public interface EndoTerm extends UnaryOperator<Term>
A convenient interface to obtain an endomorphism on `Term`. This is desirable when you need to transform a `Term` into another `Term`. One can specify the `pre` and `post` method which represents a recursive step in pre- and post-order respectively. The overall operation is obtained by recursively transforming the term in pre-order followed by a post-order transformation. Note that the derived `accept` attempts to preserve object identity when possible, hence the implementation of `pre` and `post` can take advantage of this behavior.
