constantize

v2.1.0 - Show latest stable - 1 note - Class: Inflector
constantize(camel_cased_word) public

Tries to find a constant with the name specified in the argument string:

  "Module".constantize     # => Module
  "Test::Unit".constantize # => Test::Unit

The name is assumed to be the one of a top-level constant, no matter whether it starts with "::" or not. No lexical context is taken into account:

  C = 'outside'
  module M
    C = 'inside'
    C               # => 'inside'
    "C".constantize # => 'outside', same as ::C
  end

NameError is raised when the name is not in CamelCase or the constant is unknown.
