Invocation context from Perl package in JavaScript app

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

const { Javonet } = require('javonet-nodejs-sdk/lib/sdk/Javonet')

let resourcesDirectory = '.'

// use activate only once in your app
Javonet.activate('your-license-key')

// create called runtime context
let calledRuntime = Javonet.inMemory().perl()

// construct an invocation context - this invocationContext in non-materialized
let invocationContext = calledRuntime.getType('CORE').invokeStaticMethod("length", "sample text")

// execute invocation context - this will materialize the invocationContext
let response = invocationContext.execute()
// use activate only once in your app
Javonet.activate('your-license-key')

// create called runtime context
let calledRuntime = Javonet.inMemory().perl()

// construct an invocation context - this invocationContext in non-materialized
let invocationContext = calledRuntime.getType('CORE').invokeStaticMethod("length", "sample text")

// execute invocation context - this will materialize the invocationContext
let 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
