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
