Method: Wgit::Document#stats

Defined in:
lib/wgit/document.rb

#stats ⇒ Hash Also known as: statistics

Returns a Hash containing this Document's instance variables and their #length (if they respond to it). Works dynamically so that any user defined extractors (and their created instance vars) will appear in the returned Hash as well. The number of text snippets as well as total number of textual bytes are always included in the returned Hash.

Returns:
