GitHub - node-modules/js-to-java: easy way to wrap js object to java object

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.

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]}

java.abstract(abstractClassname, classname, value)

abstract class

java.abstract('com.demo.Parent', 'com.demo.Child', { foo: 'bar' });
// => { $abstractClass: 'com.demo.Parent', $class: 'com.demo.Child', $: { foo: 'bar' } }

java[.combine](classname, value)

Custom combineFunction:

java.combine('com.test.Object', { foo: 'bar' });
java('com.test.Object', { foo: 'bar' });
// => { $class: 'com.test.Object', $: { foo: 'bar' } }

java.Class(classname)

java.Class('java.lang.String');
// => { $class: 'java.lang.Class', $: { name: 'java.lang.String' } }

java.Locale(locale, handle)

java.Locale('zh_CN', ['com.caucho.hessian.io.LocaleHandle']);
// => { $class: 'com.caucho.hessian.io.LocaleHandle', $: { value: 'zh_CN' } }

java.BigDecimal(decimal)

java.BigDecimal('100.06');
// Or java.BigDecimal({value: '100.06'});
// => { $class: 'java.math.BigDecimal', $: { value: '100.06' } }

java.enum(classname, value)

java.enum('hessian.demo.Color', 'RED');
  or
java.enum('hessian.demo.Color', {name: 'RED'});
// => { $class: 'hessian.demo.Color', $: { name: 'RED' } }

java.array(classname, values)

java.array('Boolean', [true, false]);
// => { $class: '[java.lang.Boolean' $: [true, false] }

Available built-in classes shortcuts:

java.array.Boolean(values)
java.array.boolean(values)
java.array.Integer(values)
java.array.int(values)
java.array.short(values)
java.array.Short(values)

java.exception(err[, className])

default className is java.lang.Exception.

{
  '$class': `${className}`,
  '$': {
    detailMessage: {
      '$class': 'java.lang.String',
      '$': `${err.name}: ${err.message}`,
    },
    stackTrace: {
      '$class': '[java.lang.StackTraceElement',
      '$': stackTraceElements,
    },
  },
}

java.revert(obj)

Wrap java object back to js object reversely.

var data = {
  $class: 'xxxx',
  $: {
    foo: 'bar',
    bar: {
      $class: 'int',
      $: 3,
    },
  },
};
java.revert(data);
// => {foo: 'bar', bar: 3}
