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 interfaceReportData
- Returns:
- Throws:
DataSourceException
-
getColumnCount
- Specified by:
getColumnCount
in interfaceDataSet
- Throws:
DataSourceException
-
setCursorPosition
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 interfaceReportData
- Returns:
- true, if moving the cursor succeeded, false otherwise.
- Throws:
DataSourceException
-
next
Description copied from interface:ReportData
This method produces the same result as 'setCursorPosition(getCursorPosition() + 1);'- Specified by:
next
in interfaceReportData
- Returns:
- Throws:
DataSourceException
-
close
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 interfaceReportData
- Throws:
DataSourceException
-
getColumnName
- Specified by:
getColumnName
in interfaceDataSet
- Throws:
DataSourceException
-
get
- Specified by:
get
in interfaceDataSet
- Throws:
DataSourceException
-
getCursorPosition
- Specified by:
getCursorPosition
in interfaceReportData
- Throws:
DataSourceException
-
isReadable
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 interfaceReportData
- Returns:
- true, if the datarow is valid, false otherwise.
- Throws:
DataSourceException
