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.
$ npm install js-to-javavar 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]} Boolean: 'java.lang.Boolean',
boolean: 'boolean',
Integer: 'java.lang.Integer',
int: 'int',
short: 'short',
Short: 'java.lang.Short',
byte: 'byte',
Byte: 'java.lang.Byte',
long: 'long',
Long: 'java.lang.Long',
double: 'double',
Double: 'java.lang.Double',
float: 'float',
Float: 'java.lang.Float',
String: 'java.lang.String',
char: 'char',
chars: 'char[]',
Character: 'java.lang.Character',
List: 'java.util.List',
Set: 'java.util.Set',
Collection: 'java.util.Collection',
Iterator: 'java.util.Iterator',
Enumeration: 'java.util.Enumeration',
HashMap: 'java.util.HashMap',
Map: 'java.util.Map',
Dictionary: 'java.util.Dictionary'abstract class
java.abstract('com.demo.Parent', 'com.demo.Child', { foo: 'bar' });
// => { $abstractClass: 'com.demo.Parent', $class: 'com.demo.Child', $: { foo: 'bar' } }Custom combineFunction:
java.combine('com.test.Object', { foo: 'bar' });
java('com.test.Object', { foo: 'bar' });
// => { $class: 'com.test.Object', $: { foo: 'bar' } }java.Class('java.lang.String');
// => { $class: 'java.lang.Class', $: { name: 'java.lang.String' } }java.Locale('zh_CN', ['com.caucho.hessian.io.LocaleHandle']);
// => { $class: 'com.caucho.hessian.io.LocaleHandle', $: { value: 'zh_CN' } }java.BigDecimal('100.06');
// Or java.BigDecimal({value: '100.06'});
// => { $class: 'java.math.BigDecimal', $: { value: '100.06' } }java.enum('hessian.demo.Color', 'RED');
or
java.enum('hessian.demo.Color', {name: 'RED'});
// => { $class: 'hessian.demo.Color', $: { name: 'RED' } }java.array('Boolean', [true, false]);
// => { $class: '[java.lang.Boolean' $: [true, false] }Available built-in classes shortcuts:
java.array.Boolean(values)java.array.boolean(values)java.array.Integer(values)java.array.int(values)java.array.short(values)java.array.Short(values)java.array.byte(values)java.array.Byte(values)java.array.long(values)java.array.Long(values)java.array.double(values)java.array.Double(values)java.array.float(values)java.array.Float(values)java.array.String(values)java.array.char(values)java.array.chars(values)java.array.Character(values)java.array.List(values)java.array.Set(values)java.array.Iterator(values)java.array.Enumeration(values)java.array.HashMap(values)java.array.Map(values)java.array.Dictionary(values)
default className is java.lang.Exception.
{
'$class': `${className}`,
'$': {
detailMessage: {
'$class': 'java.lang.String',
'$': `${err.name}: ${err.message}`,
},
stackTrace: {
'$class': '[java.lang.StackTraceElement',
'$': stackTraceElements,
},
},
}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}MIT
