ReflectionProperty::getSettableType
Returns the parameter type of a setter hook
Description
public ReflectionTypenull ReflectionProperty::getSettableType()
Returns the parameter type of a set hook.
If no set hook is defined, it behaves identically
to ReflectionProperty::getType.
Parameters
This function has no parameters.
Return Values
-
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.
Examples
Example #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());
?>
The above example will output:
object(ReflectionNamedType)#3 (0) {
}
object(ReflectionUnionType)#2 (0) {
}
object(ReflectionNamedType)#3 (0) {
}
NULL
