Description
This is a base class for all BINARY INPUT streams, in a way such that the stream is platform independent (see the 'little endian' stuff in 'floating point to persistent data' topics..) Defines some << operators from basic types, converting all them into calls to the Output() function.
At least some inherited class should be used by the user in order to get some practical effect (file saving, etc.)

Member Function Documentation
◆ AbstractReadAllCreate()
|
inline |
Extract an object from the archive, and assigns the pointer to it.
This function can be used to load objects whose class is not known in advance (anyway, assuming the class had been registered with Chrono class factory registration). It creates the object of the proper downcasted class, and deserializes it. Note: the object must be saved with ChStreamOutBinary::AbstractWrite() Also, the AbstractWrite()-AbstractReadCreate() mechanism avoids storing/creating multiple times the shared objects. Supports only objects with Chrono RTTI and serializer member StreamIN().
◆ AbstractReadCreate()

◆ operator>>()
| ChStreamInBinary & chrono::ChStreamInBinary::operator>> | ( | char & | Val | ) |
Specialized operators for basic primitives (numbers like long, double, int.
etc., and booleans) Handle byte ordering issues in little.endian/big.endian representations, for cross platform portability.
