Suggestion for Storing HashMap in NBT

I was wondering if someone has done this before that they would be able to let me know how. I want to take a Lua table (HashMap) and store it in the NBT of the peripheral's TileEntity.

I haven't done modding in a while, but if I recall correctly, you would do something like this (pseudocode):

// Our map in NBT form
NBTTagCompound nbtMap = new NBTTagCompound();

// Copy every element from the HashMap to the NBTTagCompound
for (every key value pair in the map) {
   nbtMap.setString(key, value); // This might not be setString in your case!
}

// Save it in the TileEntity's compound
tileEntityNBT.setTag("MyMap", nbtMap);

Of course, you can only store types in the map that are supported by NBT. Since your map represents a Lua table, this shouldn't be a problem.

Thanks!
