  • Method Summary

    Modifier and Type Method 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​(java.util.function.Supplier<T> testInstance, java.util.function.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.

    • copyInstance

      public 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) throws java.io.IOException
      Simulates sending diffs over the wire
      Throws:
      java.io.IOException

    • testDiffableSerialization

      public static <T extends org.elasticsearch.cluster.Diffable<T>> void testDiffableSerialization​(java.util.function.Supplier<T> testInstance, java.util.function.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) throws java.io.IOException
      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.
      Throws:
      java.io.IOException

    • assertSerialization

      public 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) throws java.io.IOException
      Asserts that testInstance can be correctly.
      Throws:
      java.io.IOException
