# Type

The Type component is in charge of providing a layer for dynamic type handling.

TypeInterface describes the component in charge of defining a type.

# Creating a Type

A Type gets created by passing a $type keyword.

use Chevere\Components\Type\Type;

new Type(Type::STRING);

# Type Keywords

Available keywords defined in TypeInterface:

  • Type::BOOLEAN
  • Type::INTEGER
  • Type::FLOAT
  • Type::STRING
  • Type::ARRAY
  • Type::OBJECT
  • Type::CALLABLE
  • Type::ITERABLE
  • Type::RESOURCE

# Primitive & Type-hinting

The return values for methods primitive and typeHinting is explained in the table below:

Type primitive() typeHinting()
*keyword *keyword *keyword*
SomeClass className ClassName
SomeInterface interfaceName SomeInterface

For keywords, the return value of primitive and typeHinting is same as the actual keyword.

# Validate

The validate method allows to validate any $var against the declared type.

use Chevere\Interfaces\Type\TypeInterface;

 * @var mixed $mixed
 * @var TypeInterface $type
 * @var bool $validate
$validate = $type->validate($mixed);
