DESCRIPTION

Top

This represents a file whose contents will be generated on demand from a callback or method name.

It has one attribute, code, which may be a method name (string) or a coderef. When the file's content method is called, the code is used to generate the content. This content is not cached. It is recomputed every time the content is requested.
