You get the Value<Text>
for the manipulator, then set the contained Text
Something like:
holder.getData(DisplayNameData.class).get().displayName().set(Texts.of("Something"));
Alternatively, you can set the Value
directly
holder.set(Keys.DISPLAY_NAME, Texts.of("Something"));
Note that I have not tested this and it may not compile, but I hope you get the idea.
