Visitor

Purpose
Allows for one or more operations to be applied to a set of objects at runtime, decoupling the operations from the object structure.

Use When
- An object structure must have many unrelated operations performed upon it.
- The object structure can't change but operations performed on it can.
- Operations must be performed on the concrete classes of an object structure.
- Exposing internal state or operations of the object structure is acceptable.
- Operations should be able to operate on multiple object structures that implement the same interface sets.
