public interface DeepCompare

Classes that implement this interface can deep-compare [for equality only, not order] with another instance. They do a deep compare. If there is any semantically significant difference, an implementer throws an Exception to be thrown with a chain of causes describing the chain of field references and indices that get you to the miscompared point.

deepCompare

void deepCompare(DeepCompare other,
               TreePath myLocation)
                 throws DeepInequalityException

参数:

other - the other comparand that's being compared to me

myLocation - the path that got to me. In the root, myLocation is null. To process the scalar foo field of the root we will make a recursive call with a TreePath whose fieldName is "bar" and whose index is -1 and whose parent is null. To process the plural bar field of the root we will make a recursive call with a TreePath whose fieldName is "foo" and whose index is -1 and whose parent is also null.

抛出:

DeepInequalityException
