Class: YARD::Tags::MethodDirective

Inherits:
Directive
  • Object
show all
Defined in:
lib/yard/tags/directives.rb

Overview

Note:

This directive should only be used if there is no explicit declaration for the method in any source files (i.e., the method is declared dynamically via meta-programming). In all other cases, add documentation to the method definition itself.

Note:

For backwards compatibility support, you do not need to indent the method’s docstring text. If a @!method directive is seen with no indented block, the entire docstring is used as the new method’s docstring text.

Defines a method object with a given method signature, using indented block data as the method’s docstring. The signature is similar to the @overload tag. The comment containing this directive does not need to be attached to any source, but if it is, that source code will be used as the method’s source.

To define an attribute method, see @!attribute

Examples:

Defining a simple method

# @!method quit(username, message = "Quit")
#   Sends a quit message to the server for a +username+.
#   @param [String] username the username to quit
#   @param [String] message the quit message
quit_message_method

Attaching multiple methods to the same source

# @!method method1
# @!method method2
create_methods :method1, :method2
