Package com.caoccao.javet.interop.engine Description

Engine pool for managing reusable V8/Node.js runtime instances in production.

Creating V8 runtimes is expensive. Use the engine pool to amortize that cost:

• JavetEnginePool - Thread-safe pool of reusable runtimes with automatic lifecycle management.
• JavetEngineConfig - Pool configuration: pool size, runtime type, timeout, auto-reset, etc.
• JavetEngine - A pooled runtime wrapper with usage tracking. Obtain via pool.getEngine() and use with try-with-resources.

Usage:

 try (JavetEnginePool<V8Runtime> pool = new JavetEnginePool<>()) {
     try (IJavetEngine<V8Runtime> engine = pool.getEngine()) {
         V8Runtime runtime = engine.getV8Runtime();
         runtime.getExecutor("1 + 1").executeInteger();
     }
 }
