expose: An expose object

In LucyMcGowan/googledrive: An Interface to Google Drive

An expose object

Description

expose() returns a sentinel object, similar in spirit to NULL, that tells the calling function to return its internal data structure. googledrive stores a lot of information about the Drive API, MIME types, etc., internally and then exploits it in helper functions, like drive_mime_type(), drive_fields(), drive_endpoints(), etc. We use these objects to provide nice defaults, check input validity, or lookup something cryptic, like MIME type, based on something friendlier, like a file extension. Pass expose() to such a function if you want to inspect its internal object, in its full glory. This is inspired by the waiver() object in ggplot2.

Usage

expose()

Examples

drive_mime_type(expose())
