Instance Method Details

#get_others(nodes, metadata) ⇒ Object

Get other properties for a given set of nodes. It’s better to not use this method and prefer using methods naming the property being returned. As the nodes_handler can’t know in advance which properties will be returned, it will call it every time there is a missing property. If this method always returns the same values, it would be clever to cache it here.

API

  • This method is optional.

API

  • @platforms_handler can be used.

API

  • @nodes_handler can be used.

API

  • @cmd_runner can be used.

Parameters

  • nodes (Array<String>): The nodes to lookup the property for.

  • metadata (Hash<String, Hash<Symbol,Object> >): Existing metadata for each node. Dependent properties should be present here.

Result

  • Hash<String, Hash<Symbol,Object> >: The corresponding properties, per required node.

    Nodes for which the property can't be fetched can be ommitted.
