org.apache.olingo.odata2.api.ep.entry.ODataEntry

Callback interface for the deep insert read calls (read of content). Typically the {@link #receiveReadProperties(EntityProviderReadProperties,EdmNavigationProperty)} method is calledwhen an inline navigation property is found and will be read.

The {@link #handleReadEntry(ReadEntryResult)} and {@link #handleReadFeed(ReadFeedResult)} methods are calledafter the inline navigation property was read and deliver the read (de-serialized) entity or list of entities. If inlined navigation property is nullable and not set a {@link ReadEntryResult} is given with thenavigationPropertyName and a NULL entry set.
