How to use - ComparableComparisonStrategy

[ClaudioNazareth]

Hi,

I'm trying to use the ComparableComparisonStrategy , I already implemented the interface Comparable < Object> in my classes , but the method
public static boolean isComparableType (Class end <?> Clazz ) {
return BigDecimal.class.equals ( clazz ) ;
} Always returns false . Can you help me ?

obs: I do not understand how this method works

The ComparableComparisonStrategy is only for BigDecimals?

Hi,

I just took a look at the code and you are right. The strategy will currently only activate for BigDecimals. There are two things we can do:

1. I can (and will) change the isComparableType method to allow more built-in Java types

2. For your use case, you can use the comparison configuration API to manually define the strategy for your types like so:

   ObjectDifferBuilder.startBuilding()
           .comparison().ofType(BigInteger) // <- change this to your type
           .toUseCompareToMethod()
   

Hope this helps!
