public abstract class Callback extends Object implements Pointer, NativeResource
Base class for dynamically created native functions that call into Java code.

Callback instances use native resources and must be explicitly freed when no longer used by calling the free() method.

  • Method Details

    • address

      public long address()
      Description copied from interface: Pointer
      Returns the raw pointer address as a long value.
      Specified by:
      address in interface Pointer
      Returns:
      the pointer address

    • free

      public void free()
      Description copied from interface: NativeResource
      Frees any native resources held by this object.
      Specified by:
      free in interface NativeResource

    • get

      public static <T extends CallbackI> T get(long functionPointer)
      Converts the specified function pointer to the CallbackI instance associated with it.
      Type Parameters:
      T - the CallbackI instance type
      Parameters:
      functionPointer - a function pointer
      Returns:
      the CallbackI instance

    • getSafe

      public static <T extends CallbackI> @Nullable T getSafe(long functionPointer)
      Like get(long), but returns null if functionPointer is NULL.

    • free

      public static void free(long functionPointer)
      Frees any resources held by the specified function pointer.
      Parameters:
      functionPointer - the function pointer

    • equals

      public boolean equals(Object o)
      Overrides:
      equals in class Object

    • hashCode

      public int hashCode()
      Overrides:
      hashCode in class Object

    • toString

      public String toString()
      Overrides:
      toString in class Object
