- Scenarios that shared_ptr can't solve, e.g. object dependencies are dynamically constructed with no chance to recognize the usage of shared & weak pointers.
- Try to make things simpler compared to shared_ptr and Oilpan, e.g. networking programs using callbacks for async io operations heavily.
- A very good experiment to design a GC dedicated to the C++ language and see how the language features can help.
- Non-intrusive
- Use like shared_ptr.
- Do not need to replace the global new operator.
- Do not need to inherit from a common base.
- Can even work with shared_ptr.
- Generational marking and sweeping
- Can customize the trigger condtion of full gc.
- Can manually delete the object to control the destruction order.
- Super lightweight
- Only one header & CPP file, easier to integrate.
- No extra threads to collect garbage.
- Support most of the containers of STL.
- Cross-platform, no other dependencies, only dependent on STL.
- Customization
- It can work with other memory allocators and pool.
- It can be extended to use your custom containers.
- Precise.
- Ensure no memory leaks as long as objects are correctly traced.
- better throughputs by using generational algorithm
- gc pointers can be global variables
- fast gc pointer construction
- support continuous vector
- unified way to handle class and containers
- gc pointer has smaller size
- do not support multi-inheritance
- can customize the condition of full collection
Please see the tests in 'test.cpp'.
