.SH "Detailed Description"
.PP 
The \fBSoCallbackList\fP is a container for callback function pointers\&. 

This list stores callback function pointers (along with user-specified extra data to pass to the callbacks) and provides a method for triggering the callback functions\&. 
.SH "Constructor & Destructor Documentation"
.PP 
.SS "SoCallbackList::SoCallbackList (void )"
Default constructor\&. 
.SS "SoCallbackList::~SoCallbackList (void )"
Destructor\&. 
.SH "Member Function Documentation"
.PP 
.SS "void SoCallbackList::addCallback (SoCallbackListCB * f, void * userdata = \fRNULL\fP)"
Append the callback function \fIf\fP to the list\&. It will be passed the \fIuserdata\fP upon invocation\&. 
.SS "void SoCallbackList::removeCallback (SoCallbackListCB * f, void * userdata = \fRNULL\fP)"
Remove callback \fIf\fP from the list\&. 
.SS "void SoCallbackList::clearCallbacks (void )"
Remove all callbacks in the list\&. 
.SS "int SoCallbackList::getNumCallbacks (void ) const"
Returns number of callback functions\&. 
.SS "void SoCallbackList::invokeCallbacks (void * callbackdata)"
Invoke all callback functions, passing the userdata and the \fIcallbackdata\fP as the first and second argument, respectively\&.

.PP
All callbacks registered when the method is invoked will be triggered, even though if the code in one callback removes another callback\&.

.PP
It is safe for a callback to remove itself or any other callbacks during execution\&.
