Nested Class Summary

protected static class	ChartObjectHandler.DateTickUnitBean Utility class to build up the parameters for a DateTickUnit.
protected static class	ChartObjectHandler.InsetBean Utility class to build up the parameters for a RectangleInset.
protected static class	ChartObjectHandler.ItemLabelPositionBean Utility class to build up the parameters for a ItemLabelPosition.
protected static class	ChartObjectHandler.NumberTickUnitBean Utility class to build up the parameters for a NumberTickUnit.
protected static class	ChartObjectHandler.PeriodAxisLabelInfoBean Utility class to build up the parameters for a PeriodAxisLabelInfo.

Field Summary

static java.lang.String	DATE_TICK_UNIT Creates a custom configuration for DateTickUnit since that class does not have a default constructor.

static java.lang.String	ITEM_LABEL_POSITION Creates a custom configuration for ItemLabelPosition.
protected static Log	log
static java.lang.String	NUMBER_TICK_UNIT Creates a custom configuration for NumberTickUnit since that class does not have a default constructor.
static java.lang.String	PERIOD_AXIS_LABEL_INFO Creates a PeriodAxisLabelInfo.
static java.lang.String	TIME_TOOL_TIP Creates a StandardXYToolTipGenerator that properly formats time values for the X coordinate.

log

protected static final Log log

TIME_TOOL_TIP

public static final java.lang.String TIME_TOOL_TIP

Creates a StandardXYToolTipGenerator that properly formats time values for the X coordinate.

DATE_TICK_UNIT

public static final java.lang.String DATE_TICK_UNIT

Creates a custom configuration for DateTickUnit since that class does not have a default constructor.

Constant Field Values

NUMBER_TICK_UNIT

public static final java.lang.String NUMBER_TICK_UNIT

Creates a custom configuration for NumberTickUnit since that class does not have a default constructor.

Constant Field Values

ITEM_LABEL_POSITION

public static final java.lang.String ITEM_LABEL_POSITION

Creates a custom configuration for ItemLabelPosition. You can do much of what this does with several individual renderer properties (like setItemLabelRotationAnchor or setItemLabelAngle). This custom tag just nicely groups things together.

Constant Field Values

PERIOD_AXIS_LABEL_INFO

public static final java.lang.String PERIOD_AXIS_LABEL_INFO

Creates a PeriodAxisLabelInfo. You will most likely need the INSET and ARRAY_PROPERTY tags as well.

PeriodAxisLabelInfo, Constant Field Values

INSET

public static final java.lang.String INSET

Creates a RectangleInset object.

We only handle a few specific tags.

Specified by:

Overrides:

createObject

public java.lang.Object createObject(java.lang.String tag,
                                     org.xml.sax.Attributes atts,
                                     ObjectXmlReader reader)

Creates and returns an object based on the specified parameters.

Specified by:

Overrides:

resolveObject

public java.lang.Object resolveObject(java.lang.String tag,
                                      java.lang.Object obj,
                                      ObjectXmlReader reader)

Description copied from class: AbstractObjectHandler

Converts a handler-specific internal representation of an object to a standard representation. This is an implementation specific thing since some handlers will collect attributes/properties in an intermediate object. When the end of the tag is reached, the ObjectXmlReader will call this method to perform and necessary translations. Handlers that don't require resolution should just return the passed object. Default implementation returns obj.

Specified by:

resolveObject in interface ObjectHandler

Overrides:

resolveObject in class AbstractObjectHandler
