value object – Madisoft SpA

Suppose that we have a value object or, more in general, an object where its data has been set in the constructor

class Foo
{
  protected $bar;

  protected $foobar;

  public function construct($bar, $foobar)
  {
    // ....
  }
}

class Foo

{

protected $bar;

protected $foobar;

public function construct($bar, $foobar)

{

// ....

}

and its FormType

class FooType extends AbstractType
{
  public function buildForm(FormBuilderInterface $builder, array $options)
  {
    $builder
      ->add('bar')
      ->add('foobar');
  }
  
  // ...
}

class FooType extends AbstractType

{

public function buildForm(FormBuilderInterface $builder, array $options)

{

$builder

->add('bar')

->add('foobar');

}

// ...

}

Let’s assume that bar and foobar are taken from HTTP POST values (so, basically, we need those values to be posted in order to instantiate a Foo object). Question How can I create…

What this code does?

class DateTimeInterval
{
  private $from;
  private $to;
  private $allDayLong;

  public function setFrom(\DateTime $from)
  {
    if ($this->isAllDayLong()) {
      $from->setTime(0, 0, 0);
    }
    $this->from = $from;

    return $this;
  }

  public function getFrom() { ... } // omitted

  public function setTo(\DateTime $to)
  {
    if ($this->isAllDayLong()) {
      $to->setTime(23, 59, 59);
    }
    $this->to = $to;

    return $this;
  }

  public function getTo() { ... } // omitted
 
  public function allDayLong()
  {
    $this->allDayLong = true;
  } 
 
  public function isAllDayLong()
  {
    return $this->allDayLong;
  }
}

class DateTimeInterval

{

private $from;

private $to;

private $allDayLong;

public function setFrom(\DateTime $from)

{

if ($this->isAllDayLong()) {

$from->setTime(0, 0, 0);

}

$this->from = $from;

return $this;

}

public function getFrom() { ... } // omitted

public function setTo(\DateTime $to)

{

if ($this->isAllDayLong()) {

$to->setTime(23, 59, 59);

}

$this->to = $to;

return $this;

}

public function getTo() { ... } // omitted

public function allDayLong()

{

$this->allDayLong = true;

}

public function isAllDayLong()

{

return $this->allDayLong;

}

It’s a simple class that represent a DateTimeInterval with a flag named allDayLong that let an object of DateTimeInterval class to fill all day. You can see that setFrom and setTo are affected from allDayLong flag: if is set, time of these DateTime are changed in order to fill all day. But…
