CoreLib is a library mod for data handling.<\/p>\n

## Features<\/p>\n

### Extra codecs<\/p>\n

CoreLib comes with new codecs for classes including, but not limited to:<\/p>\n

– BigInteger
\n– BigDecimal
\n– GameProfile
\n– OptionalLong
\n– RegistryKey
\n– TagKey<\/p>\n

### Automatic codec generation<\/p>\n

CoreLib can **automatically resolve codecs** for given classes, **including generic classes** with **type parameters**.
\nIt can also **dynamically** create **new codecs** for any **enum**, as well almost **any record**.<\/p>\n

CoreLib can resolve a codec for **a record** as long as it can also resolve a codec for _all_ the record’s components.<\/p>\n

### Automatic data saving \/ loading<\/p>\n

CoreLib also features a `SaveData` class, which handles **saving and loading** data to and from the disk. Certain classes that extend from this class **automatically** save and load your data. One is meant for data attached to **an instance** (modpack), while the other is meant for data attached to **each world** (save file).<\/p>\n

### Automatic data synchronisation<\/p>\n

CoreLib includes a `SyncedData` class, for **automatically synchronising data** to client through a utility class called `Synchronisation`.
\nCoreLib includes `SaveData` classes that **implement this interface** and are automatically synced to _all_ clients.<\/p>\n","protected":false},"excerpt":{"rendered":"
