Class JavetJVMInterceptor

java.lang.Object

com.caoccao.javet.interception.BaseJavetInterceptor

com.caoccao.javet.interception.BaseJavetDirectCallableInterceptor

com.caoccao.javet.interception.jvm.JavetJVMInterceptor

All Implemented Interfaces:

IJavetInterceptor, IJavetDirectCallable

public class JavetJVMInterceptor
extends BaseJavetDirectCallableInterceptor

The Javet JVM interceptor exposes the whole JVM as javet in V8. It must be accompanied by JavetProxyConverter.

Usages: let sb = new javet.package.java.util.StringBuilder(); sb.append(123).append('abc'); sb.toString(); // 123abc sb = undefined; javet.v8.gc();

Since:

3.0.3
