[Swig-user] Is PHP5 pass-by-reference of class objects supported?

[Teruhiko K. <Ku...@ba...>]

I have a C++ method that obtain an object
as a pointer to it, which has this signature:

bool Foo::GetBar(Bar *&barp);

In C++, this is used as:

Foo *foop =3D new Foo();
Bar *barp;
if(foop->GetBar(barp)){ .... ;barp->someMethod()}

I would like to use Swig so that I could do the same
from PHP5, probably like:

$foo =3D new Foo();
if($foo -> GetBar($bar)){ ... ;$bar->someMethod(); ...}

To achive this, I wrote the Swig interface file as:
%include phppointers.i
%nodefaultctor Bar;
class Bar {
public:
	int someMethod();
}
class Foo {
public:
        bool GetBar(Bar *REF);
}


The generated wrapper files compiled and linked OK.
But when I tried to use it PHP says:
Fatal error: Call to a member function someMethod() on a non-object in
/.../reftest-run.php on line 6
where the offending line is:
$foo =3D new Foo(); // line 4
$foo->GetBar($bar); // line 5
echo "The value is " . $bar->someMethod();=20


In Swig manual section 27.2.5 talks about references but only
about simple types. Is passing a reference to a class object
supported by Swig for PHP5?
