Interface ExtentDestroyI

  • All Superinterfaces:
    CallbackI, CallbackI.Z, Pointer
    All Known Implementing Classes:
    ExtentDestroy
    Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

    @FunctionalInterface
    public interface ExtentDestroyI
    extends CallbackI.Z
    Instances of this interface may be set to the ExtentHooks struct.

    Type

    
     bool (*) (
         extent_hooks_t *extent_hooks,
         void *addr,
         size_t size,
         bool committed,
         unsigned int arena_ind
     )
    • Method Detail

      • getSignature

        default java.lang.String getSignature()
        Description copied from interface: CallbackI
        Returns the dyncall signature for this callback function. [INTERNAL API]
        Specified by:
        getSignature in interface CallbackI
        Returns:
        the dyncall signature
      • callback

        default boolean callback​(long args)
        Description copied from interface: CallbackI.Z
        Will be called by native code.
        Specified by:
        callback in interface CallbackI.Z
        Parameters:
        args - pointer to a DCArgs iterator
        Returns:
        the value to store to the result DCValue
      • invoke

        boolean invoke​(long extent_hooks,
                       long addr,
                       long size,
                       boolean committed,
                       int arena_ind)
        Extent destruction hook.

        An extent destruction function conforms to the extent_destroy_t type and unconditionally destroys an extent at given addr and size with committed/decommited memory as indicated, on behalf of arena arena_ind. This function may be called to destroy retained extents during arena destruction (see arena.i.destroy).
