[1.7.2]Is it possible to save a World obj. in NBT?

[memcallen]

I have a class which essentially justs saves a block position to nbt and can load it from nbt, and I want to store either a TileEntity or a world obj. in the nbt as well

 

heres my class if you need it:

package com.example.gammacraft.Helpers;

import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.world.World;

public class BlockPos {

int x,y,z;
World world;
TileEntity te;

public BlockPos(int x,int y,int z,World world,TileEntity te) {
	this.x=x;
	this.y=y;
	this.z=z;
	this.world=world;
	this.te=te;
}

public BlockPos(){
}


public void writeToNBT(NBTTagCompound nbt){
	nbt.setInteger("x", x);
	nbt.setInteger("y", y);
	nbt.setInteger("z", z);
}

public void readFromNBT(NBTTagCompound nbt){
	this.x = nbt.getInteger("x");
	this.y = nbt.getInteger("y");
	this.z = nbt.getInteger("z");
}
}
