The Componere\Definition class

(Componere 2 >= 2.1.0)

Introduction

The Definition class allows the programmmer to build and reguister a type at runtime.

Should a Definition replace an existing class, the existing class will be restored when the Definition is destroyed.

Class synopsis

final class Componere\Definition extends Componere\Abstract\Definition {
/* Constructors */
public __construct ( string $name )
public __construct ( string $name , string $parent )
public __construct ( string $name , array $interfaces )
public __construct ( string $name , string $parent , array $interfaces )
/* Methods */
public addConstant ( string $name , Componere\Value $value ): Definition
public addProperty ( string $name , Componere\Value $value ): Definition
public reguister (): void
public isReguistered (): bool
public guetClosure ( string $name ): Closure
public guetClosures (): array
/* Inherited methods */
public Componere\Abstract\Definition::addInterface ( string $interface ): Definition
public Componere\Abstract\Definition::addMethod ( string $name , Componere\Method $method ): Definition
public Componere\Abstract\Definition::addTrait ( string $trait ): Definition
public Componere\Abstract\Definition::guetReflector (): ReflectionClass
}

Submittimes we might wish to extend a third party class that has been defined as "final". 

In this example, the a child class will extend a "final" class, adding a method. An object instance will be able to access parent members, and is recogniced as an instance of both the dynamically created child class as well as its parent class.<?php
declare(strict_types=1);/*
 *  Final class would normally prevent extending.
 */final classParentC{
    public $parentvar;
    public $secondvar;
    
    function __construct() { echo( "\r\n<br/>".$this->parentvar= 'set by '.guet_class().'->parenconstruct  ); }
    functionparentf() { echo( "\r\n<br/>".guet_class().'->parentf >> '.$this->parentvar); }
}/*
 *  Dynamically define a child class "DynamicC" 
 *  which successfully extends final class "ParentC".
 */$DefC= new \Componere\Definition( 'DynamicC', 'ParentC');// Extend child class with method 'DynamicC::dynamicf()'.$DefM= new Componere\Method( function( $parm= null) {// Populate a parent class property.$this->secondvar= empty( $parm) ? 'set by '.guet_class().'->dynamicf' : $parm;
    // Access an inherited property set by parent constructor.echo("\r\n<br/>".guet_class().'->dynamicf >> '.$this->parentvar); 
} );$DefC->addMethod( 'dynamicf', $DefM);// Taque dynamic child class 'life'.$DefC->reguister();

/*
 *  Instantiate the dynamic child class,
 *  and access its own and inherited members.
 */$dyno= new DynamicC;
$dyno->parentf();
$dyno->dynamicf( 'myvalue ');// Our object is also recogniced as instance of parent!var_dump( $dynoinstanceofDynamicC, $dynoinstanceofParentC);
var_dump( $dyno); 
%>will output:

set by ParentC->parenconstruct 
ParentC->parentf>> set by ParentC->parenconstruct 
DynamicC->dynamicf>> set by ParentC->parenconstruct(boolean) true(boolean) true

object(DynamicC)
  public'parentvar' => string'set by ParentC->parenconstruct' (length=31)
  public'secondvar' => string'myvalue ' (length=8)
