|
* The WZ_DECL_DEPRECATED macro can be used to trigger compile-time warnings
|
|
* with newer compilers when deprecated functions are used.
|
|
*
|
|
* For non-inline functions, the macro gets inserted at front of the
|
|
* function declaration, right before the return type:
|
|
*
|
|
* \code
|
|
* WZ_DECL_DEPRECATED void deprecatedFunctionA();
|
|
* WZ_DECL_DEPRECATED int deprecatedFunctionB() const;
|
|
* \endcode
|
|
*
|
|
* For functions which are implemented inline,
|
|
* the WZ_DECL_DEPRECATED macro is inserted at the front, right before the return
|
|
* type, but after "static", "inline" or "virtual":
|
|
*
|
|
* \code
|
|
* WZ_DECL_DEPRECATED void deprecatedInlineFunctionA() { .. }
|
|
* virtual WZ_DECL_DEPRECATED int deprecatedInlineFunctionB() { .. }
|
|
* static WZ_DECL_DEPRECATED bool deprecatedInlineFunctionC() { .. }
|
|
* inline WZ_DECL_DEPRECATED bool deprecatedInlineFunctionD() { .. }
|
|
* \endcode
|
|
*
|
|
* You can also mark whole structs or classes as deprecated, by inserting the
|
|
* WZ_DECL_DEPRECATED macro after the struct/class keyword, but before the
|
|
* name of the struct/class:
|
|
*
|
|
* \code
|
|
* class WZ_DECL_DEPRECATED DeprecatedClass { };
|
|
