PHP IDE :: NuSphere Forums :: View topic - Code completion for singleton pattern *resolved*

Posted: Tue Dec 05, 2006 9:09 am

Hello,

Code completion does not seem to work with the following singleton pattern:

Code:

class singleton
{
function &getInstance ($class)
// implements the 'singleton' design pattern.
{
static $instances = array(); // array of instance names

if (!array_key_exists($class, $instances)) {
// instance does not exist, so create it
$instances[$class] = new $class;
} // if

$instance =& $instances[$class];

return $instance;

} // getInstance

} // singleton

require_once 'std.datevalidation.class.inc';
$dateobj =& singleton::getInstance('DateClass');

$dateobj-> does not pull up any function list.

Is there a way to get this code completion to work? Will it work in a future version? Thanks.

type of object instance returned by that class is known only at run-time and therefore to get code completion working you need to add type hint.

that doesn't seem to address the original problem, which i am now running in to.

in class tm, i have a singleton generator. $newobj = tm::generate_singleton('user');. at this point, $newobj contains an object of class 'user'. however, phped thinks that $newobj is in the tm class instead. i can't use the phpdoc "returns" syntax since the object type varies depending on how the function is called. is there any resolution for this?

Code:

/** @var user */
$newobj = tm::generate_singleton('user');
