Class IndexIdentifier

java.lang.Object

org.apache.cassandra.index.sai.utils.IndexIdentifier

public class IndexIdentifier
extends Object

This is a simple wrapper around the index identity. Its primary purpose is to isolate classes that only need access to the identity from the main index classes. This is useful in testing but also makes it easier to pass the log message wrapper logMessage(String) to classes that don't need any other information about the index.
