public interface Spawner

Spawns entities in a world.

A spawner is typically used to spawn entities within a special context, such as cats in a village or wandering traders. This is different from the mob spawner logic which is used for the spawner block, or the structure spawn conditions (such as guardians) which is defined in ChunkGenerator.getEntitySpawnList(net.minecraft.registry.entry.RegistryEntry<net.minecraft.world.biome.Biome>, net.minecraft.world.gen.StructureAccessor, net.minecraft.entity.SpawnGroup, net.minecraft.util.math.BlockPos). However, cats in swamp huts are spawned in both CatSpawner and the normal structure spawning.
