Make the ConstantAction for a CREATE INDEX statement.

Method Detail

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

executeConstantAction

public void executeConstantAction(org.apache.derby.iapi.sql.Activation activation)
                           throws org.apache.derby.iapi.error.StandardException

This is the guts of the Execution-time logic for CREATE INDEX.

---

getIndexTemplateRow

org.apache.derby.iapi.sql.execute.ExecRow getIndexTemplateRow()

---

statementExceptionCleanup

private void statementExceptionCleanup(org.apache.derby.iapi.store.access.ScanController scan,
                                       org.apache.derby.iapi.store.access.ConglomerateController indexController)
                                throws org.apache.derby.iapi.error.StandardException

Do necessary clean up (close down controllers, etc.) before throwing a statement exception.

loadSorter

private org.apache.derby.iapi.store.access.RowLocationRetRowSource loadSorter(org.apache.derby.iapi.sql.execute.ExecRow[] baseRows,
                                                                              org.apache.derby.iapi.sql.execute.ExecIndexRow[] indexRows,
