Create a new IndexSetChanger

Method Detail

open

public void open(boolean[] fixOnUpdate)
          throws org.apache.derby.iapi.error.StandardException

Open this IndexSetchanger.

---

setRowHolder

public void setRowHolder(TemporaryRowHolderImpl rowHolder)

Set the row holder for all underlying changers to use. If the row holder is set, underlying changers wont bother saving copies of rows needed for deferred processing. Also, it will never close the passed in rowHolder.

---

openIndexes

private void openIndexes(int whatToOpen)
                  throws org.apache.derby.iapi.error.StandardException

Open the indexes that must be fixed if they are not already open.

---

delete

public void delete(org.apache.derby.iapi.sql.execute.ExecRow baseRow,
                   org.apache.derby.iapi.types.RowLocation baseRowLocation)
            throws org.apache.derby.iapi.error.StandardException

Perform index maintenance associated with deleting a row from a table.

---

insert

public void insert(org.apache.derby.iapi.sql.execute.ExecRow baseRow,
                   org.apache.derby.iapi.types.RowLocation baseRowLocation)
            throws org.apache.derby.iapi.error.StandardException

Perform index maintenance associated with insering a row into a table.

---

update

public void update(org.apache.derby.iapi.sql.execute.ExecRow oldBaseRow,
                   org.apache.derby.iapi.sql.execute.ExecRow newBaseRow,

            throws org.apache.derby.iapi.error.StandardException

Perform index maintenance associated with updating a row in a table.

---

setBaseCC

public void setBaseCC(org.apache.derby.iapi.store.access.ConglomerateController baseCC)

Propagate the heap's ConglomerateController to all of the underlying index changers.

---

finish

public void finish()
            throws org.apache.derby.iapi.error.StandardException

Finish processing the changes for this IndexSetChanger. This means doing the deferred inserts for updates of unique indexes.

---

close

public void close()
           throws org.apache.derby.iapi.error.StandardException
