#inventory(propSpecs = {}) ⇒ Hash

TODO:

Return ObjectContent instead of the leaf hash.

Efficiently retrieve properties from descendants of this folder.

Parameters:

  • propSpecs (Hash) (defaults to: {}) —

    Specification of which properties to retrieve from which entities. Keys may be symbols, strings, or classes identifying ManagedEntity subtypes to be included in the results. Values are an array of property paths (strings) or the symbol :all.

Returns:

  • (Hash) —

    Tree of inventory items. Folders are hashes from child name to child result. Objects are hashes from property path to value.
