SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
This interface abstracts away how row data is accessed by the result set. It is meant to allow a static implementation (Current version), and a streaming one.
Field Summary | |
static int |
RESULT_SET_SIZE_UNKNOWN
What's returned for the size of a result set when its size can not be determined. |
Method Summary | |
void |
addRow(byte[][] 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. |
byte[][] |
getAt(int index)
Only works on non dynamic result sets. |
int |
getCurrentRowNumber()
Returns the current position in the result set as a row number. |
ResultSet |
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. |
byte[][] |
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 |
setOwner(ResultSet rs)
Set the result set that 'owns' this RowData |
int |
size()
Only works on non dynamic result sets. |
