Method Detail

hasNextRow

boolean hasNextRow()

Determines if there is another row in the current data source

Returns:

true if this is not the last cell in the row, false if it is the last

nextRow

boolean nextRow()
         throws IOException

Moves the reader on to the next row in the data source. If row by row and there are any unread cells in the current row these will be unread

Returns:

true if this is not the last cell in the row, false if it is the last

Throws:

IOException - if the data source can not be read

hasNextColumn

boolean hasNextColumn()

Determines if there another cell in the current column

Returns:

true if this is not the last cell in the column, false if it is the last

nextColumn

boolean nextColumn()
            throws IOException

Moves the reader on to the next cell in the column. If reading column by column and there are any unread cells in the current column these will be unread

Returns:

true if this is not the last cell in the column, false if it is the last

Throws:

IOException - if the data source can not be read
