Class Kitab\Compiler\IntermediateRepresentation\Function_ 

class Function_ extends Kitab\Compiler\IntermediateRepresentation\Entity
{
    public function __construct(string $name);
}

A named function intermediate representation.

A named function is one of the major entity in PHP. It has zero or many inputs, and zero or one output. Each input is represented by a Kitab\Compiler\IntermediateRepresentation\Parameter instance, while the output is represented by a Kitab\Compiler\IntermediateRepresentation\Type instance.

Examples

In this example, a new function f is created with 1 input: int $x, and 1 output: int.

$typeInt = new Kitab\Compiler\IntermediateRepresentation\Type();
$typeInt->name = 'int';

$input1 = new Kitab\Compiler\IntermediateRepresentation\Parameter('x');
$input1->type = $typeInt;

$output = $typeInt;

$function = new Kitab\Compiler\IntermediateRepresentation\Function_('f');
$function->inputs[] = $input1;
$function->output   = $output;
