js-to-java

NPM version build status Test coverage node version npm download

Easy way to wrap js object to java object.

In hessian.js, we need to write java classname with js object so make it encode as the write class.

Install

NPM

$ npm install js-to-java

Usage

Example

var java = require('js-to-java');

// Java: com.java.Object o = new com.java.Object();
java('com.java.Object', { foo: 'bar' });
// => {$class: 'com.java.Object', $: { foo: 'bar' }}

// Java: Boolean r;
java.Boolean(true);
// => {$class: 'java.lang.Boolean', $: true}

// Java: short[] shorts = new short[] {1, 2, 3};
java.array('short', [1, 2, 3]);
// => {$class: '[short', $: [1, 2, 3]}

// Java: int[] ints = new int[] {1, 2, 3};
java.array('int', [1, 2, 3]);
// same to the next example
java.array.int([1, 2, 3]);
// => {$class: '[int', $: [1, 2, 3]}
