Instance Method Details

#full_const_get(name) ⇒ Object

Deprecated.

This method is no longer used by HotCocoa. It will remain in the HotCocoa source for at least version 0.7

Object.full_const_get was taken from the ‘extlib’ project: http://github.com/sam/extlib which is released under a MIT License and copyrighted by Sam Smoot (2008).

Given a string, return the fully qualified constant name found in the receiver's namespace.

Examples:


Object.full_const_get('HotCocoa::Mappings') # => HotCocoa::Mappings
HotCocoa.full_const_get('Mappings') # => HotCocoa::Mappings
