  extended byorg.apache.derby.impl.sql.execute.BasicNoPutResultSetImpl
All Implemented Interfaces:
org.apache.derby.iapi.sql.execute.NoPutResultSet, org.apache.derby.iapi.sql.ResultSet, org.apache.derby.iapi.store.access.RowLocationRetRowSource, org.apache.derby.iapi.store.access.RowSource

abstract class BasicNoPutResultSetImpl
extends java.lang.Object
implements org.apache.derby.iapi.sql.execute.NoPutResultSet

Abstract ResultSet for for operations that return rows but do not allow the caller to put data on output pipes. This basic implementation does not include support for an Activiation. See NoPutResultSetImpl.java for an implementaion with support for an activiation.

This abstract class does not define the entire ResultSet interface, but leaves the 'get' half of the interface for subtypes to implement. It is package-visible only, with its methods being public for exposure by its subtypes.

Method Detail

openCore

public abstract void openCore()
                       throws org.apache.derby.iapi.error.StandardException
Description copied from interface: org.apache.derby.iapi.sql.execute.NoPutResultSet
open a scan on the table. scan parameters are evaluated at each open, so there is probably some way of altering their values...

openCore() can only be called on a closed result set. see reopenCore if you want to reuse an open result set.

Specified by:
openCore in interface org.apache.derby.iapi.sql.execute.NoPutResultSet

reopenCore

public void reopenCore()
                throws org.apache.derby.iapi.error.StandardException
This is the default implementation of reopenCore(). It simply does a close() followed by an open(). If there are optimizations to be made (caching, etc), this is a good place to do it -- this will be overridden by a number of resultSet imlementations. and SHOULD be overridden by any node that can get between a base table and a join.

Specified by:
reopenCore in interface org.apache.derby.iapi.sql.execute.NoPutResultSet

getNextRowCore

public abstract org.apache.derby.iapi.sql.execute.ExecRow getNextRowCore()
                                                                  throws org.apache.derby.iapi.error.StandardException
Description copied from interface: org.apache.derby.iapi.sql.execute.NoPutResultSet
Return the requested values computed from the next row (if any) for which the restriction evaluates to true.

restriction and projection parameters are evaluated for each row.

Specified by:
getNextRowCore in interface org.apache.derby.iapi.sql.execute.NoPutResultSet

getPointOfAttachment

public int getPointOfAttachment()
Description copied from interface: org.apache.derby.iapi.sql.execute.NoPutResultSet
Return the point of attachment for this subquery. (Only meaningful for Any and Once ResultSets, which can and will only be at the top of a ResultSet for a subquery.)

Specified by:
getPointOfAttachment in interface org.apache.derby.iapi.sql.execute.NoPutResultSet

markAsTopResultSet

public void markAsTopResultSet()
Mark the ResultSet as the topmost one in the ResultSet tree. Useful for closing down the ResultSet on an error.

Specified by:
markAsTopResultSet in interface org.apache.derby.iapi.sql.execute.NoPutResultSet

getScanIsolationLevel

public int getScanIsolationLevel()
Description copied from interface: org.apache.derby.iapi.sql.execute.NoPutResultSet
Return the isolation level of the scan in the result set. Only expected to be called for those ResultSets that contain a scan.

Specified by:
getScanIsolationLevel in interface org.apache.derby.iapi.sql.execute.NoPutResultSet

open

public final void open()
                throws org.apache.derby.iapi.error.StandardException
open a scan on the table. scan parameters are evaluated at each open, so there is probably some way of altering their values... NOTE: This method should only be called on the top ResultSet of a ResultSet tree to ensure that the entire ResultSet tree gets closed down on an error. the openCore() method will be called for all other ResultSets in the tree.

Specified by:
open in interface org.apache.derby.iapi.sql.ResultSet

getAbsoluteRow

public org.apache.derby.iapi.sql.execute.ExecRow getAbsoluteRow(int row)
                                                         throws org.apache.derby.iapi.error.StandardException
Returns the row at the absolute position from the query, and returns NULL when there is no such position. (Negative position means from the end of the result set.) Moving the cursor to an invalid position leaves the cursor positioned either before the first row (negative position) or after the last row (positive position). NOTE: An exception will be thrown on 0.

Specified by:

Returns the row at the relative position from the current cursor position, and returns NULL when there is no such position. (Negative position means toward the beginning of the result set.)

getAutoGeneratedKeysResultset

attachStatementContext

                               throws org.apache.derby.iapi.error.StandardException
Attach this result set to the top statement context on the stack. Result sets can be directly read from the JDBC layer. The JDBC layer will push and pop a statement context around each ResultSet.getNext(). There's no guarantee that the statement context used for the last getNext() will be the context used for the current getNext(). The last statement context may have been popped off the stack and so will not be available for cleanup if an error occurs. To make sure that we will be cleaned up, we always attach ourselves to the top context. The fun and games occur in nested contexts: using JDBC result sets inside user code that is itself invoked from queries or CALL statements.

getLanguageConnectionContext

Cache the language connection context. Return it.

Get a compacted version of the candidate row according to the columns specified in the bit map. Share the holders between rows. If there is no bit map, use the candidate row as the compact row.
