Class Method Details

.all(options = { :client => GoodData.connection, :project => GoodData.project }) ⇒ Array<GoodData::MdObject> | Array<Hash>

Method intended to get all objects of that type in a specified project

to pull in full objects. This is desirable from the usability POV but unfortunately has negative impact on performance so it is not the default.

Parameters:

  • options (Hash) (defaults to: { :client => GoodData.connection, :project => GoodData.project }) —

    the options hash

Options Hash (options):

  • :full (Boolean) —

    if passed true the subclass can decide

Returns:

  • (Array<GoodData::MdObject> | Array<Hash>) —

    Return the appropriate metadata objects or their representation
