| ) | [pure virtual] |
Report that a value of a "user type" has been encountered in the POF stream.
A user type is analogous to a "class", and a value of a user type is analogous to an "object".
This method call will be followed by a separate call to an "on" or "begin" method for each of the property values in the user type, and the user type will then be terminated by a call to endComplexValue().
| iPos | context-sensitive position information: property index within a user type, array index within an array, element counter within a collection, entry counter within a map, -1 otherwise | |
| nUserTypeId | the user type identifier, (nUserTypeId >= 0) | |
| nVersionId | the version identifier for the user data type data in the POF stream, (nVersionId >= 0) |
Implemented in WritingPofHandler.
| virtual void endComplexValue | ( | ) | [pure virtual] |
Signifies the termination of the current complex value.
Complex values are any of the collection, array, map and user types. For each call to one of the "begin" methods, there will be a corresponding call to this method, even if there were no contents in the complex value.
