Package org.pentaho.reporting.engine.classic.extensions.datasources.mondrian

Class BandedMDXTableModel

java.lang.Object

javax.swing.table.AbstractTableModel

org.pentaho.reporting.engine.classic.extensions.datasources.mondrian.BandedMDXTableModel

All Implemented Interfaces:

Serializable, TableModel, org.pentaho.reporting.engine.classic.core.MetaTableModel, org.pentaho.reporting.engine.classic.core.util.CloseableTableModel

public class BandedMDXTableModel
extends AbstractTableModel
implements org.pentaho.reporting.engine.classic.core.util.CloseableTableModel, org.pentaho.reporting.engine.classic.core.MetaTableModel

This tablemodel performs some preprocessing to get multi-dimensional resultset (with row and column headers) into a classical table-structure. The query must be a two-dimensional query or the whole process will break.

This class exists for legacy reasons to provide existing reports the same view on MDX data as implemented in the Pentaho-Platform and the Report-Designer. It can also be somewhat useful if you have a requirement to produce banded reporting over a MDX data source.

@Deprecated
public BandedMDXTableModel(mondrian.olap.Result resultSet,
                           int rowLimit)

Deprecated.

BandedMDXTableModel

public BandedMDXTableModel(mondrian.olap.Result resultSet,
                           int rowLimit,
                           boolean membersOnAxisSorted)

Method Detail

computeColumnCount

protected int computeColumnCount(int[] axesMembers,
                                 int[] axesSize)

computeRowCount

protected int computeRowCount(int[] axesSize)

computeColumnNames

protected List<String> computeColumnNames(mondrian.olap.Axis[] axes,
                                          List<mondrian.olap.Member> columnToMemberMapper)

getRowCount

public int getRowCount()

Specified by:

getRowCount in interface TableModel

getColumnCount

public int getColumnCount()

Specified by:

getColumnCount in interface TableModel

getColumnName

public String getColumnName(int column)

Returns a default name for the column using spreadsheet conventions: A, B, C, ... Z, AA, AB, etc. If column cannot be found, returns an empty string.

Specified by:

getColumnName in interface TableModel

Overrides:

getColumnName in class AbstractTableModel

Parameters:

column - the column being queried

Returns:

a string containing the default name of column

getValueAt

public Object getValueAt(int rowIndex,
                         int columnIndex)

Specified by:

getValueAt in interface TableModel

getColumnClass

public Class<?> getColumnClass(int columnIndex)

Specified by:

getColumnClass in interface TableModel

Overrides:

getColumnClass in class AbstractTableModel

close

public void close()

Specified by:

close in interface org.pentaho.reporting.engine.classic.core.util.CloseableTableModel

getCellDataAttributes

public org.pentaho.reporting.engine.classic.core.wizard.DataAttributes getCellDataAttributes(int rowIndex,
                                                                                             int columnIndex)

Returns the meta-attribute as Java-Object. The object type that is expected by the report engine is defined in the TableMetaData property set. It is the responsibility of the implementor to map the native meta-data model into a model suitable for reporting.

Meta-data models that only describe meta-data for columns can ignore the row-parameter.

Specified by:

getCellDataAttributes in interface org.pentaho.reporting.engine.classic.core.MetaTableModel

Parameters:

rowIndex - the row of the cell for which the meta-data is queried.

columnIndex - the index of the column for which the meta-data is queried.

Returns:

the meta-data object.

isCellDataAttributesSupported

public boolean isCellDataAttributesSupported()

Specified by:

isCellDataAttributesSupported in interface org.pentaho.reporting.engine.classic.core.MetaTableModel

getColumnAttributes

public org.pentaho.reporting.engine.classic.core.wizard.DataAttributes getColumnAttributes(int column)

Specified by:

getColumnAttributes in interface org.pentaho.reporting.engine.classic.core.MetaTableModel

getTableAttributes

public org.pentaho.reporting.engine.classic.core.wizard.DataAttributes getTableAttributes()

Returns table-wide attributes. This usually contain hints about the data-source used to query the data as well as hints on the sort-order of the data.

Specified by:

getTableAttributes in interface org.pentaho.reporting.engine.classic.core.MetaTableModel

Returns:

the table attributes.
