public IndexName(string projectId, string databaseId, string collectionId, string indexId)
Constructs a new instance of a IndexName class from the component parts of pattern
projects/{project}/databases/{database}/collectionGroups/{collection}/indexes/{index}
Formats the IDs into the string representation of this IndexName with pattern
projects/{project}/databases/{database}/collectionGroups/{collection}/indexes/{index}.
Formats the IDs into the string representation of this IndexName with pattern

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.
