Method Detail

getCurrentPage

public List<DocumentModel> getCurrentPage()

Description copied from interface: PageProvider

Returns the current page of results.

This method is designed to be called from higher levels. It therefore ensures cheapness of repeated calls, rather than data consistency. There is a refresh() method for that.

Specified by:

getCurrentPage in interface PageProvider<DocumentModel>

Specified by:

getCurrentPage in class AbstractPageProvider<DocumentModel>

Returns:

the current page

getMaxResults

public long getMaxResults()

Returns the maximum number of results or 0 if there is no limit.

Since:

5.6

getPageLimit

public long getPageLimit()

Returns the page limit. The n first page we know they exist. We don't compute the number of page beyond this limit.

Specified by:

getPageLimit in interface PageProvider<DocumentModel>

Overrides:

getPageLimit in class AbstractPageProvider<DocumentModel>

Since:

5.8

setMaxResults

public void setMaxResults(long maxResults)

Sets the maximum number of result elements.

Since:

5.6

getCurrentSelectPage

public PageSelections<DocumentModel> getCurrentSelectPage()

Description copied from interface: PageProvider

Returns the current page of results wrapped in a PageSelection item.

By default, no entry is selected, unless PageProvider.setSelectedEntries(List) has been called before.

Specified by:

getCurrentSelectPage in interface PageProvider<DocumentModel>

Overrides:

getCurrentSelectPage in class AbstractPageProvider<DocumentModel>

getCurrentQuery

public String getCurrentQuery()

refresh

public void refresh()

Description copied from class: AbstractPageProvider

Refresh hook, to override for custom behavior

When overriding it, call super.refresh() as last statement to make sure that the PageProviderChangedListener is called with the up-to-date @{code PageProvider} state.

Specified by:

refresh in interface PageProvider<DocumentModel>

Overrides:

refresh in class AbstractPageProvider<DocumentModel>
