Method Detail

draw

public void draw(java.awt.Graphics2D g2,
                 XYPlot plot,
                 java.awt.geom.Rectangle2D dataArea,
                 ValueAxis domainAxis,
                 ValueAxis rangeAxis,
                 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

public boolean equals(java.lang.Object obj)

Tests this object for equality with an arbitrary object.

Overrides:

equals in class AbstractXYAnnotation

Parameters:

obj - the object (null permitted).

Returns:

A boolean.

hashCode

public int hashCode()

Returns a hash code for this object.

Overrides:

hashCode in class java.lang.Object

Returns:

A hash code.

clone

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 java.lang.Object

Returns:

A clone.

Throws:

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