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.

public boolean equals (Object obj)

Tests this annotation for equality with an arbitrary object.

Parameters
obj the object to test against.
Returns
  • true or false.
