public interface I_CmsMacroResolver
```
Describes a macro mapper, which is used to efficiently resolve macros in the form of %(key) or ${key} in an input String.
Starting with OpenCms 7.0, the preferred form of a macro is %(key). This is to avoid conflicts / confusion with the JSP EL, which also uses the ${key} syntax.
The macro replacement is pre-implemented in CmsMacroResolver.resolveMacros(String, I_CmsMacroResolver).

从以下版本开始:
