这里的having到底何意

If my friend would undertake it there is no man who is better worth having at your side when you are in a tight place.

No one can say so more confidently than I.

不可以理解上句worth having中的having是什么含义？麻烦老师解析一下这里的having是什么含义，等于什么动词？



have sb at your side. 字面意思：有某人在你身边。引申意思：有某人支持你，得到了某人的支持。

sb is worth having at your side : 有某人支持你是值得的。be worth+doing, 动名词为悬空结构，主语为doing的逻辑宾语。
