getCurrentPage

public List<LogEntry> 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 the PageProviderDefinition, 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() and AbstractPageProvider.refresh().

Fields AbstractPageProvider.errorMessage and AbstractPageProvider.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 in CoreQueryAndFetchPageProvider 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() and AbstractPageProvider.setCurrentHigherNonEmptyPageIndex(int). In this case, CoreQueryDocumentPageProvider is a good example.

Specified by:

getCurrentPage in interface PageProvider<LogEntry>

Specified by:

getCurrentPage in class AbstractPageProvider<LogEntry>

Returns:

the current page

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<LogEntry>

Overrides:

refresh in class AbstractPageProvider<LogEntry>

getResultsCount

public long getResultsCount()

Description copied from interface: PageProvider

Returns the number of result elements if available or a negative value if it is unknown: UNKNOWN_SIZE if it is unknown as query was not done, and since 5.5, UNKNOWN_SIZE_AFTER_QUERY if it is still unknown after query was done.

Specified by:

getResultsCount in interface PageProvider<LogEntry>

Overrides:

getResultsCount in class AbstractPageProvider<LogEntry>

getSortInfos

public List<SortInfo> getSortInfos()

Description copied from interface: PageProvider

Returns the complete list of sorting info for this provider

Specified by:

getSortInfos in interface PageProvider<LogEntry>

Overrides:

getSortInfos in class AbstractPageProvider<LogEntry>
