use of com.massivecraft.massivecore.item.DataBannerPattern in project MassiveCore by MassiveCraft.

the class AdapterBannerPatterns method deserialize.

// -------------------------------------------- //
// OVERRIDE
// -------------------------------------------- //
// Default serialization is fine.
// We do however provide a smarter deserialiser.
// This is for the sole purpose of upgrading from the old deprecated database format.
// 
// In the old version (around version 2.8.10) we made use of a list with primitives.
// id, color, id, color...
// They were just coming in that order and were not wrapped in some kind of entry.
// 
// The data types are the same in the old and new version.
// String, Number, String, Number...
// 
// In the new version we do however wrap them in the DataBannerPattern.
