  • Method Details

    • slice

      public ByteArrayView slice(int off, int len)
      Description copied from class: ByteArrayView
      Create a new ByteArrayView which wraps a portion of this one NB: no data is copied when doing this
      Specified by:
      slice in class ByteArrayView
      Parameters:
      off - the initial offset of the window (relative to the current window)
      len - the length of the window
      Returns:
      the new ByteArrayView

    • view

      public ByteBuffer view(int off, int len)
      Description copied from class: ByteArrayView
      Create a new ByteBuffer which wraps a portion of this one NB: no data is copied when doing this
      Specified by:
      view in class ByteArrayView
      Parameters:
      off - the initial offset of the window (relative to the current window)
      len - the length of the window
      Returns:
      a ByteBuffer whose arrayOffset() and limit() are the offset and length provided

    • view

      public ByteBuffer view()
      Description copied from class: ByteArrayView
      Create a new ByteBuffer which wraps all of this one NB: no data is copied when doing this
      Specified by:
      view in class ByteArrayView
      Returns:
      a ByteBuffer whose arrayOffset() and limit() are the offset() and length() of this view

    • array

      public byte[] array()
      Description copied from class: ByteArrayView
      Returns a reference to the backing array for this view. Note that the view might only be of a part of the returned array: this means you should only access the array between offsets ByteArrayView.offset() and offset() + ByteArrayView.length(). NB: no data is copied when doing this
      Specified by:
      array in class ByteArrayView
      Returns:
      the backing array

    • offset

      public int offset()
      Description copied from class: ByteArrayView
      return the offset into the backing array of this view NB: no data is copied when doing this
      Specified by:
      offset in class ByteArrayView
      Returns:
      the offset in bytes

    • length

      public int length()
      Description copied from class: ByteArrayView
      return the length of this view NB: no data is copied when doing this
      Specified by:
      length in class ByteArrayView
      Returns:
      the length in bytes

    • copy

      public ByteArrayView copy(int off, int len)
      Description copied from class: ByteArrayView
      Create a new ByteArrayView which wraps a new byte[] containing a copy of this view's data NB: this method copies the underlying data
      Specified by:
      copy in class ByteArrayView
      Parameters:
      off - the initial offset of the window (relative to the current window)
      len - the length of the window
      Returns:
      the new ByteArrayView
