```
public boolean isAdvanceable()

```
    This operation checks, whether a call to next will be likely to succeed. If there is a next data row, this should return true.
    
    Specified by:
    
    isAdvanceable in interface ReportData
    
    Returns:
    
    Throws:
    
    DataSourceException
  - getColumnCount
```
public int getColumnCount()
                   throws DataSourceException
```
    Specified by:
    
    getColumnCount in interface DataSet
    
    Throws:
    
    DataSourceException
  - setCursorPosition
```
public boolean setCursorPosition(int row)
                          throws DataSourceException
```
    Description copied from interface: ReportData
    
    Moves the cursor back to an already visited position. Calling this method for an row number that has not yet been read using 'next' is undefined, whether that call succeeds is implementation dependent. Calls to position zero (aka BEFORE_FIRST_ROW) will always succeeed (unless there is a physical error, which invalidated the whole report-data object).
    
    Specified by:
    
    setCursorPosition in interface ReportData
    
    Returns:
    
    true, if moving the cursor succeeded, false otherwise.
    
    Throws:
    
    DataSourceException
  - next
```
public boolean next()
             throws DataSourceException
```
    Description copied from interface: ReportData
    
    This method produces the same result as 'setCursorPosition(getCursorPosition() + 1);'
    
    Specified by:
    
    next in interface ReportData
    
    Returns:
    
    Throws:
    
    DataSourceException
  - close
```
public void close()
           throws DataSourceException
```
    Description copied from interface: ReportData
    
    Closes the datasource. This should be called at the end of each report processing run. Whether this closes the underlying data-source backend depends on the ReportDataFactory. Calling 'close()' on the ReportDataFactory *must* close all report data objects.
    
    Specified by:
    
    close in interface ReportData
    
    Throws:
    
    DataSourceException
  - getColumnName
```
public java.lang.String getColumnName(int column)
                               throws DataSourceException
```
    Specified by:
    
    getColumnName in interface DataSet
    
    Throws:
    
    DataSourceException
  - get
```
public java.lang.Object get(int column)
                     throws DataSourceException
```
    Specified by:
    
    get in interface DataSet
    
    Throws:
    
    DataSourceException
  - getCursorPosition
```
public int getCursorPosition()
                      throws DataSourceException
```
    Specified by:
    
    getCursorPosition in interface ReportData
    
    Throws:
    
    DataSourceException
  - isReadable
```
public boolean isReadable()
                   throws DataSourceException
```
    Description copied from interface: ReportData
    
    Checks, whether this report-data instance is currently readable. A report-data instance cannot be readable if it is positioned before the first row. (The look-ahead system of 'isAdvanceable()' will prevent that the datasource is positioned behind the last row.)
    
    Specified by:
    
    isReadable in interface ReportData
    
    Returns:
    
    true, if the datarow is valid, false otherwise.
    
    Throws:
    
    DataSourceException
