/**
 * This interface is a pseudoAPI between Parsing and Indexing support.
 * The Parsing support needs to communicate with Indexing and coordinate task planning.
 * Indexing API can use impl dependency on Parsing API to call the necessary services,
 * but Parsing API must use a bridge implemented by Indexing to call back.
 * 
 * This pseudoAPI can be changed at any time without any warning!
