public class MapSync<K, V> extends Object implements MapCollection<K, V>:
Object
└ MapSync
All Implemented Interfaces: MapCollection

Thread-safe balanced binary tree map.

MapSync<K, V> exposes the same typed API as Map<K, V> while the native runtime serializes operations on the instance storage. Keys stay typed as K and values stay typed as V throughout the public API.

Prefer Map<K, V> for single-threaded hot paths. Use this class when shared mutable access from several threads is required.

@param <K> Key type. @param <V> Value type. @since 1.0
