Columnset[] |
generateColumnSetsForOp(boolean lazy)
Abstract method to be implemented by subclasses. |
abstract java.lang.String |
generateSQLDefinition(java.lang.String selectPart)
This method must return the SQL definition of the newly created ColumnSet. |

generateSQLDefinition(java.lang.String selectPart,
int index)
This method must return the SQL definition of the newly created ColumnSet. |
java.lang.String |
getNewCSName()
For a SingleConcept operator the index is always -1,
so this method can be defined without an argument. |
abstract java.lang.String |
getTypeOfNewColumnSet()
This method must return the entry String for the M4 table "Columnset_t", indicating whether the new Columnset is a view or a table. |
