Replacement for the deprecated DataHolder.get(DataKey<T>) method?

[Thilo-Acrolinx]

The com.vladsch.flexmark.util.data.DataHolder.get(DataKey<T>) method has been marked as deprecated (link to source).

The Javadoc comment says "Use key.get(dataHolder) instead", but I fail to understand what that means. I don't see any overloaded "get(dataHolder)" method here, maybe I am overlooking something?

I am looking for a typesafe, not-deprecated API to get the value for a given key from a DataHolder. The getOrCompute() method is no alternative unfortunately, since it returns java.lang.Object and thus is not typesafe but requires ugly casting.

Have searched through all issues and discussions here on GitHub, but without luck, so any help is very much appreciated.
