Family of Callback Wrappers allowing to store chains of delayed calls that can be started by event.

* FunctionCallback - calls global function or static method.

* MethodCallback - calls instance or static method.

* OutputCallback - outputs all arguments in JSON format.

* PropertyCallback - stores first argument as property value, works with static properties.

* VariableCallback - stores first argument as variable value, works with static properties.

* CallableQueue - calls stored callbacks passing previous result as argument, returns result of last callback.

* CallableSequence - calls stored callbacks with same arguments, returns result of last callback.

```php

$variable = 'value';

$callback = new \aw\callbacks\VariableCallback('variable');

$callback('new value');

echo $variable.PHP_EOL; // new value

function doEcho($param){

  echo 'My name is: '.$param.PHP_EOL;

}

$callback = new \aw\callbacks\FunctionCallback('doEcho');

$callback('####'); // My name is: ####

```

### Installation

Via [composer](https://getcomposer.org/)

```

composer require actualwave/callbacks

```

### Usage

All wrappers are callables, so can be used directly as closure.

CallableCollection accepts any callable including PHP closures.

```php

function multiply4($value){

  return $value*4;

}

$collection = new \aw\CallableQueue();

$collection[] = function($value){

  return $value*2;

};

$collection[] = function($value){

  return $value*3;

};

$collection[] = new \aw\callbacks\FunctionCallback('multiply4');

echo 'Result: '.$collection(2).PHP_EOL; // Result: 48

```
