java-concurrent-hash-trie-map

Provides thread-safe, lock-free operations for highly scalable concurrent inserts and removes, as emphasized in the key features for multi-threaded environments.

Enables O(1) atomic snapshots for linearizable size, iterator, and clear operations with lazy evaluation, a unique feature highlighted in the README's description.

Uses a hash array mapped trie to optimize memory usage while maintaining performance, a core advantage noted in the project's key features.

Implements all ConcurrentMap and Iterator methods, passing all tests and matching the original Scala feature set, making it easy to replace ConcurrentHashMap.

Returns Objects instead of Scala's Option types for better Java integration and has no external dependencies, simplifying usage as stated in the README.
