JarCastingGraalvm Annotations
Java Annotations for generating Graalvm ReflectionConfigurationFiles (https://github.com/oracle/graal/blob/master/substratevm/Reflection.md).
Can be used in combination with Gradle Graalvm Annotation Processor.
| Annotation | Description |
|---|---|
| @Reflectable | Can be applied to a class add the class to Graalvm's list of reflection classes to process, (based on https://github.com/oracle/graal/blob/master/substratevm/Reflection.md). |
| @ReflectableClass | Manually configure Graalvm reflection class (based on https://github.com/oracle/graal/blob/master/substratevm/Reflection.md). Can be used on any class you cannot apply the @Reflectable annotation to. |
| @ReflectableClasses | List of ReflectableClass definitions. |
| @ReflectableField | Used with @ReflectableClass to define Graalvm reflection for a class field. |
| @ReflectableMethod | Used with @ReflectableClass to define Graalvm reflection for a class method. |
| @ReflectableImport | Import existing Graalvm 'ReflectionConfigurationFiles' File. |
