## Class ReadResult

- java.lang.Object
- - org.apache.olingo.odata2.api.ep.callback.ReadResult

- Direct Known Subclasses:
    ReadEntryResult, ReadFeedResult

      public abstract class ReadResult
      extends Object

  A `ReadResult` represents an inlined navigation property which points to an entry or feed. The `ReadResult` contains the `EntityProviderReadProperties` which were used for read, the `navigationPropertyName`, the read/de-serialized inlined entity and information whether the inlined content is a `feed` (multiplicity of `1..m`) or a single `entry` (multiplicity of `0..1` or `1..1`). If inlined navigation property is `nullable` the `ReadResult` has the `navigationPropertyName` and a `NULL` entry set.
