IPB_Session interface:
IsNativeObject method
Description
Determines whether a pbobject is an instance of a native class.
Syntax
IsNativeObject(pbobject obj)Argument |
Description |
|---|---|
obj |
A valid object handle |
Return Values
pbboolean.
Examples
The f_getrow function uses IsNativeObject to test whether extObj is a native class. If so, it gets the native interface and invokes the f_getrowcount function in the other class:
long f_getrow(IPB_Session* session, pbobject dwObj,
pbobject extObj)
{
long lRet;
Imy_pbni* pImy_pbni = NULL;
IPBX_NonVisualObject* pp=NULL;
if (session -> IsNativeObject(extObj) )
{
pp = (IPBX_NonVisualObject*) session ->
GetNativeInterface(extObj);
pImy_pbni = static_cast<Imy_pbni*>(pp);
lRet = pImy_pbni-> f_GetRowCount(session, dwObj);
}
return lRet;
}
Usage
Use this method in conjunction with GetNativeInterface to obtain a direct reference to the IPBX_UserObject associated with another native class, so that the class and its methods can be accessed directly.
