Interface Regular.Folder<V>

Type Parameters:

V - the resulting type of applying this folder

Enclosing class:

Regular

public static interface Regular.Folder<V>

An instance of Regular.Folder is a set of methods to apply to the various cases of a regular expression, depending on its form, as part of a (possibly) recursive traversal of the regular expression structure. It is the natural catamorphism of the tree-like structure of regular expressions, and a generalization of the traditional Java visitor.
