Method Detail

getCurrentPage

public List<NuxeoGroup> 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.
