    • 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
      Overrides:
      checkCanSetAccessible in class Java8
      Parameters:
      accessibleObject - the accessible object to check
      callerClass - the class wishing to invoke setAccessible
      Returns:
      the check result

      Parameters:
      accessingClass - callerClass the callerClass to invoke setAccessible
      declaringClass - the type of member owner
      memberModifiers - modifiers of member
      allowIllegalAccess - whether to allow illegal access
