public PageImpl(List<T> content,
                Pageable pageable,
                long total)
```
    Constructor of PageImpl.

    content - the content of this page, must not be null.
    
    pageable - the paging information, must not be null.
    
    total - the total amount of items available. The total might be adapted considering the length of the content given, if it is going to be the content of the last page. This is in place to mitigate inconsistencies.
