draw
in classAbstractXYAnnotation
- 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 classAbstractXYAnnotation
- Parameters:
obj
- the object to test against (null
permitted).- Returns:
true
orfalse
.
-

hashCode
in classAbstractXYAnnotation
- Returns:
- A hash code.
-
clone
public java.lang.Object clone() throws java.lang.CloneNotSupportedException
