![]() ![]() the target class is public, the member is public, and the target module use the exports directive from the target package to the caller module.If they are in different modules, the access control can be suppressed only if any of the following conditions are met: Java language access control can be always suppressed by setting the accessible flag to true if the caller class and the target class are in the same module. public members outside their module only if they are declared in an exported package, and the caller module requires their module.protected members only inside their package or subclasses.package members only inside their package.private members only inside their top-level class.boolean trySetAccessible() - sets the accessible flag for this reflected object to true and returns the true if the access control is suppressed and false otherwiseīy default, Java language access control allows the use of:.void setAccessible(boolean flag) - sets the accessible flag for this reflected object to the given boolean value and throws InaccessibleObjectException if the access control cannot be suppressed.boolean canAccess(Object obj) - returns true if and only if the caller can access this reflected object.Here are some methods that this class declares: Accessibility is established using the exports directive in the target module. Readability is established using the requires directive in the caller module.Īccessibility is the basis of strong encapsulation and specifies what packages (and public types in them) the target module exposes to the caller module. ![]() Readability is the basis of reliable configuration and specifies that the caller module can be guaranteed to read types in the target module. Java language access control is connected with two concepts of the Java Platform Module System: readability and accessibility. The AccessibleObject class is an abstract superclass of the Field, Method, and Constructor classes that allows suppressing checks for Java language access control.
