Obj::isSimpleType() 

\nn\t3::Obj()->isSimpleType($type = ''); 

Checks whether a type (string) is a "simple" type. Simple types are all types apart from models, classes etc. - e.g. array, string, boolean etc.

$isSimple = \nn\t3::Obj()->isSimpleType( 'string' ); // true
$isSimple = \nn\t3::Obj()->isSimpleType( \My\Extname\ClassName::class ); // false

| @return boolean

public function isSimpleType( $type = '' )
{
	return in_array($type, ['array', 'string', 'float', 'double', 'integer', 'int', 'boolean', 'bool']);
}
