public EngineName(string projectId, string locationId, string collectionId, string engineId)
Constructs a new instance of a EngineName class from the component parts of pattern
projects/{project}/locations/{location}/collections/{collection}/engines/{engine}
Formats the IDs into the string representation of this EngineName with pattern
projects/{project}/locations/{location}/collections/{collection}/engines/{engine}.
Formats the IDs into the string representation of this EngineName with pattern
projects/{project}/locations/{location}/collections/{collection}/engines/{engine}.
If true will successfully store an unparseable resource name into the UnparsedResource
property; otherwise will throw an ArgumentException if an unparseable resource name is
specified.
