question: @ Override public boolean equals ( Object obj ) { if ( obj == this ) { return true ; } if ( ! ( obj instanceof StatisticalLineAndShapeRenderer ) ) { return false ; } StatisticalLineAndShapeRenderer that = ( StatisticalLineAndShapeRenderer ) obj ; if ( ! PaintUtilities . equal ( this . errorIndicatorPaint , that . errorIndicatorPaint ) ) { return false ; } if ( ! ObjectUtilities . equal ( this . errorIndicatorStroke , that . errorIndicatorStroke ) ) { return false ; } return super . equals ( obj ) ; }
