The type of linked objects which require to download the description is specified in the Options parameter. If the memory of the computer contains cached descriptions then the method will load them.

If the repository uses the lazy loading of descriptions, then on execution of the method the description of the method is cached in the memory.

However, for the objects for which the IMetabaseObjectDescriptor.IsDeferred attribute is set, the descriptions will not be cached. Working with these objects will be performed by the Fetch* methods.
