Class CollectionLoadContext

java.lang.Object
  org.hibernate.engine.CollectionLoadContext

public class CollectionLoadContext

extends Object

Represents the state of collections currently being loaded. Eventually, I would like to have multiple instances of this per session - one per JDBC result set, instead of the resultSetId being passed.
