Class EventHandler

java.lang.Object
com.hypixel.hytale.builtin.worldgen.modifier.EventHandler
All Implemented Interfaces:
AutoCloseable
public final class EventHandler extends Object implements AutoCloseable
Coordinates world-generation modifier handling for a specific world-gen content root.

This class gathers applicable WorldGenModifiers, orders them by pack priority and modifier order, groups them by event type, and applies their operations when matching modification events are dispatched. It also manages a thread-local scoped handler so modifier processing can be opened for a loading context and automatically cleared when that scope is closed.
