/**
|
|
* A common base class for representing WebIDL callback interface types in C++.
|
|
*
|
|
* This class implements common functionality like lifetime management,
|
|
* initialization with the callback object, and setup of the call environment.
|
|
* Subclasses corresponding to particular callback interface types should
|
|
* provide methods that actually do the various necessary calls.
