Parameters:   ioChannel - connection to the server. Parameters:   creatingStatement - statement that opened the cursor. Parameters:   metadata - field-level metadata for the results that this cursor covers. Method Detail addRow public void addRow(ResultSetRow row) throws SQLException(Code) Adds a row to this row data. Parameters:   row - the row to add throws:   SQLException - if a database error occurs afterLast public void afterLast() throws SQLException(Code) Moves to after last. throws:   SQLException - if a database error occurs beforeFirst public void beforeFirst() throws SQLException(Code) Moves to before first. throws:   SQLException - if a database error occurs beforeLast public void beforeLast() throws SQLException(Code) Moves to before last so next el is the last el. throws:   SQLException - if a database error occurs close public void close() throws SQLException(Code) We're done. throws:   SQLException - if a database error occurs getAt public ResultSetRow getAt(int ind) throws SQLException(Code) Only works on non dynamic result sets. Parameters:   index - row number to get at row data at index throws:   SQLException - if a database error occurs getCurrentRowNumber public int getCurrentRowNumber() throws SQLException(Code) Returns the current position in the result set as a row number. the current row number throws:   SQLException - if a database error occurs getOwner public ResultSetInternalMethods getOwner()(Code) hasNext public boolean hasNext() throws SQLException(Code) Returns true if another row exists. true if more rows throws:   SQLException - if a database error occurs isAfterLast public boolean isAfterLast()(Code) Returns true if we got the last element. DOCUMENT ME! isBeforeFirst public boolean isBeforeFirst() throws SQLException(Code) Returns if iteration has not occured yet. true if before first row throws:   SQLException - if a database error occurs isDynamic public boolean isDynamic()(Code) Returns true if the result set is dynamic. This means that move back and move forward won't work because we do not hold on to the records. true if this result set is streaming from the server isEmpty public boolean isEmpty() throws SQLException(Code) Has no records. true if no records throws:   SQLException - if a database error occurs isFirst public boolean isFirst() throws SQLException(Code) Are we on the first row of the result set? true if on first row throws:   SQLException - if a database error occurs isLast public boolean isLast() throws SQLException(Code) Are we on the last row of the result set? true if on last row throws:   SQLException - if a database error occurs moveRowRelative public void moveRowRelative(int rows) throws SQLException(Code) Moves the current position relative 'rows' from the current position. Parameters:   rows - the relative number of rows to move throws:   SQLException - if a database error occurs next public ResultSetRow next() throws SQLException(Code) Returns the next row. the next row value throws:   SQLException - if a database error occurs removeRow public void removeRow(int ind) throws SQLException(Code) Removes the row at the given index. Parameters:   index - the row to move to throws:   SQLException - if a database error occurs setCurrentRow public void setCurrentRow(int rowNumber) throws SQLException(Code) Moves the current position in the result set to the given row number. Parameters:   rowNumber - row to move to throws:   SQLException - if a database error occurs setMetadata public void setMetadata(Field[] metadata)(Code) setOwner public void setOwner(ResultSetImpl rs)(Code) size public int size()(Code) Only works on non dynamic result sets. the size of this row data wasEmpty public boolean wasEmpty()(Code) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
