Constructor Detail

MeasurementMonitor

protected MeasurementMonitor()

Creates a new instance of MeasureMonitor

Method Detail

setLabel

public void setLabel(Label label)

Sets the Label of the monitor that is to display the measurement.

Parameters:

label -

selectItem

public void selectItem(ComponentElement item)

Puts the item to the selection and clears its description. It is necessary to have proper measurement labels, because in case of predefined description the previously set description would appear instead of the measurement.

Overrides:

selectItem in class Monitor

Parameters:

item - item to select

receiveNotificationOnCoordinateChange

public void receiveNotificationOnCoordinateChange(GraphicComponent gc)

Gets notification from its selected components if their coordinates have been changed. A measurement monitor should recompute its measurement then.

Overrides:

receiveNotificationOnCoordinateChange in class Monitor

Parameters:

gc - component changing coordinates

measurement

public abstract double measurement()

Returns the measurement measured by the monitor as a double.

getCoordinates

public void getCoordinates(float[] c)

Returns the centroid of the selected elements.

Overrides:

getCoordinates in class GraphicComponent

Parameters:

c - allocated array where coordinates will be put

getCoordinates

public void getCoordinates(ComponentElement item,
                           float[] c)

Returns the centroid of the selected elements.

Overrides:

getCoordinates in class GraphicComponent

Parameters:

item - specific part of the component

c - allocated array where coordinates will be put

getDescription

public java.lang.String getDescription()

Returns the measurement as a description.

Overrides:

getDescription in class GraphicComponent

Returns:

short description as String

getDescription

public java.lang.String getDescription(ComponentElement element)

Returns the measurement as a description.

Overrides:

getDescription in class GraphicComponent

Parameters:

element - specific part of the component

Returns:

short description as String

refresh

public void refresh()

Deletes the position and the value of the measurement to recount.

getMonitorColor

protected byte[] getMonitorColor()
