public interface CallbackI
extends Pointer

Base interface for dynamically created native functions that call into Java code. Pointers to such functions can be passed to native APIs as callbacks.

This interface does not define a callback method, therefore it should not be implemented directly. The following inner interfaces should be used instead:

• CallbackI.V
• CallbackI.Z
• CallbackI.B
• CallbackI.S
• CallbackI.I
• CallbackI.J
• CallbackI.F
• CallbackI.D
• CallbackI.P
