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.

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.
