Constructor Detail

Olap4jXmlaQueryExecuter

public Olap4jXmlaQueryExecuter(JasperReportsContext jasperReportsContext,
                       JRDataset dataset,
                       Map<String,? extends JRValueParameter> parametersMap)

Method Detail

getCanonicalQueryLanguage

protected String getCanonicalQueryLanguage()

Description copied from class: JRAbstractQueryExecuter

Returns a canonical query language for this query executer implementation.

The canonical language is used to retrieve extensions for the query executer.

The default implementation returns the runtime query language used in the dataset, but query executer implementations should override this method and return a fixed language.

Overrides:

getCanonicalQueryLanguage in class JRAbstractQueryExecuter

Returns:

a canonical query language

getParameterReplacement

protected String getParameterReplacement(String parameterName)

Description copied from class: JRAbstractQueryExecuter

Returns the replacement text for a query parameter.

Specified by:

getParameterReplacement in class JRAbstractQueryExecuter

Parameters:

parameterName - the parameter name

Returns:

the replacement text

JRQueryChunk.TYPE_PARAMETER

createDatasource

public JRDataSource createDatasource()
                              throws JRException

Description copied from interface: JRQueryExecuter

Executes the query and creates a JRDataSource out of the result.

Returns:

a JRDataSource wrapping the query execution result.

Throws:

JRException

cancelQuery

public boolean cancelQuery()
                    throws JRException

Description copied from interface: JRQueryExecuter

Cancels the query if it's currently running.

This method will be called from a different thread if the client decides to cancel the filling process.

Returns:

true if and only if the query was running and it has been canceled

Throws:

JRException

close

public void close()

Description copied from interface: JRQueryExecuter

Closes resources kept open during the data source iteration.

This method is called after the report is filled or the dataset is iterated. If a resource is not needed after the data source has been created, it should be released at the end of createDatasource.

parseResult

protected void parseResult(org.olap4j.CellSet result)
                    throws JRException

Parses the result into this class's structure

Parameters:

result - The CellSet query result

Throws:

JRException

parseAxes

protected void parseAxes(org.olap4j.CellSet result)

parseCellDataElement

protected void parseCellDataElement(org.olap4j.CellSet result)
                             throws JRException

Throws:

JRException

handleCellErrors

protected void handleCellErrors(org.olap4j.Cell currentCell)
                         throws JRException

Throws:

JRException

handleHierInfo

protected void handleHierInfo(JRXmlaResultAxis xmlaAxis,
                  org.olap4j.CellSetAxisMetaData axisMetaData)

handlePosition

protected void handlePosition(JRXmlaResultAxis axis,
                  org.olap4j.CellSetAxis itAxisElement,
                  org.olap4j.Position p)
