public class TableFactory

extends ChartFactory

TableFactory implements a table chart that produces various XML markup table dumps of chart data. The factory supports a number of different markup languages, each implemented in it's own TableRenderer class. The following XML markup flavors are supported by default:

• text/html - HTMLTableRenderer
• text/xsl+xml - FOTableRenderer
• text/vnd.davisor.xsl+xml - FOEmulatorTableRenderer

The output markup flavor is selected by the desired chart content type, as returned by ChartAttributes.getContentType(). Unrecognized types and types unsuitable for text output default to text/html.

All actual rendering work is done by the selected table renderer. Please see AbstractTableRenderer for more information about the capabilities of the default renderers.

Since:

JDK1.4

Method Detail

createContext

public ChartFactory.ChartContext createContext(ChartData data,
                                               ChartAttributes attr)
                                        throws ChartException

Creates and initializes a table chart context.

Specified by:

createContext in class ChartFactory

Parameters:

data - chart data

attr - chart attributes

Returns:

chart context, containing chart sizing information

Throws:

ChartException - if chart generation fails

See Also:

createMetrics(com.davisor.graphics.chart.ChartFactory.ChartContext, com.davisor.graphics.chart.ChartAttributes)

createMetrics

public ChartFactory.ChartMetrics createMetrics(ChartFactory.ChartContext context,
                                               ChartAttributes attr)
                                        throws ChartException

Resolves final chart image and image component sizes.

Specified by:

createMetrics in class ChartFactory

Parameters:

context - chart context

attr - chart attributes

Returns:

null always

Throws:

ChartException - if chart generation fails

createChart

public Chart createChart(ChartFactory.ChartContext chartContext,
                         ChartFactory.ChartMetrics chartMetrics,
                         ChartAttributes attr,
                         Chart chart)
                  throws ChartException

Draws chart using information in ChartContext and ChartMetrics. This method resolves requested chart content type, creates a new chart instance if neccessary, and then delegates the rendering task to an appropriate TableRenderer instance.

If there is no table renderer for given content type, a warning message is printed in system log, and the unrendered chart object is returned as it is.

Specified by:

createChart in class ChartFactory

Parameters:

chartContext - context information

chartMetrics - metrics information

attr - chart attributes

chart - chart to be drawn into (may be null)

Returns:

the given chart instance or a new one if none was given

Throws:

ChartException - if chart generation fails

getContentType(), AbstractTableRenderer, TableRenderer

getContentType

public java.lang.String getContentType()

Gets the content type preferred by this factory.

Overrides:

getContentType in class ChartFactory

Returns:

"text/html"

dup

public com.davisor.core.Dupable dup()

Duplicates this factory.
