MethodReflector

Raxos\Reflection\MethodReflector

Reflects a single class method: its parameters, return type and declaring class, and it can invoke the method on an instance. It uses the Attributable trait for attribute reading and implements SerializableInterface, so a method reference can be serialized and restored.

final readonly class MethodReflector implements ReflectorInterface, SerializableInterface

Both ReflectorInterface and SerializableInterface come from raxos/contract.

Methods

__construct()

public function __construct(ReflectionMethod $method)

Creates a reflector from a native ReflectionMethod. You usually obtain one from a ClassReflector instead of constructing it directly.

getParameters()

public function getParameters(): Generator

Yields a ParameterReflector for each parameter of the method.

getParameter()

public function getParameter(string $name): ?ParameterReflector

Returns a reflector for a single named parameter, or null when it does not exist.

getClass()

public function getClass(): ClassReflector

Returns a ClassReflector for the declaring class.

getReturnType()

public function getReturnType(): ?TypeReflector

Returns a TypeReflector for the declared return type, or null when the method has none.

getName()

public function getName(): string

Returns the method name.

getShortName()

public function getShortName(): string

Returns a readable signature such as User::rename(string $name).

invokeArgs()

public function invokeArgs(?object $instance, array $args = []): mixed

Invokes the method on the given instance with the given arguments. Pass null as the instance for static methods.

Serialization

MethodReflector implements __serialize() and __unserialize(). It serializes to the declaring class name and method name, and restores itself by constructing a fresh ReflectionMethod from that pair. This makes it safe to store a method reference and rebuild it later.

Usage

<?php
declare(strict_types=1);

use function Raxos\Reflection\reflect;

$method = reflect(User::class)->getMethod('rename');

$result = $method->invokeArgs($user, ['Bas']);
