This code creates a Java marshaler object and associates it with a proxy. Later, GetMarshaler is used to get the marshaler object:

// Create JavaMarshaler
JavaMarshaler* marshaler = new JavaMarshaler(env,
   proxy, jobj);
 
// Associate the JavaMarshaler with the 
// PowerBuilder proxy
session-> SetMarshaler(proxy, marshaler);
 
ci-> pArgs-> GetAt(0)-> SetObject(proxy);
 
ci-> returnValue-> SetLong(kSuccessful);
 
return PBX_OK;
...
// Get the marshaler
IPBX_Marshaler* pIPBX_Marshaler = NULL;
 
pIPBX_Marshaler =(IPBX_Marshaler*)session
   -> GetMarshaler(proxy);
