Class Method Details

.extract_metadata(vcloud_metadata_entries) ⇒ Hash

Convert the fog metadata into a hash of standard Ruby types Fog and vCloud currently expose the types used in the API, which are unnecessary for most needs. This class maps those custom Fog types back to Ruby types if possible.

Parameters:

  • vcloud_metadata_entries (Hash) —

    vCloud data as returned from Fog

Returns:

  • (Hash) —

    a hash of only the metadata using Ruby types
