Interface ILabelable

All Known Subinterfaces:

GraphicLayer, VectorLayer

All Known Implementing Classes:

DefaultGraphicLayer, FLyrVect

public interface ILabelable

This interface enables support for labeling an object such as a layer, but also others, if any. It gives support for detecting if labeling is being applied (isLabeled() and setIsLabeled()), to manage the labeling strategy (getLabelingStrategy() and setLabelingStrategy). The labeling is performed by the drawLabels(..) method.

Method Detail

drawLabels

void drawLabels(java.awt.image.BufferedImage image,
              java.awt.Graphics2D g,
              ViewPort viewPort,
              org.gvsig.tools.task.Cancellable cancel,
              double scale,
              double dpi)
                throws org.gvsig.fmap.dal.exception.ReadException

Causes the labels to be drawn. The policy of process is determined by the LabelingStrategy previously set.

Parameters:

image -

g -

viewPort -

cancel -

scale -

dpi -

Throws:

org.gvsig.fmap.dal.exception.ReadException

getLabelingStrategy

ILabelingStrategy getLabelingStrategy()

Returns the current labeling strategy

Returns:

ILabelingStrategy

isLabeled

boolean isLabeled()

Returns true if labels are drawn, or false otherwise.

Returns:

boolean telling if labels are drawn

printLabels

void printLabels(java.awt.Graphics2D g,
               ViewPort viewPort,
               org.gvsig.tools.task.Cancellable cancel,
               double scale,
               org.gvsig.compat.print.PrintAttributes properties)
                 throws org.gvsig.fmap.dal.exception.ReadException

Throws:

org.gvsig.fmap.dal.exception.ReadException

setIsLabeled

void setIsLabeled(boolean isLabeled)

Enables or disables the label drawing.

Parameters:

isLabeled, - if true then labels will be drawn

setLabelingStrategy

void setLabelingStrategy(ILabelingStrategy strategy)

Sets the new labeling strategy. Changes on the results will take effect next time the drawLabels(...) method is invoked.

Parameters:

strategy -
