.add_included_callback(othermod) ⇒ Object

These are split in case the included module actually has an :included method defined and the user wants to bootstrap setting up the add_included_callback manually. Note that someone making a module to house a Componentable class is very unlikely to do this, but it could still happen.

.included(othermod) ⇒ Object

In order for Origen to bootstrap using a generic callback, we’ll work a bit backwards. When this module is included by an ‘includer’, it will give

def self.included(othermod)
  add_included_callback(othermod)
end

.init_includer_class(klass_instance) ⇒ Object

Initializes the class that included Componentable (the ‘includer’). All of the singleton methods will be added per Ruby, but the includer still needs to be booted by:

1) Creating and initializing the instance attribute (_componentable_container)
2) Defining a method to get the container directly.
   For example, the Component class will automatically have a :components method that references the
   _componentable_container.

#_add(name, options = {}, &block) ⇒ ComponentableObject

Note:

All options added will be passed to the subclasses instantiation.

Note:

The options is only valid for the stock :add method.

Note:

Any extra options provided are still passed to the subclasses instantiation.

Adds a new item to the componentable container.

Parameters:

  • name (Symbol) —

    Name to reference the new component object.

  • options (Hash) (defaults to: {}) —

    Customizations for both the add method and for the class’s instantiation.

Options Hash (options):

  • class_name (Class, String) —

    The class to instaniate the component at :name as.

Returns:

  • (ComponentableObject) —

    The instantiated class at :name

Raises:

#copy(to_copy, to_location, options = {}) ⇒ Object

Copies the component at :to_copy to :to_location. Default is to deep copy (i.e. clone) the to_copy, resulting in two independent components.

Parameters:

  • to_copy (Symbol) —

    Name of the component to copy.

  • to_location (Symbol) —

    Name to copy to.

  • options (Hash) (defaults to: {}) —

    Customization options.

Options Hash (options):

  • :deep_copy (true, false) — default: true —

    Indicates whether to deep copy (clone) the component or just copy the a reference to the component.

  • :override (true, false) — default: false —

    Indicates if the object at :to_location should be overridden if it already exists.

Raises:

  • (Origen::Componentable::NameInUseError) —

    Raised if :to_location is already in use and the :override option is not specified.

  • (Origen::Componentable::NameDoesNotExistsError) —

    Raised if :to_copy name does not exists.
