AlterNotPropertyTrait

Provides an alteration to invert boolean values.

This trait defines a single alteration type Alter::NOT which will invert a boolean value or an array of boolean values. Non-boolean values will be cast to boolean before inversion.

Example usage in AlterDocumentTrait:

$this->alters = [
    'active' => Alter::NOT,          // single boolean
    'flags'  => Alter::NOT,          // array of booleans
];

$data = [
    'active' => true,
    'flags'  => [true, false, true],
];

$result = $this->alter($data);
// $result = [
//     'active' => false,
//     'flags'  => [false, true, false],
// ]

Supported input types:

  • bool → returns the opposite boolean.
  • array<bool> → returns a new array with all elements inverted.
  • any other value → cast to boolean and inverted.
