                 int rendererIndex,
                 PlotRenderingInfo info)

Draws the annotation. This method is called by the drawing code in the XYPlot class, you don't normally need to call this method directly.

Specified by:

draw in interface XYAnnotation

Specified by:

draw in class AbstractXYAnnotation

Parameters:

g2 - the graphics device.

plot - the plot.

dataArea - the data area.

domainAxis - the domain axis.

rangeAxis - the range axis.

rendererIndex - the renderer index.

info - if supplied, this info object will be populated with entity information.

equals

Tests this object for equality with an arbitrary object.

Overrides:

equals in class AbstractXYAnnotation

Parameters:

obj - the object (null permitted).

Returns:

A boolean.

hashCode

Returns a hash code for this object.

Overrides:

hashCode in class AbstractXYAnnotation

Returns:

A hash code.

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Returns a clone of the annotation.

Specified by:

clone in interface org.jfree.util.PublicCloneable

Overrides:

clone in class AbstractAnnotation

Returns:

A clone.

Throws:

java.lang.CloneNotSupportedException - if the annotation can't be cloned.

                  throws java.io.IOException

Provides serialization support.

Parameters:

stream - the output stream.

Throws:

java.io.IOException - if there is an I/O error.

readObject

private void readObject(java.io.ObjectInputStream stream)
                 throws java.io.IOException,
                        java.lang.ClassNotFoundException

Provides serialization support.

Parameters:

stream - the input stream.

Throws:

java.io.IOException - if there is an I/O error.

java.lang.ClassNotFoundException - if there is a classpath problem.
