[OpenJDK 2D-Dev] equals() and hashCode() verification in java.awt.image.ComponentSampleModel and its subclassses

[Jayathirth D V]

Hi Jim,

 

I am trying to modify/add equals()/hashCode() methods in java.awt.image.ComponentSampleModel() and its subclasses.

 

In BandedSampleModel and PixelInterleavedSampleModel I see that we have just hashCode() functions and not equals() and these hashCode() function are returning just constant value.

I am not able to find private variables or unique properties which are set in BandedSampleModel/PixelInterleavedSampleModel for the need to override equals()/hashCode() methods. 

Can we remove hashCode() function present BandedSampleModel/PixelInterleavedSampleModel and rely on ComponentSampleModel? What is the purpose of having hasCode() function returning constant value in these subclasses?

Please provide your inputs.

 

Thanks,

Jay
