Constructor Details

FilteredPageImpl

public FilteredPageImpl(@Nonnull
 PageRequest pageRequest,
 int size,
 @Nonnull
 SortedMap<Integer,T> valueMap,
 boolean lastPage)

Method Details

forEach

public void forEach(@Nonnull
 Consumer<? super T> action)

Description copied from interface: Page

Performs an action on each result in the page.

Specified by:

forEach in interface Page<T>

Parameters:

action - the action to apply to each result

Since:

6.3

getIsLastPage

public boolean getIsLastPage()

Specified by:

getIsLastPage in interface Page<T>

Returns:

true if there are no more results; otherwise, false if at least one more page, perhaps partially filled but not empty, of results is available

getLimit

public int getLimit()

Specified by:

getLimit in interface Page<T>

Returns:

the original limit on the PageRequest that generated this page

getNextPageRequest

public PageRequest getNextPageRequest()

Specified by:

getNextPageRequest in interface Page<T>

Returns:

a request which can be used to retrieve the next page, which will be null if this was the last page

getOrdinalIndexedValues

@Nonnull
public SortedMap<Integer,T> getOrdinalIndexedValues()

Description copied from interface: Page

Get a map of the page values mapped by their ordinal values. For filtered pages, the ordinals are the ordinals in the underlying paged collection.

Specified by:

getOrdinalIndexedValues in interface Page<T>

Returns:

values mapped by their ordinal value in the page

getSize

public int getSize()

Specified by:

getSize in interface Page<T>

Returns:

the number of results in the page

getStart

public int getStart()

Specified by:

getStart in interface Page<T>

Returns:

the offset into the overall result set the page starts at (0 based)

getValues

@Nonnull
public Iterable<T> getValues()

Specified by:

getValues in interface Page<T>

Returns:

the page's results

stream

@Nonnull
public Stream<T> stream()

Specified by:

stream in interface Page<T>

Returns:

a Stream over the page's results

transform

@Nonnull
public <E> FilteredPageImpl<E> transform(@Nonnull
 Function<? super T,? extends E> transformFunction)

Description copied from interface: Page

Transforms the results on the page, producing a new Page with different values but all other properties (e.g. start and limit) unchanged.

Implementation note: Transformation is done eagerly to ensure the resulting Page does not retain a reference to the original results from the source page. If a transform is used purely to apply some set of side effects, consider using Page.forEach(java.util.function.Consumer<? super T>) instead.

Specified by:

transform in interface Page<T>

Type Parameters:

E - the target type

Parameters:

transformFunction - the transformer

Returns:

a new page with transformed results
