Class MapContainer<S extends Tracked<K>,K extends WorldKey>

java.lang.Object
net.paulem.arcana.regions.container.blocks.MapContainer<S,K>
Type Parameters:
S - the type of tracked objects, which must implement the Tracked interface
K - the type of the key associated with the tracked object
All Implemented Interfaces:
SectionContainer<S,K>
public class MapContainer<S extends Tracked<K>,K extends WorldKey> extends Object implements SectionContainer<S,K>
A SectionContainer implementation backed by a sparse Int2ObjectOpenHashMap. Well-suited for sections with few occupied positions, since it only allocates entries for positions that are actually in use.
