Determining available operators at runtime

I would like to be able to retrieve the available operators for an object at runtime, possibly in a similar way as the getMethod() call.

In particular, I need to be able to call the less-than/greater-than operators of an object at runtime.

Basically, I have a bunch of primitives that have been cast to the Object object-type. I need to perform comparisons between them at run-time. (I do know that the objects being compared will be of the same original type, and have implemented my own type-checking).

Alternatively.. Maybe there is a way to programatically cast these objects back to their original type, and use their native comparison operators.. somehow?

Thanks f开发者_JS百科or any assistance.

There is no way in Java to get available operators. For comparison the class should (you may do this thru reflection also) implement the Comparable interface.

If they are auto-boxed primitive types, the set of arithmetic operators is identical for all types other than Boolean, and the set of bitwise operators ditto apart from the two FP types.
