Modifier and Type | Method and Description |
---|---|
void |
addRow(ResultSetRow row)
Adds a row to this row data.
|
void |
afterLast()
Moves to after last.
|
void |
beforeFirst()
Moves to before first.
|
void |
beforeLast()
Moves to before last so next el is the last el.
|
void |
close()
We're done.
|
ResultSetRow |
getAt(int index)
Only works on non dynamic result sets.
|
int |
getCurrentRowNumber()
Returns the current position in the result set as a row number.
|
ResultSetInternalMethods |
getOwner()
Returns the result set that 'owns' this RowData
|
boolean |
hasNext()
Returns true if another row exsists.
|
boolean |
isAfterLast()
Returns true if we got the last element.
|
boolean |
isBeforeFirst()
Returns if iteration has not occured yet.
|
boolean |
isDynamic()
Returns true if the result set is dynamic.
|
boolean |
isEmpty()
Has no records.
|
boolean |
isFirst()
Are we on the first row of the result set?
|
boolean |
isLast()
Are we on the last row of the result set?
|
void |
moveRowRelative(int rows)
Moves the current position relative 'rows' from the current position.
|
ResultSetRow |
next()
Returns the next row.
|
void |
removeRow(int index)
Removes the row at the given index.
|
void |
setCurrentRow(int rowNumber)
Moves the current position in the result set to the given row number.
|
void |
setMetadata(Field[] metadata)
Sometimes the driver doesn't have metadata until after
the statement has the result set in-hand (because it's cached),
so it can call this to set it after the fact.
|
void |
setOwner(ResultSetImpl rs)
Set the result set that 'owns' this RowData
|
int |
size()
Only works on non dynamic result sets.
|
boolean |
wasEmpty()
Did this result set have no rows?
