Method: Omnis::Transformer::ClassMethods#property

Defined in:
lib/omnis/transformer.rb

#property(name, expr = nil, opts = {}, &block) ⇒ Object

If an expr is provided it will be passed to the configured extractor, otherwise a block should be given. As last resort, it embeds a lambda to look for a class method with the name of the param (at runtime)
