Could you please provide a bit more context, like what version you are talking about, what was the usage of the method and what was the return type?

Returns a NBTTagCompound that can be used to store custom data for this entity. It will be written, and read from disc, so it persists over world saves.
Returns:
A NBTTagCompound

Probably you mean Entity#getPersistentData, if you want to store data in this CompoundTag,
create a second CompoundTag store there all data you want to store then put this CompoundTag with your mod id as key into the PersistentData of the Entity.

But i would highly recommend you to use a Capability, see: https://forge.gemwire.uk/wiki/Capabilities.
