Class Method Details

.full_type ⇒ Object

Returns the source name as a “/” delimited string of all the module and class names following “Licensed::Sources::”. This is the type that is used to distinguish multiple versions of a sources from each other. e.g. for ‘Licensed::Sources::Yarn::V1`, this returns `yarn/v1`

def inherited(klass)
  # register the inherited class as a source on the Licensed::Sources::Source class

end

def register_source(klass)
  # add the source class to the known sources list
  return unless klass < Licensed::Sources::Source
  (@sources ||= []) << klass
end

.type ⇒ Object

Returns the source name as the first snake cased class or module name following “Licensed::Sources::”. This is the type that is included in metadata files and cache paths. e.g. for ‘Licensed::Sources::Yarn::V1`, this returns “yarn”

# File 'lib/licensed/sources/source.rb', line 31

def type
  type_and_version[0]
end

.type_and_version ⇒ Object

Returns an array that includes the source’s type name at the first index, and optionally a version string for the source as the second index. Callers should override this function and not ‘type` or `full_type` when needing to adjust the default type and version parsing logic
