				node = &node.childNodes[i]
				found = true
				break
			}
		}
		if !found {
			return nil
		}
	}
	return node
}
