The expression
return false returns the type false which is incompatible with the return type mandated by SilverStripe\CronTask\In...ces\CronTask::process() of void.
In the issue above, the returned value is violating the contract defined by the mentioned interface. Let's take a look at an example: interface HasName {
/** @return string */
public function getName();
}
class Name {
public $name;
}
class User implements HasName {
/** @return string|Name */
public function getName() {
return new Name('foo'); // This is a violation of the ``HasName`` interface
// which only allows a string value to be returned.
}
