| Constructor Summary | |

| Method Summary | |
| public void | close()
If the result set has been opened,
close the open scan. | | public ExecRow | getCurrentRow()
Gets last row returned. | | public ExecRow | getNextRowCore()
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.
exception:
StandardException - thrown on failure.
exception:
StandardException - ResultSetNotOpen thrown if not yet open. | | public DataValueDescriptor[] | getNextRowFromRowSource()
| | public RowLocation | getRowLocation()
Gets information from its source. | | public long | getTimeSpent(int type)
Return the total amount of time spent in this ResultSet
Parameters:
type - CURRENT_RESULTSET_ONLY - time spent only in this ResultSetENTIRE_RESULTSET_TREE - time spent in this ResultSet and below. | | public boolean | isForUpdate()
| | public void | openCore()
open a scan on the table. | | public void | reopenCore()
reopen a scan on the table. |
| hashtableSize | | public int hashtableSize(Code) | | |
| keyColumns | | public int[] keyColumns(Code) | | |
| projectionTime | | public long projectionTime(Code) | | |
| restrictionTime | | public long restrictionTime(Code) | | |
| reuseResult | | public boolean reuseResult(Code) | | |
| HashTableResultSet | | HashTableResultSet(NoPutResultSet s, Activation a, GeneratedMethod str, Qualifier[][] nextQualifiers, GeneratedMethod p, int resultSetNumber, int mapRefItem, boolean reuseResult, int keyColItem, boolean removeDuplicates, long maxInMemoryRowCount, int initialCapacity, float loadFactor, boolean skipNullKeyColumns, double optimizerEstimatedRowCount, double optimizerEstimatedCost) throws StandardException(Code) | | |
| getNextRowCore | | public ExecRow getNextRowCore() throws StandardException(Code) | | 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.
exception:
StandardException - thrown on failure.
exception:
StandardException - ResultSetNotOpen thrown if not yet open. the next row in the result |
| getRowLocation | | public RowLocation getRowLocation() throws StandardException(Code) | | Gets information from its source. We might want
to have this take a CursorResultSet in its constructor some day,
instead of doing a cast here?
See Also: CursorResultSet the row location of the current cursor row.
exception:
StandardException - thrown on failure. |
| getTimeSpent | | public long getTimeSpent(int type)(Code) | | Return the total amount of time spent in this ResultSet
Parameters:
type - CURRENT_RESULTSET_ONLY - time spent only in this ResultSetENTIRE_RESULTSET_TREE - time spent in this ResultSet and below. long The total amount of time spent (in milliseconds). |
| isForUpdate | | public boolean isForUpdate()(Code) | | Is this ResultSet or it's source result set for update
Whether or not the result set is for update. |
| openCore | | public void openCore() throws StandardException(Code) | | open a scan on the table. scan parameters are evaluated
at each open, so there is probably some way of altering
their values...
exception:
StandardException - thrown if cursor finished. |
| reopenCore | | public void reopenCore() throws StandardException(Code) | | reopen a scan on the table. scan parameters are evaluated
at each open, so there is probably some way of altering
their values...
exception:
StandardException - thrown if cursor finished. |
