Examples with ReaderHelpData org.apache.servicecomb.codec.protobuf.codec.AbstractFieldCodec.ReaderHelpData used on opensource projects

Example 1 with ReaderHelpData

use of org.apache.servicecomb.codec.protobuf.codec.AbstractFieldCodec.ReaderHelpData in project incubator-servicecomb-java-chassis by apache.

the class TestParamDeserializer method testUpdateResult.

@Test
public void testUpdateResult() {
    String[] stringArray = new String[1];
    stringArray[0] = "abc";
    Object[] object = new Object[1];
    Object paramObject = paramDeserializer.updateResult(object, stringArray, new ReaderHelpData());
    Assert.assertNotNull(paramObject);
    Assert.assertEquals(paramObject, object);
}

Example 2 with ReaderHelpData

use of org.apache.servicecomb.codec.protobuf.codec.AbstractFieldCodec.ReaderHelpData in project incubator-servicecomb-java-chassis by apache.

the class AbstractDeserializer method deserialize.

@Override
public Object deserialize(JsonParser p, DeserializationContext ctxt) throws IOException, JsonProcessingException {
    Object result = createResult();
    for (String fieldName = p.nextFieldName(); fieldName != null; fieldName = p.nextFieldName()) {
        // p实际是ProtobufParser，其内部是可以直接取到proto field的，理论上可以根据id来索引
        // 可是field默认没暴露出来，所以，直接用name索引了
        ReaderHelpData helpData = readerHelpDataMap.get(fieldName);
        if (helpData == null) {
            continue;
        }
        JsonToken t = p.nextToken();
        // Note: must handle null explicitly here; value deserializers won't
        Object value = null;
        if (t == JsonToken.VALUE_NULL) {
            value = helpData.getDeser().getNullValue(ctxt);
        } else {
            value = helpData.getDeser().deserialize(p, ctxt);
        }
        result = updateResult(result, value, helpData);
    }
    return result;
