getCurrentPage
Description copied from class:AbstractPageProvider
Returns the list of current page items.Custom implementation can be added here, based on the page provider properties, parameters and
WhereClauseDefinition
on thePageProviderDefinition
, as well as search document, sort information, etc...Implementation of this method usually consists in setting a non-null value to a field caching current items, and nullifying this field by overriding
AbstractPageProvider.pageChanged()
andAbstractPageProvider.refresh()
.Fields
AbstractPageProvider.errorMessage
andAbstractPageProvider.error
can also be filled to provide accurate feedback in case an error occurs during the search.When items are retrieved, a call to
AbstractPageProvider.setResultsCount(long)
should be made to ensure proper pagination as implemented in this abstract class. The implementation inCoreQueryAndFetchPageProvider
is a good example when the total results count is known.If for performance reasons, for instance, the number of results cannot be known, a fall-back strategy can be applied to provide the "next" button but not the "last" one, by calling
AbstractPageProvider.getCurrentHigherNonEmptyPageIndex()
andAbstractPageProvider.setCurrentHigherNonEmptyPageIndex(int)
. In this case,CoreQueryDocumentPageProvider
is a good example.- Specified by:
getCurrentPage
in interfacePageProvider<T>
- Specified by:

in classAbstractPageProvider<T>
- Returns:
- the current page
-
getMembers
-
getMember
-
getPageLimit
public long getPageLimit()Description copied from class:AbstractPageProvider
Returns the page limit. The n first page we know they exist.- Specified by:
getPageLimit
in interfacePageProvider<T>
- Overrides:
getPageLimit
in classAbstractPageProvider<T>
-
isSortable
public boolean isSortable()Description copied from interface:PageProvider
Returns if this provider is sortable- Specified by:
isSortable
in interfacePageProvider<T>
- Overrides:
isSortable
in classAbstractPageProvider<T>
-
pageChanged
protected void pageChanged()Description copied from class:AbstractPageProvider
Page change hook, to override for custom behaviorWhen overriding it, call
super.pageChanged()
as last statement to make sure that thePageProviderChangedListener
is called with the up-to-date @{code PageProvider} state.- Overrides:
pageChanged
