    Type to wrap a single object returned by ThinLTO.

    Layout

    
     struct LTOObjectBuffer {
         char const * Buffer;
         size_t Size;
     }
    • Field Detail

      • SIZEOF

        The struct size in bytes.
      • ALIGNOF

        The struct alignment in bytes.
      • BUFFER, SIZE

    • Constructor Detail

      • LTOObjectBuffer

        public LTOObjectBuffer​(java.nio.ByteBuffer container)
        Creates a LTOObjectBuffer instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

        The created instance holds a strong reference to the container object.

    • Method Detail

      • sizeof

        public int sizeof()
        Description copied from class: Struct
        Returns sizeof(struct).
        Specified by:
        sizeof in class Struct
      • Buffer

        public java.nio.ByteBuffer Buffer()
        Returns a ByteBuffer view of the data pointed to by the Buffer field.
      • Size

        public long Size()
        Returns the value of the Size field.
      • malloc

        public static LTOObjectBuffer malloc()
        Returns a new LTOObjectBuffer instance allocated with memAlloc. The instance must be explicitly freed.
      • calloc

        public static LTOObjectBuffer calloc()
        Returns a new LTOObjectBuffer instance allocated with memCalloc. The instance must be explicitly freed.
      • create

        public static LTOObjectBuffer create​(long address)
        Returns a new LTOObjectBuffer instance for the specified memory address.
      • createSafe

        @Nullable
        public static LTOObjectBuffer createSafe​(long address)
        Like create, but returns null if address is NULL.
      • create

        public static LTOObjectBuffer.Buffer create​(long address,
                                                    int capacity)
        Create a LTOObjectBuffer.Buffer instance at the specified memory.
        Parameters:
        address - the memory address
        capacity - the buffer capacity
      • createSafe

        @Nullable
        public static LTOObjectBuffer.Buffer createSafe​(long address,
                                                        int capacity)
        Like create, but returns null if address is NULL.
      • mallocStack

        public static LTOObjectBuffer mallocStack()
        Returns a new LTOObjectBuffer instance allocated on the thread-local MemoryStack.
      • callocStack

        public static LTOObjectBuffer callocStack()
        Returns a new LTOObjectBuffer instance allocated on the thread-local MemoryStack and initializes all its bits to zero.
      • mallocStack

        public static LTOObjectBuffer mallocStack​(MemoryStack stack)
        Returns a new LTOObjectBuffer instance allocated on the specified MemoryStack.
        Parameters:
        stack - the stack from which to allocate
      • callocStack

        public static LTOObjectBuffer callocStack​(MemoryStack stack)
        Returns a new LTOObjectBuffer instance allocated on the specified MemoryStack and initializes all its bits to zero.
        Parameters:
        stack - the stack from which to allocate
      • nBuffer

        public static java.nio.ByteBuffer nBuffer​(long struct)
        Unsafe version of Buffer.
      • nSize

        public static long nSize​(long struct)
        Unsafe version of Size().
