ReflectionProperty::getSettableType

Returns the parameter type of a setter hook

説明

public ReflectionTypenull ReflectionProperty::getSettableType()

Returns the parameter type of a set hook. If no set hook is defined, it behaves identically to ReflectionProperty::getType.

パラメータ

この関数にはパラメータはありません。

戻り値

This method returns an instance of ReflectionType that matches the settable type for the property.
If there is a set hook that defines an explicit type, that will be returned.
If the hook does not specify a type, or it does not exist, the property type will be returned, identically to ReflectionProperty::getType. This value may be null if the property is untyped.
If the property is virtual and has no set hook, a ReflectionType instance for never will be returned.

例

例1 ReflectionProperty::getSettableType example

<?php

class Example
{
    public string $basic {
        set => strtolower($value);
    }

    public string $wider {
        set(string|Stringable $value) => (string) $value;
    }

    public string $virtual {
        get => 'Do not change this';
    }

    public $untyped = 'silly';
}

$rClass = new \ReflectionClass(Example::class);

var_dump($rClass->getProperty('basic')->getSettableType());
var_dump($rClass->getProperty('wider')->getSettableType());
var_dump($rClass->getProperty('virtual')->getSettableType());
var_dump($rClass->getProperty('untyped')->getSettableType());

?>

上の例の出力は以下となります。

object(ReflectionNamedType)#3 (0) {
}
object(ReflectionUnionType)#2 (0) {
}
object(ReflectionNamedType)#3 (0) {
}
NULL
