Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

This class provides a data structure representing a module’s metadata.

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(name, *args) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Expose any metadata keys as callable reader methods.

Instance Method Details

#add_dependency(name, version_requirement = nil, repository = nil) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Validates the name and version_requirement for a dependency, then creates the Dependency and adds it. Returns the Dependency that was added.

Raises:

  • (ArgumentError)

end

#dashed_name ⇒ Object Also known as: full_module_name

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Returns a filesystem-friendly version of this module name.

#description ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Deprecated.

Provides an accessor for the now defunct ‘description’ property. This addresses a regression in Puppet 3.6.x where previously valid templates referring to the ‘description’ property were broken.

#release_name ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Returns a string that uniquely represents this version of this module.

end

#to_hash ⇒ Object Also known as: to_data_hash

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Returns a hash of the module’s metadata. Used by Puppet’s automated serialization routines.
