Packages

• Packages: JavaPackages

Root object for Java package / class access, e.g. Packages.java.lang.String or Packages.okhttp3.OkHttpClient.

Example

"nodejs";
const { Packages } = require("rhino");

const OkHttpClient = Packages.okhttp3.OkHttpClient;
const client = new OkHttpClient.Builder().build();

console.log(client);

Functions

install

install(scope?: any): void

Install Rhino-style Java interop globals into the given scope. This makes the following identifiers available:

• Packages: Access Java packages and classes.
• java, javax, org, com, edu, net, android: Common Java/Android package roots.
• JavaAdapter: Implement a Java class/interface in JavaScript. Not supported in current versions; calling it will throw.

importClass and importPackage are not supported. Use direct property access instead.

Example

"nodejs";
require("rhino").install();

const View = android.view.View;
const StringBuilder = java.lang.StringBuilder;

console.log(View.class.getName());
console.log(new StringBuilder().append("Hello").toString());

Parameters

• scope: Target scope to install globals into. Defaults to global.

Returns

void
