Interface RowAccess

Method Details

• setRowIndex

  void setRowIndex(long irow) throws IOException

  Sets the row index to which subsequent data accesses will refer.

  This method must be called before the first invocation of getCell(int)/getRow(), otherwise behaviour is undefined (but implementations will likely throw an unchecked exception on subsequent getCell/getRow calls). The effect of setting the value to an out of range value is undefined; it may throw an exception here, or during subsequent calls, or behave otherwise.

  Parameters:

  irow - row index

  Throws:

  IOException

• getCell

  Object getCell(int icol) throws IOException

  Returns the contents of a given cell at the current row.

  Behaviour is undefined if the row index has not been set, or has been set to a value for which no table row exists; however implementations are encouraged to throw suitable RuntimeException in this case.

  Specified by:

  getCell in interface RowData

  Parameters:

  icol - column index

  Returns:

  contents of given column at current row

  Throws:

  IOException - if there's a problem reading the value

• getRow

  Object[] getRow() throws IOException

  Returns the contents of all the cells at the current row.

  Note the returned object may be reused between invocations,

  Behaviour is undefined if the row index has not been set, or has been set to a value for which no table row exists; however implementations are encouraged to throw a suitable RuntimeException in this case.

  Specified by:

  getRow in interface RowData

  Returns:

  array with one element for each column in the table

  Throws:

  IOException

• close

  void close() throws IOException

  Closes this reader. The effect of calling any of the other methods following a close is undefined.

  Specified by:

  close in interface AutoCloseable

  Specified by:

  close in interface Closeable
