Package: com.codex.composer.api.v1.data
The classes in this package are various interfaces used for serialization / deserialization.
ComposerCompound only exists in 1.21.4 and earlier, as in 1.21.5+ raw nbt reading and writing was replaced with codecs, and dynamic operations. For the same reason, from 1.21.6 and onwards ComposerReadView and ComposerWriteView are available and offer the same features as ComposerCompound.
This does however mean that there is an intermediate phase of 1.21.5, where neither utility is available; that I cannot do anything about, as in that version NbtCompound was made to be final, so ComposerCompound cannot extend it.
As an example, here's code from both versions that does the same thing:
From Starstruck (Code currently private, sorry)
// 1.21.11@Overridepublic void writeData(@NonNull WriteView view) {ComposerWriteView.begin(view).putList("value", Entry.CODEC, value);}@Overridepublic void readData(@NonNull ReadView view) {value = ComposerReadView.begin(view).getList("value", Entry.CODEC);}// 1.20.1@Overridepublic void writeToNbt(NbtCompound nbt) {nbt.copyFrom(new ComposerCompound().putListFluent("value", value));}@Overridepublic void readFromNbt(NbtCompound nbt) {value = ComposerCompound.copy(nbt).getList("value", Entry::new);}
