Instance Method Details

#constantize(camel_cased_word) ⇒ Object

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

constantize(“Module”) # => Module constantize(“Test::Unit”) # => 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'
constantize("C") # => 'outside', same as ::C

end

NameError is raised when the constant is unknown.
