Adds a PropertyDiff child built from the arguments, updating this diff's type as addChild(Diff) does.

Diff<?>

fromRecord(Record source)

Loads this instance's state from a record and returns this (for fluid API call chaining).

Diff<?>

getChildByName(String name)

Returns the first child with the given name (case-sensitive), or null if there is none.
