Method: Protocol::ProtocolModule#inherit

Defined in:
lib/protocol/protocol_module.rb

#inherit(modul, methodname, block_expected = nil) ⇒ Object

Inherit a method signature from an instance method named methodname of modul. This means that this protocol should understand these instance methods with their arity and block expectation. Note that automatic detection of blocks does not work for Ruby methods defined in C. You can set the block_expected argument if you want to do this manually.
