US Patent 10158647 Permissive access control for modular reflection

Access to a module element within a first module by a second module is prohibited if the module element within the first module has not been exposed to the second module. If a particular module element within a first module has been exposed to a second module, then access to the particular module element by the second module may or may not be allowed depending on: (a) whether the particular module element has been declared with a public or non-public access modifier, (b) whether a second exposed module element, which includes the particular module element, has been declared with a public or non-public access modifier, (c) a level of access associated with the operation that attempts to access the particular module element of the first module, and/or (d) whether an accessibility override configuration is set for accessing the particular module element.
