Example 1
/**
 * Writes an {@link ItemStack} to the stream.
 * The <code>limitedTag</code> parameter, can be used to force the use of
 * the stack {@link ItemStack#getShareTag()} instead of its {@link ItemStack#getTag()}.
 * Under normal circumstances in Server -> Client sync, not all NBT tags are required,
 * to be sent to the client. For Example, the inventory of a pouch / bag(Containers sync it).
 * However, in Client -> Server sync, the entire tag may be required, modders can choose,
 * if they want a stacks full tag or not. The default is to use {@link ItemStack#getShareTag()}.
 * <p>
 * It should also be noted that this implementation writes the {@link ItemStack#getCount()}
 * as a varInt opposed to a byte, as that is favourable in some cases.
 *
 * @param stack      The {@link ItemStack}.
 * @param limitedTag Weather to use the stacks {@link ItemStack#getShareTag()} instead.
 * @return The same stream.
