It probably should ignore... but probably also that's up to the class that contains the field. It would maybe be more forward-thinking of these subclasses called super.equals() and super.hashCode() as part of their processing rather than hoping to grab the right fields from the super class (which in my opinion should have been private fields in the first place... but that's a different religious hill to die on another day). |

This PR addresses the enhancements request in issue #2249.
Since the PR overrides
equals(), it must also overridehashCode()because the contract ofhashCode()specifies that objects that are equal must return the same code.The new methods intentionally ignore the
checkPlanefield, which holds auxiliary data used by theCameraclass.
