Helper for implementors of entity and collection based query building based on LoadPlans providing common functionality, especially in regards to handling QuerySpace Joins and Fetches.

Exposes 2 main methods:

  1. processQuerySpaceJoins(QuerySpace, SelectStatementBuilder)
  2. processFetches(FetchSource, SelectStatementBuilder, org.hibernate.loader.plan.exec.process.spi.ReaderCollector)li>
