    • matches

      public static boolean matches(@Nullable @Nullable NbtElement standard, @Nullable @Nullable NbtElement subject, boolean ignoreListOrder)
      Returns whether standard is a subset of subject.

      Elements are matched based on the following order:

      1. Passing the same reference to both parameters will return true.
      2. If standard is null, return true.
      3. If subject is null, return false.
      4. If the types of standard and subject are different, return false.
      5. If standard is NbtCompound, return true if all keys in the standard exist in subject and the values match (comparing recursively.)
      6. If standard is NbtList and ignoreListOrder is true, return true if both lists are empty, or if there exists a "matching" value in subject for all values of standard (that is, if standard is a subset of subject, ignoring duplicates.), otherwise false. This means that the comparison ignores the ordering of the lists.
      7. Otherwise, return standard.equals(subject).
      Parameters:
      standard - the standard (also called as "template" or "schema") element
      subject - the element to test
      ignoreListOrder - whether to ignore ordering for NbtList
      Returns:
      whether standard is a subset of subject

      public static String toNbtProviderString(NbtCompound compound)
      Returns the string representation of compound as used by the NBT provider in the data generator.

      The passed compound will be sorted and modified in-place to make it more human-readable e.g. by converting NbtCompound in the palettes NbtList to its short string representation. Therefore the returned value is not an accurate representation of the original NBT.

      Returns:

      public static NbtCompound fromNbtProviderString(String string) throws com.mojang.brigadier.exceptions.CommandSyntaxException
      Returns the string parsed as an NBT provider-formatted NBT compound.

      This method first parses the string as an NBT, then performs several conversions from human-readable NbtCompound items to the actual values used in-game.
