question: @ Override public boolean equals ( Object obj ) { if ( obj == this ) { return true ; } if ( ! super . equals ( obj ) ) { return false ; } if ( ! ( obj instanceof XYDrawableAnnotation ) ) { return false ; } XYDrawableAnnotation that = ( XYDrawableAnnotation ) obj ; if ( this . x != that . x ) { return false ; } if ( this . y != that . y ) { return false ; } if ( this . displayWidth != that . displayWidth ) { return false ; } if ( this . displayHeight != that . displayHeight ) { return false ; } if ( this . drawScaleFactor != that . drawScaleFactor ) { return false ; } if ( ! ObjectUtilities . equal ( this . drawable , that . drawable ) ) { return false ; } return true ; }
