C++模板庫 libsigc++
libsigc++是實現類型安全回調的一個C++模板庫。
libsigc++提供了信號(signal)和槽(slot)的概念，實現了信號機制。slot對應一個回調函數，信號(signal)與槽(slot)相關聯(attach)，當一個信號被發射(emit)時，相對應的槽被調用。
- Compile time typesafe callbacks (faster than run time checks)
- Typesafety violations report line number correctly with template names (no tracing template failures into headers)
- No compiler extensions or meta compilers required
- Proper handling of dynamic objects and signals (deleted objects will not cause seg faults)
- Extendable API at any level: signal, slot, connection and trackable
- Extensions do not require alteration of basic components
- User definable accumulators
- A variety of adaptors to change the callback signature: bind, hide, retype, compose and lambda call groups
- Various compilers and platforms are supported: gcc, cygwin, mingw32, MS .NET 2003, Sun Forte C++, Compaq C++, Intel C++, IBM AIX, Tru64, IRIX MipsPro.
