All Implemented Interfaces:

Cache<K,V>

public final class JITOptimizedCache<K,V>
extends OptimizedCacheBase<K,V>

JIT-optimized cache implementation focused on hot path performance. Key optimizations: - Method inlining hints via small methods - Monomorphic call sites - Branch prediction optimization - Minimal object allocation in hot paths - Cache-friendly data structures
