Method GetNodeFunc

objects.go:46–67

GetNodeFunc is a general-purpose method for finding object properties by their key. The provided function is called with each key in turn. The first time that function returns true the corresponding *Node for that key is returned.

(fn func(key string) bool)

// with each key in turn. The first time that function returns
// true the corresponding *Node for that key is returned.
func (o Object) GetNodeFunc(fn func(key string) bool) *Node {
	if !o.HasValidNode() {
		return &Node{}
	}

	count := int(o.node.NamedChildCount())

	for i := 0; i < count; i++ {
		pair := o.node.NamedChild(i)

		if pair.Type() != "pair" {
			continue
		}

		if !fn(pair.ChildByFieldName("key").RawString()) {
			continue
		}

		return pair.ChildByFieldName("value")
	}
	return nil
