      • getDefaultImportClasses

        public Map<String,​Set<String>> getDefaultImportClasses​(String[] packageNames)
        Description copied from interface: VMPlugin
        Returns the default import classes: class name -> the relevant package names
        packageNames - the default import package names, e.g. java.lang.
        the default import classes
      • getVersion

        public int getVersion()
        Description copied from interface: VMPlugin
        Gives the version the plugin is made for
        Specified by:
        getVersion in interface VMPlugin
        getVersion in class Java8
        7 for jdk7, 8 for jdk8, 9 for jdk9 or higher
      • checkCanSetAccessible

        public boolean checkCanSetAccessible​(AccessibleObject accessibleObject,
                                             Class<?> callerClass)
        This method may be used by a caller in class C to check whether to enable access to a member of declaring class D successfully if Java8.checkCanSetAccessible(java.lang.reflect.AccessibleObject, java.lang.Class) returns true and any of the following hold:

        1) C and D are in the same module. 2) The member is public and D is public in a package that the module containing D exports to at least the module containing C. 3) The member is protected static, D is public in a package that the module containing D exports to at least the module containing C, and C is a subclass of D. 4) D is in a package that the module containing D opens to at least the module containing C. All packages in unnamed and open modules are open to all modules and so this method always succeeds when D is in an unnamed or open module.

        Specified by:
        checkCanSetAccessible in interface VMPlugin
        checkCanSetAccessible in class Java8

        public boolean trySetAccessible​(AccessibleObject ao)
        Description copied from interface: VMPlugin

        ao - the accessible object
        true if the accessible flag is set to true; false if access cannot be enabled.
