C++ invocation context from JAR library

Calling any method on Runtime Context creates new instance of Invocation Context.

#include "Javonet.h"
#include <iostream>
#include <vector>

using namespace JavonetNS::Cpp::Sdk;

std::string resourcesDirectory = ".";

int main(int argc, char* argv[]) {

    // use Activate only once in your app
    Javonet::Activate("your-license-key");
    
    // create called runtime context
    auto calledRuntime = Javonet::InMemory()->Jvm();
    
    // construct an invocation context - this invocationContext in non-materialized 
    auto invocationContext = calledRuntime->GetType("java.lang.Math")->InvokeStaticMethod("abs", -50);
    
    // execute invocation context - this will materialize the invocationContext
    auto response = invocationContext->Execute();
}// use Activate only once in your app
Javonet::Activate("your-license-key");

// create called runtime context
auto calledRuntime = Javonet::InMemory()->Jvm();

// construct an invocation context - this invocationContext in non-materialized 
auto invocationContext = calledRuntime->GetType("java.lang.Math")->InvokeStaticMethod("abs", -50);

// execute invocation context - this will materialize the invocationContext
auto response = invocationContext->Execute();

Navigation through the methods on different variations of Invocation Context allows to construct the chain of invocations. Those chains of invocation represent the non-materialized expression of interaction with libraries, types, and any programming entities in target technology.

In order to materialize expression, a call to called technology needs to be invoked with Execute method
