List of readDelta() Examples

Examples of readDelta()

com.netflix.zeno.fastblob.io.FastBlobReader.readDelta()
Read a delta from the specified stream. Apply the delta to the FastBlobStateEngine supplied in the constructor of this class.
This method performs no validation of the data. It is assumed that the data currently represented in the FastBlobStateEngine is in the state which the server was in when it was produced this delta. Otherwise, the results are undefined.
it.unimi.dsi.io.InputBitStream.readDelta()
org.eclipse.core.internal.watson.ElementTreeReader.readDelta()
Reads an element tree delta from the input stream, and reconstructs it as a delta on the given tree.

Examples of com.netflix.zeno.fastblob.io.FastBlobReader.readDelta()

        FastBlobReader reader = new FastBlobReader(stateEngine);
        reader.readSnapshot(new ByteArrayInputStream(snapshot1));


        TestTypeDeserializationStateListener listener = new TestTypeDeserializationStateListener();
        stateEngine.setTypeDeserializationStateListener("TypeF", listener);
        reader.readDelta(new ByteArrayInputStream(delta));


        Assert.assertEquals(3, listener.getRemovedValuesSize());
        Assert.assertEquals(2, listener.getRemovedValueOrdinal(3));
        Assert.assertEquals(2, listener.getAddedValuesSize());
        Assert.assertEquals(10, listener.getAddedValueOrdinal(11));
