public class Thermometer

extends AbstractMeterComponent

This component uses the JFreeChart capabilties to draw a Thermometer.

This class is derived from AbstractMeterComponent which contains many of its methods.

This class uses the MeterModelJFreeChartAdapter class to bridge data from the EchoPoint MeterModel interface to the JFreeChart MeterDatSet interface.

The "axis" used on the Thermometer is controlled by the height of the component. If you make the component higher, more values will be shown on the axis.

Constructor Detail

Thermometer

public Thermometer()

Thermometer constructor.

Method Detail

applyStyle

public void applyStyle(nextapp.echo.Style style)

Applies the provided style to the component. The base nextapp.echo.Component style names can be used as well.

Specified by:

applyStyle in interface MouseCursorable

Overrides:

applyStyle in class AbstractMeterComponent

drawMeterImage

protected nextapp.echo.ImageReference drawMeterImage()

Called to redraw the image for this meter.

Specified by:

drawMeterImage in class AbstractMeterComponent

Returns the color of the Thermometer's mercury area (the bulb)

Returns:

nextapp.echo.Color

getThermometerColor

public nextapp.echo.Color getThermometerColor()

public void setValuePlacement(int newValuePlacement)

Sets the value placement on the Thermometer.

This can be one of the following values:

• Thermometer.VALUE_PLACEMENT_NONE
• Thermometer.VALUE_PLACEMENT_RIGHT
• Thermometer.VALUE_PLACEMENT_BULB

public java.lang.Object set(java.lang.reflect.Field field,
                            java.lang.Object newValue)
                     throws java.lang.Exception

Description copied from interface: ReflectionSetter

Called to save the old value of a field, set in a new value and return the old value of a field. This interface allows a field set operation to be "delegated" back into the class that has permission to perform the field set.

 public Object set(Field f, Object newValue) throws Exception {
      Object oldValue = f.get(this);
      f.set(this,newValue);
      return oldValue;
 }
 

Specified by:

set in interface ReflectionSetter

Overrides:

set in class AbstractMeterComponent

Throws:

java.lang.Exception
