Detailed Description
This class is used when calling the raw C PPAPI when using the C++ Var
as a possible NULL exception.
This class will handle getting the address of the internal value out if it's non-NULL and fixing up the reference count.
Warning: this will only work for things with exception semantics, i.e. that the value will not be changed if it's a non-undefined exception. Otherwise, this class will mess up the refcounting.
This is a bit subtle:
- If NULL is passed, we return NULL from get() and do nothing.
- If a undefined value is passed, we return the address of a undefined var from get and have the output value take ownership of that var.
- If a non-undefined value is passed, we return the address of that var from get, and nothing else should change.
Example: void FooBar(a, b, Var* exception = NULL) { foo_interface->Bar(a, b, Var::OutException(exception).get()); }
