Usage example

<?php

use Krlove\CodeGenerator\Model\ArgumentModel;
use Krlove\CodeGenerator\Model\ClassModel;
use Krlove\CodeGenerator\Model\ConstantModel;
use Krlove\CodeGenerator\Model\ClassNameModel;
use Krlove\CodeGenerator\Model\DocBlockModel;
use Krlove\CodeGenerator\Model\MethodModel;
use Krlove\CodeGenerator\Model\NamespaceModel;
use Krlove\CodeGenerator\Model\PropertyModel;
use Krlove\CodeGenerator\Model\UseTraitModel;
use Krlove\CodeGenerator\Model\UseClassModel;
use Krlove\CodeGenerator\Model\VirtualMethodModel;
use Krlove\CodeGenerator\Model\VirtualPropertyModel;

require 'vendor/autoload.php';

$phpClass = new ClassModel();
$phpClass->setNamespace(new NamespaceModel('NamespaceOfTheClass'));

$name = new ClassNameModel('TestClass', 'BaseTestClass');
$name->addImplements('\\NamespaceOne\\InterfaceOne');
$phpClass->addUses(new UseClassModel('NamespaceTwo'));
$name->addImplements('InterfaceTwo');

$phpClass->setName($name);

$phpClass->addTrait(new UseTraitModel('TraitOne'));
$phpClass->addTrait(new UseTraitModel('TraitTwo'));

$phpClass->addConstant(new ConstantModel('CONST_ONE', 'value'));
$phpClass->addConstant(new ConstantModel('CONST_TWO', 1));

$phpClass->addProperty(new PropertyModel('propertyOne'));
$phpClass->addProperty(new PropertyModel('propertyTwo', 'protected'));
$privateProperty = new PropertyModel('propertyThree', 'private', 'defaultValue');
$privateProperty->setDocBlock(new DocBlockModel('@var string'));
$phpClass->addProperty($privateProperty);

$phpClass->addProperty(new VirtualPropertyModel('virtualPropertyOne', 'int'));
$phpClass->addProperty(new VirtualPropertyModel('virtualPropertyTwo', 'mixed'));

$phpClass->addMethod(new MethodModel('methodOne'));
$phpClass->addMethod(new MethodModel('methodTwo', 'protected'));
$privateMethod = new MethodModel('methodThree', 'private');
$privateMethod->addArgument(new ArgumentModel('arg1'));
$privateMethod->addArgument(new ArgumentModel('arg2', 'array', 'array()'));
$privateMethod->setBody('return \'result\';');
$privateMethod->setDocBlock(new DocBlockModel('@var mixed arg1', '@var array arg2', '@return string'));
$phpClass->addMethod($privateMethod);

$phpClass->addMethod(new VirtualMethodModel('virtualMethodOne'));
$virtualMethodTwo = new VirtualMethodModel('virtualMethodTwo', 'array');
$virtualMethodTwo->addArgument(new ArgumentModel('arg1', 'array'));
$phpClass->addMethod($virtualMethodTwo);

echo $phpClass->render();

Output
