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.

Dynamic Method Handling

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

Instance Attribute Details

#explicitBoolean

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.
