# Type

Namespace Chevere\Type

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

# Creating Type

A Type gets created by passing a type keyword.

use Chevere\Type\Type;

$type = new Type(Type::STRING);

# Type keywords

Available keywords:

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

💡 Full-qualified class names and interface names can be passed as type keyword.

# 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`	`SomeClass`
SomeInterface	`interfaceName`	`SomeInterface`

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

# Validator

The validator method provides access to the callable used to primitive validate the type.

use Chevere\Type\Type;

$type = new Type(Type::INTEGER);
$callable = $type->validator();
// is_int

# Validate

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

$boolean = $type->validate($var);

# Check if is scalar

The isScalar method returns true if the type is of type scalar.

use Chevere\Type\Type;

$integerType = new Type(Type::INTEGER);
$true = $integerType->isScalar();
$objectType = new Type(Type::OBJECT);
$false = $type->isScalar();
