AbstractPageProvider
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.
