    • nextPageable

      default Pageable nextPageable()
      Create a pageable for querying the next page of data.

      A pageable may be created even if the end of data was reached to accommodate for cases when new data might be added to the repository. Use hasNext() to verify if you have reached the end.

      Returns:
      The next pageable

    • previousPageable

      default Pageable previousPageable()
      Create a pageable for querying the previous page of data.

      A pageable may be created even if the end of data was reached to accommodate for cases when new data might be added to the repository. Use hasPrevious() to verify if you have reached the end.

      Returns:
      The previous pageable

    • getOffset

      default long getOffset()
      Returns:
      The offset.

    • getSize

      default int getSize()
      Returns:
      The size of the slice.

      Maps the content with the given function.
      Type Parameters:
