    public interface VMPlugin
    Interface to access VM version based actions. This interface is for internal use only!
    • Method Detail

      • setAdditionalClassInformation

        void setAdditionalClassInformation​(ClassNode c)
      • getPluginDefaultGroovyMethods

        Class[] getPluginDefaultGroovyMethods()
      • getPluginStaticGroovyMethods

        Class[] getPluginStaticGroovyMethods()
      • configureAnnotation

        void configureAnnotation​(AnnotationNode an)
      • invalidateCallSites

        void invalidateCallSites()
      • getInvokeSpecialHandle

        Object getInvokeSpecialHandle​(Method m,
                                      Object receiver)
        Returns a handle with bound receiver to invokeSpecial the given method. This method will require at least Java 7, but since the source has to compile on older Java versions as well it is not marked to return a MethodHandle and uses Object instead
        null in case of jdk<7, otherwise a handle that takes the method call arguments for the invokespecial call
      • invokeHandle

        Object invokeHandle​(Object handle,
                            Object[] args)
                     throws Throwable
        Invokes a handle produced by #getInvokeSpecialdHandle
        handle - the handle
        args - arguments for the method call, can be empty but not null
        the result of the method call
      • getVersion

        int getVersion()
        Gives the version the plugin is made for
        7 for jdk7, 8 for jdk8, 9 for jdk9 or higher
      • checkCanSetAccessible

        boolean checkCanSetAccessible​(AccessibleObject accessibleObject,
                                      Class<?> callerClass)
        Check whether invoking AccessibleObject.setAccessible(boolean) on the accessible object will be completed successfully
        accessibleObject - the accessible object to check
        callerClass - the callerClass to invoke setAccessible
        the check result
      • trySetAccessible

        boolean trySetAccessible​(AccessibleObject ao)
        Set the accessible flag for this reflected object to true if possible.
        ao - the accessible object
        true if the accessible flag is set to true; false if access cannot be enabled.
        SecurityException - if the request is denied by the security manager
      • transformMetaMethod

        MetaMethod transformMetaMethod​(MetaClass metaClass,
                                       MetaMethod metaMethod,
                                       Class<?>[] params,
                                       Class<?> caller)
        transform meta method
        metaClass - meta class
        metaMethod - the original meta method
        params - parameter types
        caller - caller type
        the transformed meta method
