Class: YARD::Tags::AttributeDirective

Inherits:
MethodDirective show all
Defined in:
lib/yard/tags/directives.rb

Overview

Note:

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

Note:

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

Defines an attribute with a given name, using indented block data as the attribute's docstring. If the type specifier is supplied with “r”, “w”, or “rw”, the attribute is made readonly, writeonly or readwrite respectively. A readwrite attribute is the default, if no type is specified. 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 a regular method, see @!method

Examples:

Defining a simple readonly attribute

# @!attribute [r] count
#   @return [Fixnum] the size of the list

Defining a simple readwrite attribute

# @!attribute name
#   @return [String] the name of the user
