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.
