I am encountering an error in DSpace 3 and DSpace 4 code when I attempt to
harvest a collection containing a withdrawn item.
I have started my investigation, and I am curious to understand the
intention of this query
https://github.com/DSpace/DSpace/blob/dspace-4_x/dspace-oai/src/main/java/org/dspace/xoai/data/DSpaceItemDatabaseRepository.java#L227-L231
Can you explain the purpose of the following test of withdrawn=TRUE?
public ListItemIdentifiersResult getItemIdentifiers(
List<Filter> filters, int offset, int length)
{
List<Object> parameters = new ArrayList<Object>();
List<Object> countParameters = new ArrayList<Object>();
String query = "SELECT i.* FROM item i ";
String countQuery = "SELECT COUNT(*) as count FROM item i";
List<String> whereCond = new ArrayList<String>();
for (Filter filter : filters)
{
if (filter.getFilter() instanceof DSpaceFilter)
{
DSpaceFilter dspaceFilter = (DSpaceFilter)
filter.getFilter();
DatabaseFilterResult result =
dspaceFilter.getWhere(_context);
if (result.hasResult())
{
if (filter.getScope() == FilterScope.MetadataFormat)
whereCond.add("(i.withdrawn=TRUE OR ("
+ result.getWhere() + "))");
else
whereCond.add("(" + result.getWhere() + ")");
parameters.addAll(result.getParameters());
countParameters.addAll(result.getParameters());
}
}
}
