 int maxResults)

Constructs a new empty paged array list.

Parameters:

keyset - The keyset page for this page

totalSize - The total size of the result

firstResult - The first result index within the overall result

maxResults - The maximum result count for a page

public PagedArrayList(Collection<? extends T> collection,
 KeysetPage keyset,
 long totalSize,
 int firstResult,
 int maxResults)

Constructs a new paged array list from the given collection.

Parameters:

collection - The collection of elements for this page

keyset - The keyset page for this page

totalSize - The total size of the result

firstResult - The first result index within the overall result

maxResults - The maximum result count for a page

Method Details

getSize

public int getSize()

Description copied from interface: PagedList

Returns the actual size of this page.

Specified by:

getSize in interface PagedList<T>

Returns:

The actual size

• List.size()

getTotalSize

public long getTotalSize()

Description copied from interface: PagedList

Returns the total size of the list or -1 if the count query was disabled via PaginatedCriteriaBuilder.withCountQuery(boolean).

Specified by:

getTotalSize in interface PagedList<T>

Returns:

The total size or -1 if the count query was disabled

getPage

public int getPage()

Description copied from interface: PagedList

Returns the number of this page, numbered from 1.

Specified by:

getPage in interface PagedList<T>

Returns:

The number of this page

getTotalPages

public int getTotalPages()

Description copied from interface: PagedList

Returns the number of total pages.

Specified by:

getTotalPages in interface PagedList<T>

Returns:

The number of total pages

getFirstResult

public int getFirstResult()

Description copied from interface: PagedList

Returns the position of the first result, numbered from 0. This is the position which was actually queried. This value might be different from KeysetPage.getFirstResult(). If this list was queried with an entity id which does not exist, this will return -1;

Specified by:

getFirstResult in interface PagedList<T>

Returns:

The position of the first result or -1 if the queried entity id does not exist

getMaxResults

public int getMaxResults()

Description copied from interface: PagedList

Returns the maximum number of results. This is the maximum number which was actually queried. This value might be different from KeysetPage.getFirstResult().

Specified by:

getMaxResults in interface PagedList<T>

Returns:

The maximum number of results

getKeysetPage

public KeysetPage getKeysetPage()

Description copied from interface: PagedList

Returns the key set page for this paged list which can be used for key set pagination. The key set page may be null if key set pagination wasn't used.

Specified by:

getKeysetPage in interface PagedList<T>

Returns:

The key set
