Detailed Description

The FunctionObject / DataContainer hiearchy follows the Acyclic Visitor design pattern (see Martin 2002 for more on this).

The base visitor class FunctionObject has no (nontrivial) methods, which breaks the dependency between visitors and visiteds inherent in the GoF Visitor pattern. The meaning of such an object is entirely defined by its use, for which see DataContainer, below, and Vector in Space.H.

Concrete subtypes of FunctionObject will typically apply runtime tests to constrain the types of data container source and target arguments, as well as the number of arguments.
