var handles also uses the polymorphic signature trick to avoid boxing/unboxing of the arguments you get with the reflection
(the same trick also allows to introduce 64 bits index array in the future BTW).
and you can also do all memory operations on arrayish values (array or ByteBuffer) even un-aligned acces.
- Flowdalic 10y agoCare to extend on that "polymorphic signature trick"?
- aardvark179 10y agoThere is an annotation that can be used in the JDK to mark methods as polymorphic. The compiler will declare the method call with the types of the arguments and result where it is called, and the VM will handle it. This allows a very small set of core methods to take variable numbers or types of arguments without boxing them or having to put them in an array.
