For each table specified in Queryable.getConstraintOrderedTableNameClosure() , get
the columns that define the key between the various hierarchy classes. |
protected java.lang.String |

Get the discriminator type |
protected java.lang.String[] |
getKeyColumns(int j)
|
java.io.Serializable[] |
getPropertySpaces()
Returns an array of objects that identify spaces in which properties of this entity are persisted, for instances of this class only. |
