Constructor Details

#initialize(namespace, name, scope = :instance, &block) ⇒ MethodObject

Creates a new method object in namespace with name and an instance or class scope

If scope is :module, this object is instantiated as a public method in :class scope, but also creates a new (empty) method as a private :instance method on the same class or module.

Parameters:

  • namespace (NamespaceObject) —

    the namespace

  • name (String, Symbol) —

    the method name

  • scope (Symbol) (defaults to: :instance) —

    :instance, :class, or :module

Dynamic Method Handling

This class handles dynamic methods through the method_missing method in the class YARD::CodeObjects::Base

Instance Attribute Details

#explicit ⇒ Boolean

Whether the object is explicitly defined in source or whether it was inferred by a handler. For instance, attribute methods are generally inferred and therefore not explicitly defined in source.

Returns:

  • (Boolean) —

    whether the object is explicitly defined in source.

def explicit
  @explicit
end

#parameters ⇒ Array<Array(String, String)>

Returns the list of parameters parsed out of the method signature with their default values.

Returns:

#scope ⇒ Symbol

The scope of the method (:class or :instance)

  • (Symbol) —

    the scope

Instance Method Details

#aliases ⇒ Array<Symbol>

Returns all alias names of the object

Returns:

  • (Array<Symbol>) —

    the alias names

  namespace.aliases.each do |o, aname|
    list << o if aname == name && o.scope == scope
  end
  list
end

#attr_info ⇒ SymbolHash?

Returns the read/writer info for the attribute if it is one

Returns:

  • (SymbolHash) —

    if there is information about the attribute

#name(prefix = false) ⇒ String, Symbol

Returns the name of the object.

Parameters:

  • prefix (Boolean) (defaults to: false) —

    whether or not to show the prefix

Returns:

  • (String) —

    returns #sep + name for an instance method if prefix is true

  • (Symbol) —
