| LabelDisplayElement | | public class LabelDisplayElement extends GeometryDisplayElement implements DisplayElement,Serializable(Code) | | DisplayElement that encapsulates a GM_Object (geometry), a
ParameterValueType (caption) and a TextSymbolizer (style).
The graphical (say: screen) representations of this DisplayElement are Label-instances.
These are generated either when the paint-method is called or assigned externally
using the setLabels- or addLabels-methods.

| Method Summary | |
| public void | addLabel(Label label)
Adds a Label representation that is to be considered when the
LabelDisplayElement is painted to the view. | | public void | addLabels(Label[] labels)
Adds Label representations that are to be considered when the
LabelDisplayElement is painted to the view. | | public void | clearLabels()
Removes all Label representations for this
LabelDisplayElement. | | public boolean | doesScaleConstraintApply(double scale)
| | public ParameterValueType | getLabel()
Returns the caption of the label as ParameterValueType. | | public void | paint(Graphics g, GeoTransform projection, double scale)
Renders the DisplayElement to the submitted graphic context. | | public void | setLabel(ParameterValueType label)
Sets the caption of the label. | | public void | setLabels(Label[] labels)
Sets the Label representations that are to be considered when the
LabelDisplayElement is painted to the view. |
| LabelDisplayElement | | public LabelDisplayElement(Feature feature, Geometry geometry, TextSymbolizer symbolizer)(Code) | | Creates a new LabelDisplayElement object.
Parameters:
feature - associated Feature
Parameters:
geometry - associated GM_Object
Parameters:
symbolizer - associated TextSymbolizer |
| addLabel | | public void addLabel(Label label)(Code) | | Adds a Label representation that is to be considered when the
LabelDisplayElement is painted to the view.
Parameters:
label - |
| addLabels | | public void addLabels(Label[] labels)(Code) | | Adds Label representations that are to be considered when the
LabelDisplayElement is painted to the view.
Parameters:
labels - |
| clearLabels | | public void clearLabels()(Code) | | Removes all Label representations for this
LabelDisplayElement.
|
| doesScaleConstraintApply | | public boolean doesScaleConstraintApply(double scale)(Code) | | |
| paint | | public void paint(Graphics g, GeoTransform projection, double scale)(Code) | | Renders the DisplayElement to the submitted graphic context. If the Label-represenations
have been assigned externally, these labels are used, else Label-instances are
created automatically using the LabelFactory.
Parameters:
g - Graphics context to be used
Parameters:
projection - GeoTransform to be used |
| setLabels | | public void setLabels(Label[] labels)(Code) | | Sets the Label representations that are to be considered when the
LabelDisplayElement is painted to the view.
Parameters:
labels - |
