setSeriesType

public void setSeriesType(int type)

Sets the type of the series. Should be one of COLUMN_SERIES or ROW_SERIES.

See Also:

COLUMN_SERIES, ROW_SERIES

getTableModel

public final TableModel getTableModel()

Returns the table model associated to this data source.

setTableModel

public void setTableModel(TableModel tableModel)

Sets the table model associated to this data source.

setMapping

public void setMapping(IlvAbstractTableDataSource.Mapping[] mapping)

Initializes the contents of this data source according to the specified mapping.

Since:

JViews 6.0

getMapping

public IlvAbstractTableDataSource.Mapping[] getMapping()

Returns the contents of this data source according to the specified mapping. May return null if no mapping has been defined.

Since:

JViews 6.0

tableChanged

public void tableChanged(TableModelEvent event)

Handles changes that occur on the table model.

setUndefValue

public void setUndefValue(Double undefValue)

Specifies the undefined value for the data sets of this data source.

Since:

JViews 5.5

See Also:

IlvDataSet.getUndefValue()

getUndefValue

public final Double getUndefValue()

Returns the undefined value for the data sets of this data source.

Returns:

The value specified by the setUndefValue(java.lang.Double) method.

Since:

JViews 5.5

setDefaultConverter

public static void setDefaultConverter(Class<?> dataClass,
                                       IlvDataConverter converter)

Sets the default converter of a data class. The IlvSwingTableDataSource makes use of data converter to convert the objects contained in the TableModel to their corresponding double value. The data source, through its data set, asks the tableModel for the object type (using getColumnClass()), and then tries to find a converter able to handle the object. By default, the IlvSwingTableDataSource registers converters for the following types: Date, String, Short, Integer, Long, Float and Double. Note that the converter for String set through this method has no effect: an IlvStringConverter is used instead that depends on the locale. If you need to handle other kind of objects, you might write a specific IlvDataConverter and register it on the data source.

getDefaultConverter(java.lang.Class<?>), getDataConverter(java.lang.Class<?>), IlvDataConverter

getDefaultConverter

public static IlvDataConverter getDefaultConverter(Class<?> dataClass)

Returns the default converter of the given data class. Since the AbstractTableModel.getColumnClass() method returns Object by default, this method converts Object data using the associated Double converter. Hence, if your data model only contains Double object, overriding getColumnClass() is not mandatory. The method first tries to find the exact mapping of the specified class. If none is found, then it iterates all over the registered data converter and returns the first data converter that can convert the given class, if any.

Returns:

The registered data converter for the specified class, or null if none is found.

setULocale

getLocale()

isTimeSeries

public boolean isTimeSeries(int index)

Returns whether the specified column or row (depending on the type of this data source) represents a time series. The default implementation makes the distinction between ROW_SERIES and COLUMN_SERIES data source:

• For COLUMN_SERIES, it returns true if the class returned by getTableModel().getColumnClass(idx) is an instance of java.util.Date. It returns false otherwise.
• For ROW_SERIES, it returns true if the class returned by getTableModel().getColumnClass(0) is an instance of java.util.Date. It returns false otherwise (that is, it tests only the type of the first column of the model.

Parameters:

index - The index of the column or rows.

JViews 6.0

getDataConverter

public IlvDataConverter getDataConverter(int column)

Returns the data converter for the given column. The default implementation returns the converter associated with the specified column if one exists, otherwise the default converter associated with the data class of the specified column if a TableModel has been set.
