syms
Symbolizer[] syms(Code)

Constructor Detail

DrawFeatureCommand
public DrawFeatureCommand(Feature feature, ILayer layer) throws IOException(Code)
	Parameters: feature - Parameters: layer - layer that feature is from throws: IOException -

DrawFeatureCommand
public DrawFeatureCommand(Feature feature, CoordinateReferenceSystem crs)(Code)
	Parameters: feature - Parameters: crs -

DrawFeatureCommand
public DrawFeatureCommand(Feature feature)(Code)
	Parameters: feature -

Method Detail

dispose
public void dispose()(Code)
	Diposes of the image if it has been created. Only needs to be called if the command has not been sent to the IMapDisplay .

finalize
protected void finalize()(Code)

getColor
public Color getColor()(Code)
	Returns the color.

getValidArea
public Rectangle getValidArea()(Code)

preRender

public void preRender()(Code)

Renders the feature to a image buffer so that drawing command will be fast. If feature is large you should call this so that there isn't a big delay in the display thread.

setMap() must be called before calling this method.

If this method is called then this object must be sent to the ViewportPane or be disposed because a Image object is created that needs to be disposed.

run
public void run(IProgressMonitor monitor) throws Exception(Code)
	See Also: net.refractions.udig.project.command.MapCommand.run

setColor
public void setColor(Color color)(Code)
	Parameters: color - The color to set.

setSymbolizers
public void setSymbolizers(Symbolizer[] syms)(Code)
	Allows the symbolizers to be set Parameters: syms - symbolizers to use to draw features.

setValid
public void setValid(boolean valid)(Code)
