示例1: addCallees
// addCallees adds client data and links for the facts that site calls fns.
func (a *analysis) addCallees(site ssa.CallInstruction, fns []*ssa.Function) {
v := calleesJSON{
Descr: site.Common().Description(),

}
var this *types.Package // for relativizing names
if p := site.Parent().Package(); p != nil {

}
for _, fn := range fns {
v.Callees = append(v.Callees, anchorJSON{
Text: prettyFunc(this, fn),

start: offset,
end: offset + len("("),
title: fmt.Sprintf("%d callees", len(v.Callees)),
onclick: fmt.Sprintf("onClickCallees(%d)", fi.addData(v)),
})
