All Implemented Interfaces:

Serializable
```
public class SqmFromClause
extends Object
implements Serializable
```
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.
