      8 * A common base class for representing WebIDL callback interface types in C++.
      9 *
     10 * This class implements common functionality like lifetime management,
     11 * initialization with the callback object, and setup of the call environment.
     12 * Subclasses corresponding to particular callback interface types should
     13 * provide methods that actually do the various necessary calls.
