| // This file is a supermacro |
| // (see http://wanderinghorse.net/computing/papers/supermacros_cpp.html) to |
| // expand a definition of a late-binding symbol table class. |
| // |
| // Arguments: |
| // LATE_BINDING_SYMBOL_TABLE_CLASS_NAME: Name of the class to generate. |
| // LATE_BINDING_SYMBOL_TABLE_SYMBOLS_LIST: List of symbols to load from the DLL, |
| // as an X-Macro list (see http://www.drdobbs.com/blogs/cpp/228700289). |
| // LATE_BINDING_SYMBOL_TABLE_DLL_NAME: String literal for the DLL file name to |
| // load. |
| // |
| // From a .cc file, include the header file containing your call to the .h.def |
| // supermacro, and then call this supermacro (optionally from inside the |
| // namespace for the class to generate, if any). Example: |
| // |
| // #include "myclassname.h" |
| // |
| // namespace foo { |
| // |
| // #define LATE_BINDING_SYMBOL_TABLE_CLASS_NAME MY_CLASS_NAME |
| // #define LATE_BINDING_SYMBOL_TABLE_SYMBOLS_LIST MY_SYMBOLS_LIST |
| // #define LATE_BINDING_SYMBOL_TABLE_DLL_NAME "libdll.so.n" |
| // #include "talk/base/latebindingsymboltable.cc.def" |
| // |
| // } |
