org.teiid.query.mapping.relational.QueryNode

The QueryNode represents a virtual or temporary group in the modeler. QueryNodes may be nested to indicate data queries built from other virtual or temporary groups. The root node of a tree of QueryNode objects should be defining a virtual group. Leaves should be other physical or virtual groups. Internal nodes of the tree are temporary groups.

A QueryNode must have a group name and a query. It may have a command (just used for convenient storage during conversion - this is not persisted).
