org.hibernate.query.sqm.tree.from.SqmFromClause

All Implemented Interfaces:

Serializable, SqmCacheable

public class SqmFromClause
extends Object
implements Serializable, SqmCacheable

Contract representing a from clause.

The parent/child bit represents sub-queries. The child from clauses are only used for test assertions, but are left here as it is most convenient to maintain them here versus another structure.
