示例1: moveTagsTo
// moveTagsTo() gets the tags for all of the src's subiterators and the
// src itself, and moves them to dst.
func moveTagsTo(dst graph.Iterator, src *And) {
tags := src.getSubTags()
for _, tag := range dst.Tagger().Tags() {
if _, ok := tags[tag]; ok {
delete(tags, tag)
}
}
dt := dst.Tagger()
for k := range tags {
dt.Add(k)
}
