Overview

A CaseIgnoringWordList is like a WordList, only that keys are compared case-insensitively.

Ignoring the text case is realized by sending the downcase message to all keys.

Caching usually makes a CaseIgnoringWordList faster, but it has to be activated explicitely.

Constructor Details

#initialize(default = false, caching = false) ⇒ CaseIgnoringWordList

Creates a new case-insensitive WordList with default as default value.

You can activate caching to store the results for every [] request. This speeds up subsequent lookups for the same word, but also uses memory.
