Class TempTable

java.lang.Object

org.teiid.query.tempdata.TempTable

All Implemented Interfaces:

Cloneable, SearchableTable

public class TempTable
extends Object
implements Cloneable, SearchableTable

A Teiid Temp Table TODO: in this implementation blocked exceptions will not happen allowing for subquery evaluation though would cause pauses
