#build_option_type_options(opts, options, option_types = []) ⇒ Object

Appends Array of OptionType definitions to an OptionParser instance This adds an option like –fieldContext.fieldName=“VALUE”

Parameters:

  • opts (OptionParser)
  • options (Hash) —

    output map that is being constructed

  • option_types (Array) (defaults to: []) —

    list of OptionType definitions to add

Returns:

  • void, this modifies the opts in place.

This supports the simple remote option eg. ‘instances add –remote “qa”` It will establish a connection to the pre-configured appliance named “qa” The calling command can populate @appliances and/or @appliance_name Otherwise, the current active appliance is used… This returns a new instance of Morpheus::APIClient (and sets @access_token, and @appliance) Your command should be ready to make api requests after this.
