Sometimes it is needed to manipulate private and protected properties of instances. The common way to do this is to manipule the visibility of the targeted properties using class reflection, but there is a more memory and performance efficient way to accomplish this task.
At first injectors are not standardized nor described along design patterns, i choose Injectors as the name for this mechanic because of their major usage. The explicit technical name could be: IO-Adapters for invisible properties. Injectors do use closure binding with a explicit class scope. So, whatever you want to modify does require knowledge about the implementation details of the targeted parameters, as you should have when directly using closure binding.
