| // libbinder is built with symbol hidden by default. To add a new symbol to the |
| // ABI, you must annotate it with this LIBBINDER_EXPORTED macro. When not |
| // building libbinder (e.g. when another binary includes a libbinder header), |
| // this macro is a no-op. |
| // |
| // Examples: |
| // |
| // // Export a function. |
| // LIBBINDER_EXPORTED void someFunction(); |
| // |
| // // Export a subset of the symbols for a class. |
| // class SomeClassA { |
| // public: |
| // LIBBINDER_EXPORTED SomeClassA(); |
| // |
| // LIBBINDER_EXPORTED SomeMethod(); |
| // } |
| // |
| // // Export all the symbols for a class, even private symbols. |
| // class LIBBINDER_EXPORTED SomeClassB {}; |
| // |
| // For a more detailed explanation of this strategy, see |
| // https://www.gnu.org/software/gnulib/manual/html_node/Exported-Symbols-of-Shared-Libraries.html |

| // headers and accessing these symbols directly. |
