Detailed Description
Input object serialization. This interface adds a virtual-object read method to itflow_t. In total - via inheritance - this interface may read objects, primitive types (including streams) and raw bytes.
Member Function Documentation
◆ read_object()
|
pure virtual |
Reads a virtual object from the flow.
The method may succeed (by returning true) and still set out to be null. This is normal, and just means that a null pointer was stored in the stream.
Always pass a real object*. Do not attempt to pass (via a cast) yourobject* to this method. You will be bitten by subtlies in the way C++ moves pointers around on multiple or virtual inheritance heiarchies.
- Parameters
-
out this will be set to the read object
- Returns
- true on success, false on failure.
Implemented in scopira::tool::isoiflow, scopira::tool::propiflow, and scopira::tool::polyiflow.
◆ read_object_type() [1/2]
| bool scopira::tool::iobjflow_i::read_object_type | ( | TT *& | out | ) |
This is a type safe helper around read_object. It will do read_object on its own temporary object* and verify (via assert) that it can be cast to your type TT.
- Parameters
-
out the output pointer to set, may be null on success
- Returns
- true on success
◆ read_object_type() [2/2]
| bool scopira::tool::iobjflow_i::read_object_type | ( | count_ptr< TT > & | out | ) |
Similar to read_object_type, but reads into an auto pointer directly.
