Powerful and fast macro-based data binding engine inspired by Flex Bindings with easy-to-use syntax.

Basic Usage

Bind field

@bindable class Value implements IBindable {
	
	public var a:Int;
	
	// doesn't change setter automatic
	@bindable({force:true}) public var b(get, set):Int;
	
	function get_b():Int {
		return a;
	}
	
	function set_b(v:Int):Int {
		var old = a;
		Bind.notify(this.b, old, a = v); // this.b.notify(old, a = v);
		return a;
	}
	
	public function new() {
		
	}
}

...

using bindx.Bind;
...

var v = new Value();
v.a = 12;

var a = { t:0 };
var unbindTo = v.a.bindxTo(a.t); // a.t == 12

var unbind = v.a.bindx(function (from:Int, to:Int) { trace('v.a changed from:$from to:$to'); } );
v.a = 10; // v.a changed from 12 to 10

unbind();
unbindTo();

// Bind.unbindx - not recursive only
var listener = function (from, to) { trace('$from -> $to'); };
v.a.bindx(listener);
v.a.unbind(listener);

Bind method

using bindx.Bind;

class Value implements IBindable {
	
	@bindable public var a:Int;
	
	@bindable public function toString() {
		return Std.string("Value: a=" + a);
	
	public function update() {
		toString.notify();  // bindx.Bind.notify(this.toString);
	}
	
	public function new() {
		
	}
}

...

using bindx.Bind;
...

var v = new Value();
v.a = 12;

var unbind = v.toString.bindx(function (res:String) { trace(res); } ); // Value: a=12

v.a = 0;
v.update(); // Value: a=0

v.a = 5;
v.toString.notify(); // Value: a=5

unbind();
