Usage

From source file:com.microsoft.azure.serializer.CloudErrorDeserializer.java

@Override

        throws IOException, JsonProcessingException {
    JsonNode topNode = p.readValueAsTree();
    if (topNode == null) {
        return null;
    }//from  w w w  .j a  va2 s.  c o  m
    JsonNode errorNode = topNode.get("error");
    if (errorNode == null) {
        return null;
    }
    JsonParser parser = new JsonFactory().createParser(errorNode.toString());
    parser.setCodec(mapper);
    return parser.readValueAs(CloudError.class);
