    Returns:
    
    the size of the Slice.
  - getNumberOfElements
```
int getNumberOfElements()
```
    Returns the number of elements currently on this Slice.
    
    Returns:
    
    the number of elements currently on this Slice.
  - getContent
```
List<T> getContent()
```
    Returns the page content as List.
    
    Returns:
  - hasContent
```
boolean hasContent()
```
    Returns whether the Slice has content at all.
    
    Returns:
  - getSort
```
Sort getSort()
```
    Returns the sorting parameters for the Slice.
    
    Returns:
  - isFirst
```
boolean isFirst()

    Returns if there is a previous Slice.
    
    Returns:
    
    if there is a previous Slice.
  - nextPageable
```
Pageable nextPageable()
```
    Returns the Pageable to request the next Slice. Can be null in case the current Slice is already the last one. Clients should check hasNext() before calling this method to make sure they receive a non-null value.
    
    Returns:
  - previousPageable
```
Pageable previousPageable()
```
    Returns the Pageable to request the previous Slice. Can be null in case the current Slice is already the first one. Clients should check hasPrevious() before calling this method make sure receive a non-null value.
    
    Returns:
  - map
```
<S> Slice<S> map(Converter<? super T,? extends S> converter)
```
    Returns a new Slice with the content of the current one mapped by the given Converter.
    
    Parameters:
    
    converter - must not be null.
    
    Returns:
    
    a new Slice with the content of the current one mapped by the given Converter.
