Class SQLReportData

Method Details

• isLabelMapping

  public boolean isLabelMapping()

• getRowCount

  public int getRowCount() throws DataSourceException

  Throws:

  DataSourceException

• isAdvanceable

  public boolean isAdvanceable() throws DataSourceException

  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

  Parameters:

  row -

  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 String getColumnName(int column) throws DataSourceException

  Specified by:

  getColumnName in interface DataSet

  Throws:

  DataSourceException

• get

  public 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
