    Description
    static <T extends org.elasticsearch.cluster.Diffable<T>>
    T
    assertDiffApplication(T remoteChanges, T localInstance, org.elasticsearch.cluster.Diff<T> diffs)
    Asserts that changes are applied correctly, i.e.
    static <T extends org.elasticsearch.common.io.stream.Writeable>
    T
    assertSerialization(T testInstance, org.elasticsearch.common.io.stream.NamedWriteableRegistry namedWriteableRegistry, org.elasticsearch.common.io.stream.Writeable.Reader<T> reader)
    Asserts that testInstance can be correctly.
    static <T extends org.elasticsearch.common.io.stream.Writeable>
    T
    copyInstance(T diffs, org.elasticsearch.common.io.stream.NamedWriteableRegistry namedWriteableRegistry, org.elasticsearch.common.io.stream.Writeable.Reader<T> reader)
    Simulates sending diffs over the wire
    static <T extends org.elasticsearch.cluster.Diffable<T>>
    void
    testDiffableSerialization(Supplier<T> testInstance, Function<T,T> modifier, org.elasticsearch.common.io.stream.NamedWriteableRegistry namedWriteableRegistry, org.elasticsearch.common.io.stream.Writeable.Reader<T> reader, org.elasticsearch.common.io.stream.Writeable.Reader<org.elasticsearch.cluster.Diff<T>> diffReader)
    Tests making random changes to an object, calculating diffs for these changes, sending this diffs over the wire and appling these diffs on the other side.

    • assertDiffApplication

      public static <T extends org.elasticsearch.cluster.Diffable<T>> T assertDiffApplication(T remoteChanges, T localInstance, org.elasticsearch.cluster.Diff<T> diffs)
      Asserts that changes are applied correctly, i.e. that applying diffs to localInstance produces that object equal but not the same as the remoteChanges instance.
